Rotational speed sensor 907 XP

Hall effectnon-contactexplosion-proof

Explosion Proof Shaft Speed Sensor - Hall Effect Features Square-wave pulse frequency output, NPN open-collector Zero speed operation with no signal loss 5-24 VDC powered Non-contact, large gap distance sensing Bidirectional (quadrature) option Works with Electro-Sensors magnetic pulser discs / wraps Optional Mounting Bracket Assembly and Mounting Magnet Class I, Div I (D) Class II, Div I (E, F, G) Class III XLB-3 enclosure 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.
