Speed Sensor & Rotary Encoder Products
We can fulfill your requirements fast and cost-effectively, either from our wide range of products or as a custom-made solution.
Robust and Reliable Pulse Encoders for Harsh Rail Environments
Encoders used in rail vehicles are always exposed to very extreme conditions. They need to be unaffected by dirt, oil and grease, rainwater, condensation, and high and/or fluctuating temperatures. Rail vehicles are also subject to considerable shocks and vibrations, particularly in the unsprung parts of bogies. Our encoders can also take this kind of punishment without damage.
Our encoders operate magnetically. They employ the very latest sensor technology, circuitry and construction techniques and can therefore offer a high level of electrical and mechanical robustness, guaranteeing reliable function and long-term dependability.
Rail Vehicle Speed Sensors
Speed sensors for sensing toothed wheel targets are available in a wide range of types. Almost any installation requirement can be accommodated with different cable and connectors.
