907 XP (explosion-proof) Hall-effect Sensor
The 907 XP (explosion-proof) 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. The 907 XP sensors are used in applications requiring explosion-proof ratings, or in applications where the sensor may be subject to abuse.
The 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 907 XP sensor has an XLB-3 enclosure which is C.S.A. approved and UL rated for Class I Group D; Class II Group E, F, G; Class III. It has a 1-inch NPT conduit opening, and is provided with a mounting bracket.
The 907 XP Hall-effect sensor is the standard EXPLOSION PROOF sensor for most Electro-Sensors systems.
