FAHU52–Three-/four-channel speed sensor Hall-effect in 2-hole flange design : NORIS Group GmbH

Typical applications: Rail Technology (Light & Heavy Rail) and Special Machinery (Mining)
Frequency measurement with ferromagnetic scan objects using the Hall-effect principle
Lifecycle-cost optimised: Wear- and maintenance-free due to non-contact scanning, high durability due to robust design
Robust design for risk-free installation and extreme environmental conditions
Well-suited for safety applications, e.g., fire protection according to EN 45545
Up to 4 measuring channels can be galvanically isolated in a single housing. Voltage signals or current output signals can be featured in any combination.

Type FAHU52 speed sensors are non-contacting three- or four-channel speed sensors with a stainless-steel flange and sensor tube. They measure frequency in accordance with the Hall-effect principle. They acquire the speed of ferromagnetic objects, e.g., toothed wheels with various tooth shapes, screw heads, bore holes, apertures, grooves or pulse bands on smooth shafts (accessories). Their compact and robust design, as well as the relevant tests as per DIN EN 50155, make them ideal for applications in the field of transport technology, e.g., measuring speed at the traction motor, gearbox or wheel set. The sensors are available with different output signals (voltage or current output).
