Components in vehicles and on the railway operate in conditions that standard equipment cannot withstand: a fluctuating on-board supply voltage, vibration, temperatures ranging from frost to a hot engine compartment, and years of continuous operation. That is why selection depends on input voltage range, operating temperature, robust connections and long-term availability.
In this section we have grouped components for passenger and commercial vehicles, rolling stock, e-mobility and transport telematics. Here you will find power supplies, communication modules, displays, industrial computers, relays, connectors and sensors from manufacturers for which we are a specialised distributor.
A vehicle's on-board supply fluctuates when the engine starts and when loads are switched on. TRACOPOWER isolated DC/DC converters with a 9 to 36 V input cover both 12 V and 24 V on-board systems, while versions with a 43 to 160 V input are designed for 110 V networks. The TEN 20WIR and TEP 160WIR series are approved to EN 50155 for railway applications and operate from -40 °C. Our range also includes EEMB 3.7 V Li-Po rechargeable batteries with capacities from 500 to 2000 mAh for compact devices with their own power source.
For the power electronics of chargers and converters, we offer Diotec SiC MOSFETs rated at 1200 V and 65 A or 120 A in a TO247-4 package. For charging electric vehicles, Phoenix Contact Type 1 and Type 2 mobile charging cables rated at 32 A are available in single-phase and three-phase versions.
For switching lights, motors and auxiliary circuits, you can choose automotive relays from FCL Components, TE Connectivity and Panasonic with 12 V and 24 V coils, including 25 A types. For railway use, Finder industrial relays with 24 V and 110 V DC coils are designed for socket mounting. Marquardt rocker switches for automotive applications complete the controls.
Sonitron piezoelectric buzzers with driver operate at 5 to 80 V DC and are rated IP67. Piezo sirens for 12 to 24 V DC reach a sound level of 112 dB. Visaton full-range loudspeakers rated IP65 are used for voice announcements.
Fleet tracking and remote diagnostics require mobile connectivity and precise positioning. As a specialised Quectel distributor, we offer LTE and 5G modules, such as BG95 LPWA modules for LTE Cat M1 and Cat NB2 with integrated GNSS, or EG21-G LTE Cat 1 modules. For positioning alone, GNSS (GPS) modules are the right choice. Contactless identification is handled by 13.56 MHz RFID readers for MIFARE® and NFC.
For display and control units, you will find TFT displays from Display Visions, Winstar and 4D Systems, from 1.3" round modules to 7" intelligent displays with 1024 × 600 resolution and capacitive touch. Ready-made solutions include Lexsystem panel PCs with 7 to 10.4" screens for -20 to 60 °C and AAEON industrial PCs designed as in-vehicle network video recorders (NVR). Apacer industrial SSDs rated for -40 to 85 °C handle data storage.
TE Connectivity rectangular industrial connectors include sealed SUPERSEAL connectors rated IP67. Air quality is measured by calibrated Sensirion SCD30 and SCD4x CO2 sensors and by humidity and temperature sensors with an I2C interface. Ventilation and cooling are provided by ebm-papst 26 V DC radial fans.
Sonitron’s family of THT piezo buzzers has grown to include a modern SMD variant. This latest evolution delivers serious acoustic punch in a compact footprint, maintaining rock-solid performance even in harsh operating environments.
Attend’s new M12 series swaps tedious thread-spinning for a slick push-pull mechanism, slashing your installation times by up to 80%. Crucially, because these connectors strictly conform to the IEC 61076-2-010 standard, you get guaranteed 100% cross-vendor compatibility with zero risk of supplier lock-in.
LCD, OLED, or TFT? Whatever DISPLAY VISIONS display you are planning for your application, you can test it quickly and effortlessly using the manufacturer’s own evaluation boards. Pick one of these three accessible, off-the-shelf boards from our stock and start bench testing straight away.
Our technical specialists will advise you on choosing components. Many products can be requested as samples before ordering, so you can test them in your prototype. Fill in the short form and get a recommendation tailored to your project.
