906 Hall Effect Sensor
The 906 standard Hall-effect sensor produces a digital pulse signal for use with speed switches, tachometers, counters, signal conditioners, or can be used as a direct pulse generator.
As a pulser disc or split collar wrap (mounted on the monitored shaft) rotates, the target magnets pass in front of the sensor. The Hall-effect sensor switches high and low as it is exposed to the alternating polarity of the magnets on the disc or wrap, producing a digital pulse output.
The recommended gap distance between the sensor and pulse generator is 1/4 inch +/- 1/8 inch. The gap flexibility makes the sensors tolerant of vibration, slight shaft run-out, minor misalignment, and other industrial elements. Model #906 sensors are water-proof and suitable for most applications, including environments where dirt, dust, grease, or moisture are present.
906 sensors can be mounted up to 1500 feet from the control unit – speed switch, tachometer, etc. They are powered by 5-25 Vdc and provide an NPN Open Collector output. The 906 standard sensor has a threaded aluminum body, and is supplied with a mounting bracket. These sensors are also available in a stainless steel body.
The 906 Hall-effect Sensor is the standard sensor for most Electro-Sensors systems.
