Pulse generators are converting an axle’s rotational motion into an electrical signal, which can be used to measure and record speed and distance, sense wheel slip and slide for different control and safety functions. Pulse generators are inherently safe, and are suitable for use in SIL4 systems.

HaslerRail is continuously improving its pulse generators and the latest technology has been employed in the design to make it suitable for the most extreme mechanical and thermal stress. Thanks to a wide range of different mechanical adapters and signal output options, this product can be customized to cover any project specific requirements.

Our pulse generators are built on an optical system that operates in the infrared range. It is possible to generate two different frequencies with independent electrically-isolated sensors. And, because they offer unparalleled accuracy and reliability, our pulse generators can be used in ETCS and other signalling applications.
