HaslerRail speed sensors have been found in all kinds of rail vehicles for more than a century. Rail vehicles are equipped with speed, direction and distance detection systems to ensure safe and visible operation on today’s busy, centrally supervised networks. HaslerRail offers a comprehensive range of products to satisfy the most demanding detection requirements and applications. In addition to traditional pulse generators and hall effect sensors we also include non-contact speed and distance sensors, so-called True Speed Over Ground Sensors:

The optical CORRail sensor offers contactless, track-bed independent, direct measurement of a rail vehicle’s speed and operating direction, using the railhead as a reference.

The DOPRail radar sensor measures the vehicle speed over ground using the Doppler effect.
