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
