Product Specs

The OMDC-MPU-A geartooth pick-up provides speed sensing capabilities using an integrated hall-effect sensor in conjunction with a permanent magnet which supplies a bias field. This ready-to-use pick-up directly senses rotating ferrous gear and other similar gear-type targets. The OMDC-MPU-A Series is capable of sensing various target tooth sizes over wide ranges of airgap. The operational airgap achieved is independent of gear rotation speed. The small module size makes it ideal in applications where space considerations are of concern. The rugged design allows the operation of these sensor assemblies in hostile environments where dirt and oil are major problems.

Operating Temperature: -40 to 125°C (-40 to 257°F)
Input Volgate: 4.5 to 24 Vdc
Output: NPN open collector output– sinking up to 20 mA
Connection: 3-wire 22 AWG with stripped leads 1 m (40') long
Mounting: Can be mounted in any orientation
Material: Cylindrical aluminum housing
Dimensions: 25.4 mm L (1') x 11.9 mm diameter (15/32')

For installation and wiring instructions... see 'Specs' above for details.

What is the maximum air gap to the magnet for mounting this sensor?

Asked by: Miken567
Thank you for your question, There really isn’t a MAX spec on this because it depends on target size and material. In practice, set the sensor as close as possible and back away until optimal performance is achieved.

Whether the above sensor be interfaced with Arduino or Raspberry Pi?

Asked by: Harish
Sorry, we have never tested this with Arduino or Raspberry Pi. This device generates a series of pulses proportional to the rate of rotation.
