MRVS Series Speed Sensor

GVS Series Speed Sensors

The MRVS speed sensor is engineered to accurately detect the rotational speed and position (teeth and slots) of gears made from ferromagnetic materials. Encased in a durable metallic housing, this sensor employs advanced thin-film magnetoresistive technology. As the gear rotates, variations in the magnetic field alter the electrical resistance of the magnetoresistive element, providing precise detection of gear position and speed.

Features
  • Wide rotation speed detection range, up to 200,000 RPM
  • Durable metallic or plastic housing options available
  • Consistent signal amplitude independent of rotational speed
  • Built-in biasing magnet ensures precise sensing
  • Specifically designed for reliable performance in harsh environments.
  • Operating temperature customizable upon client request, up to 125℃
Applications
  • High-speed and zero-speed detection applications
  • Precision position detection systems
  • Reliable rotation detection in industrial equipment
  • Accurate angular encoder measurement
  • Linear position monitoring solutions
  • Precision PCB hole drilling equipment
  • Computerized flat knitting machines for accurate operational control
