Speed Relay is a mechanical type motion sensor for monitoring operation speed of belt conveyors, cranes, crushers, etc., and operates when speed of the machine shaft becomes the setting speed. Since the microswitch in Speed Relay is mechanically turned ON or OFF by induction torque generated by rotation of the permanent magnet, the power supply is not necessary. Besides, the maintenance is easy.
