FAH52– : 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
Measuring channels can be galvanically isolated in a housing as a voltage signal or current output signal respectively
Reliable rotational direction detection or outage detection and monitoring

Speed sensors of type FAH52 are non-contacting 1- or 2-channel speed encoders with a flange and sensor tube. They measure frequency in accordance with the Hall-effect principle.
