The Electro-Sensors HE950 gear tooth sensor monitors gear teeth and other ferrous metal targets. The HE950 gear tooth sensor produces digital pulse signals for use with speed switches, tachometers, counters, signal conditioners, or as a direct pulse input into programmable controllers (PLCs). It incorporates a dual Hall Effect sensor and signal processing that switches in response to differential magnetic signals created by a ferrous target. Typical targets are gear teeth, keyways, or bolt heads, and the circuitry achieves true zero-speed operation down to zero Hz. Each sensor is entirely solid state with no moving parts to wear out, providing a low maintenance rugged and long-lasting sensor.
The HE950 sensors are powered by 5-24 VDC, provide an NPN open collector output and can be mounted up to 1,500 feet from the control unit. The standard HE950 sensor has a threaded aluminum, NEMA 4 housing and is supplied with an adjustable, plated-steel mounting bracket and 10 feet of 3-conductor shielded cable.
