907 XP sensors are used in applications requiring hazardous location ratings, or in applications where the sensor may be subject to abuse. It has a 1-inch NPT conduit opening for wiring, terminal strip for wiring, and is provided with a mounting bracket and 10 ft of cable. The quadrature (bidirectional) option has two sensors and is designed for applications requiring both speed and direction information. Specify vertical alignment when the magnets will pass vertically in front of the sensor face, and horizontal alignment when the magnets will pass horizontally in front of the sensor face.
These speed sensors use magnet-sensing Hall Effect IC's to produce a digital pulse signal to interface with speed switches, tachometers, counters, signal conditioners, or PLC's. Hall Effect sensors provide true zero speed operation with square-wave output and immunity to electrical noise.
A pulser disc or split collar pulser wrap with embedded magnets is mounted on the monitored shaft. As the shaft rotates, the magnets pass in front of the sensor causing the sensor to switch high and low, thus producing a digital pulse output. The sensors provide a digital square wave signal with a 50/50 duty cycle when used with pulse generators that have evenly spaced magnets of alternating polarity, such as Electro-Sensors Model 255 Pulser Disc. 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, shaft run-out, misalignment, and industrial environments.
