Series 18 Shaft Speed Sensors

The new Electro-Sensors Series 18 speed sensors are available in a range of output sensing and signaling options to meet even the most demanding application requirements. The sensors function by detecting passing magnets from a shaft-mounted pulser disc or wrap and output a voltage pulse frequency proportional to the shaft rotation speed. All models operate down to (and including) zero speed. Series 18 sensors are compatible with PLC inputs, tachometers and a wide range of frequency meters.
