rotational speed sensor / magnetic / pick-up
Type of movement:
Min.: -54 °C (-65.2 °F)
Max.: 120 °C (248 °F)
MP series magnetic pickups are used with tachometers, speed switches and engine controls to give accurate and reliable measurement of engine speed. The pickup is typically mounted through an engine housing in close proximity to flywheel or gearwheel teeth. The rotation of the metal gear-teeth past the pickup head induces an AC voltage. The AC signal frequency, which is proportional to engine speed, can be measured by suitable instruments or control devices.
