ISO9001 Certified Customizable Hall Speed Sensor
The Hall-type speed sensor uses magnetic induction to measure speed contactlessly. It is wear-resistant, highly accurate, and highly anti-interference. It can adapt to the harsh environment of rail transit and is used in key parts such as axles and motors to ensure safe and reliable operation.
Product Features
· Non-contact measurement – Operates via magnetic field sensing, eliminating mechanical wear for extended service life.
· High-precision response – Detects minute speed variations with real-time signal output for critical control systems.
· Robust environmental resilience – Withstands extreme temperatures, vibration, and moisture in demanding rail operating conditions.
· EMC-compliant reliability – Provides stable output with superior electromagnetic interference (EMI) immunity for fail-safe operation.
