SPEED SWITCH is a non-contact type motion sensor to detect the revolving speed of machinery shaft and operates output relay when the speed reaches setting value.

Speed Switch is applicable to confirm if a mechanical shaft, which rotates in extra-low speed as typified by“ sending roller of reheat furnace”,“low speed agitator or thickener” ,etc.,rotates in proper speed.

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.
