Speed Sensors for Detecting Magnets

Digital Hall Effect speed sensors provide an output that switches when detecting a magnetic field passing the face of the sensor. When connected to a tachometer, they can measure the rotational or linear speed of the target the magnets are attached to. Quadrature Sensors as well as Speed and Direction Sensors provide two outputs so that you can resolve both speed of the target and the direction of movement.

Magnetic speed sensors in our catalog include options for detecting the following:

  • South Pole Magnetic Field Detection
  • Either Pole Magnetic Field Detection
  • Dual Outputs (one South Pole and one North Pole)
  • Quadrature and Speed/Direction Outputs for detecting direction of movement
  • High sensitivity, Low Sensitivity, and Custom Switch Point programmed Sensors
  • Latching outputs for creating 50% duty cycles with alternating pole magnets

A large variety of target magnet options are available in our Accessory Catalog
