Product information The pictured light sensor by manufacturer Sick, for door protection in trains and buses can be beneficially replaced by a compatible redesign. The so far relatively complex adjustment of the mirror optics, which focuses the ray on the reflector, ceases with the new light sensors. The new devices can be mounted “plug-and - play” on the designated places without any further adjustment. The solid, black anodized aluminum cases are protected against vandalism, by dispensing with destructible front glass or lense, respectively, so malfunctions due to scratched, misted ordirty glasses or lenses are dropped. The infrared-LEDs are deeply enough mounted in the case that aforementioned impairments are reliably eliminated. The light sensors are constructed as unilaterally (mounting right or left) or mutually operating reflex-light sensors for prism reflectors. The mutually operating devices have individually configurable plug-in jumpers, which make it possible to link the two independent monitoring lines with a Or-function on just one output relay or to put both sides independently on separated relays, respectively. Higly reliable relays with  3x 106 switching cycles are chosen. The relays switch with a clear “click” to enable a good acoustic verification of perfect function on-site. The devices are connected via one, two respectively, pluggable solid terminal strip (1,5mm2) in a significantly enlarged terminal compartment. For operational maintenance of older original Sick-light sensors: Replacement illuminants for Sick When the original illuminant with low-voltage lamp may not be available anymore, a plug-and-play compatibly applicable illuminant with 2 infrared LEDs is available.

WiMo  
A wing segment with a length of about 10m, and their production tools should be measured with high resulution over the entire surface to detect ripples and other errors in the range of  micrometers. For that purpose the fringe projection system "VEW Stereocam" was adapted to the measuring task by adding a laser tracker that transfers the point cloud of the individual measuring fields with a size of approximately 1 m² in a global coordinate systemup to 1000m². The measurement uncertainty of the system is about 10 microns. Due to the high measuring point density, it is possible to detect ripples in millimeter and submillimeter range with very different longitudinal expansion. Up to now measuring campaigns at different production sites are performed in order to secure the high quality standards in the manufacture of wings and avoid deviation. http://cordis.europa.eu/result/rcn/147160_de.html Project Information Funding authority EU, Grant Agreement Number-286745 runtime 01.04.2011 – 31.12.2015 Target VEW Development of a measurement system for measuring a wing and determination of waviness, cracks, roughness WiMo - Outer Wing Metrology

LWL 1000 coupler  
Technical data Electronic-optical coupler, DIN 41612 F32 low profile to 8 IR-transmitter and 8 IR-receiver Standard: without cover, adapter, 1000 MPF 8 transmitter micro lens for 2,2mm apertur to standard 1000 MPF Transferrate 10MBd at 650nm 8 receiver open collector, 2,2mm apertur to standard 1000 MPF Transferrate 5Mbit/s at 650nm Wiring Standard 17x AWG26-70mm, optional other length *All product and service marks contained herein are the trademarks or service marks of their respective owners. Product information For electrically decoupled and interference-free transmission of control signals between drive control units and power units of light rail vehicles, optical fibres and couplers from 8 transmitters and 8 IR-receivers are being used. The original modules by manufacturer Siemens had been joined by a suscep-tible flex printed circuit. The redesign of the couplers is made of a low profile DIN 41612 female multi point connector with special mounting on row z and d as well as the construction form F, 2 multilayer circuit boards, which are robustly connected with each other by 70mm AWG26 single wires. Other connection lengths can be manufactured optionally. Both multilayers carry the DIN 41612 female multipoint connector and also the optic coupler, with the arrangement of 8 receivers and 8 transmitters for standard 1000 micron plastic fibre (MPF). The optical modules are combined in a grey plastic carrier as an "optical coupler", on which an adapter for the connection with 16 optical fibres can be screwed on. The optical fibres lock in adapter B by a snap-in-connection and this way can be separated in the given arrangement from coupler A "in one piece". Alternatively, customer-specific assembled adapters with each 8 firmly moulded MPF by different colours for "receiver-" and "transmitter-" lines can be delivered. Length of MPF according to specifications. Individual wire designation. The couplers can be mounted into an Intermas connector housing for the construction type DIN 41612 F upon request so the female multi point connector can provide electric contacting on the one hand and the adapter with the 16 optical fibres on the coupler can maintain and secure the coupling of the IR-signals on the other hand. The 16 optical fibres are led out the connector housing strain-relieved with an according cable support sleeve. Datasheet Coupler LWL 1000 R-T-8 (MPF) RED  
Current transformer FL6/D2-3-400A-100mA  
Technical Data Measurement range unswitched 0…± 400A = 0….100mA Measurement range switched Shunt-resistance 100 ? 0,1% between J/K 0…±400A = 0…10V Auxiliary supply ± 15V DC 200mA Precision < 1% Ambient temp. range - 25…+70°C *All product and service marks contained herein are the trademarks or service marks of their respective owners. Product Information The redesigned version of the compensation current transformer FL6/D2-3-400A is completely compatible in connection to the original component. The devices convert (galvanically isolated) direct or alternating current proportionally that is guided through the “eye“ of the transformer into impressed current or respectively into voltage.   The devices feature a shunt resistor that is parallel-clamped onto terminals J and K if the current output is to be used as voltage output 400A = 10V . The precision of measurement is better than 1%.   The current transformer is operated with an auxiliary supply of ± 15V DC. The nominal measuring range of the current transfer is designed to ± 0…400A and provides a proportional output current of  0…100mA. The supplied shunt resistor is to be measured in such a way so that in the presence of a measuring range of 0...400A, a proportional output voltage of 0...10V will drop at the parallel switched shunt resistor. If the current transformer is to be used within another measurement range, then the shunt resistor must be adapted accordingly. Current transformer FL6/D2-3-400A-100mA  
VEW 6FH6010-1B RED nominal value converter  
Technical data Dimensions 100x160mm; 6 2/3 SEP Plug-in DIN 41612 H15 Supply voltage 24V DC nom. 2A Output PW Pulse width 60V, nom. 400Hz, PW 7,5...45% bei 0...20mA Output DC 24V 150mA, 60V 90mA Desired value input 2x, 500 Ohm 0...10V = 0...20mA Temp. range -25 … +70°C *All product and service marks contained herein are the trademarks or service marks of their respective owners. A fully pin- and function-compatible redesign, which can be operated via plug-and-play in the prewired application instead of the original module by the manufacturer Siemens. The nominal value converters 6FH 6010-1B Red. are built in isolated in the module rack of the ES902 system as centralized system in the Europe format with a mounting width of 6 2/3 SEP. The electrical connection is not made by a base plug-in connector in the module rack, but a plug-in connector DIN 41612 H15 on the front. All important functions of the module are also available on isolated measuring sockets on the front plate of the device. Function The nominal value transmission for all connected users of one train line takes place, independently from the distance to the sending nominal value converter, by pulse width control. The pulse width is controlled by the nominal value converter. The transmission frequency of the pulse width signal is nominally 400Hz (-0 +10%) with a output voltage of nominal 60V (-10 ... +10%). The PW-signal is potential-free and short-circuit-proof. The load current must not exceed 50mA. The pulse width at a impressed current of 0mA of the director is 7,5 % and increases linearly to 45 % at 20mA. 2 directors can be connected, of which the respective higher nominal value is being processed (maximum selection). The pulse width signal is being connected to the train line with a 2-pole relay, when the train control device is switched on, separated when the device is being switched off, resp. Only the nominal value converter may be active in the driver's cab. In addition to the function ,,nominal value converter'' the device provides electrically isolated output voltages of 24V 150mA and 60V 90mA. The voltage of 60V serves the transmission of train commands, the voltage of 24V serves as power supply for the commander of nominal values of the drive and brake. This voltage also supplies the relay for switching on the PW-signal as well as the lamp U ON, so the PW-signal is only switched on when the directors have a operating voltage and U ON is active.

