FAH52–One/two-channel speed sensor Hall-effect in 2-hole flange design : NORIS Group GmbH

Typical application areas: railway technology (light & heavy rail) and special machine construction (mining)
Frequency detection on ferromagnetic scanning objects according to the Hall principle
Lifecycle cost optimized: wear and maintenance-free through contactless scanning, high durability through robust design
Robust design for risk-free installation and harsh environmental conditions
Good suitability 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 direction detection or standstill 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.
