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.