Technical Data PCB-card 100x160mm; frontplate 9TE 3HE Plug-in DIN 41612 F48 Supply voltage nom. 110 DC, min. 66V DC, max. 154V DC Power max. 60VA Efficiency approx. 85% Temperature range -25... +70°C Output 5,1V 9A, 15V 0,2A Frontplate inspection sockets for UA1, UA2 LEDs and fuse *All product and service marks contained herein are the trademarks or service marks of their respective owners. Product Information Two international standards are used to regulate the compliance of electrical and electronic equipment in railway applications:                IEC571, EN50155, (UK) RIA12 RIA 12 (UK) requires overvoltage protection exceeding those of the requirements in the European standards. The present power supply meets or exceeds all the basic standards. The device was developed as a pin and functionally compatible redesign for a plug-and-play replacement of the power supply type 146025501 and has fully modular design. The input modules are designed for an input voltage of nom. 110V DC. According to EN50155, the necessary input voltage range is 0.7...1.25 x UN = 77...137V. The under/over voltage range needs to include both 66 V and 154V. The modules used are designed for 66V to 154V and are also equipped with an active transient protection, which securely eliminates the RIA12-specificed overvoltage (for 20 mS) of the 3.5V-times of the nominal input voltage of up to 385V, as well as peaks of up to 1800V/50µs. The MTBF is > 250.000h for the module, which meets the life requirements for railway equipment of 24h/d for 30a. The installation box meets the requirements for railway applications, is extremely robust and can resist a vibration load on three axels with and amplitude of 7.5mm at 5-150Hz and acceleration of 20m/s².

Technical data Design round 20mm Length: 45mm; 24mm L32mm; Length: 77mm; Brazen/ Alumnium Sensor surface 4mm Ø Reacting distance 1mm ± 0,2mm Switching behavior N Supply nom. 24V DC, 10V ... 30V Load current max. 0,06A, R-Load Ambient temperature -25°C ...max. +70°C Frequency max. 1200Hz *All product and service marks contained herein are the trademarks or service marks of their respective owners. Technical description The position indicator K7849-71, A540392 respectively, by manufacturer Siemens are no longer available. Alternatively there is a fully measure- and function-compatible Redesign VEW K7849-71P.   The positioner scans the rim of a metallic lock washer inductively in the given application. The smallest tooth-gap-distance is 4mm with a depth of 4mm and a maximum tooth-gap-frequence of 1200Hz. The distance between the active sensor surface and the tooth’s target should not exceed 1,0mm. The output signal “A” with the plug identification “green” is N-shifting, meaning the signal changes when passing the target to 0V (GND), measured against +24V (UB). The supply voltage is not less than 10V DC max. 30V DC (nom. 24V). The load current may be 60mA R-load. The output connectors are designed for AMP-sockets. The positioners can be used in a temperature range of -25°C to +70°C. The mounting adjustment is done with a 20mm clamp connection at the rim of the device. When the given installation geometry makes an adjustment with a distance of 1,0mm to the target of the lock washer impossible, an according modification has to be made to ensure faultless function. Switching distance >1mm leads to count loss! Position indicator VEW K7849-71P A540392 RED
