Equipped with a setup and beam alignment system, the PZ-G series of self-contained, threaded photoelectric sensors from Keyence offers higher detection distances of up to 40 meters, faster response times, and easier installation than conventional sensors. The high power and long range of the sensors, combined with response speeds of up to 500 µs, provide the type of performance needed for reliable, stable detection in high-speed production and assembly-line applications.
The PZ-G series gives you a choice of standard M8 and M12 threaded quick-connects with a standard pin-out for fast, easy interchangeability. It also offers three sensing styles: thru-beam, reflective, and retro-reflective. The PZ-G52 high-power thru-beam type has four times the detecting distance with two times the response speed of other models. Model PZ-G51, a four-element red LED type thru-beam, offers a 30-meter detecting distance with twice the response speed of conventional models. The PZ reflective type includes three models, and the retro-reflective type includes the PZ-G61, a 4.2-meter range sensor.
To simplify installation, setup, and alignment, the PZ-G incorporates a front-panel LED alignment indicator that illuminates when the transmitter beam is perfectly aligned with the receiver. A one-touch mounting bracket eliminates the need for mounting screws. Simply insert the sensor body into the bracket and push down on a sliding sensor holder until it clicks to firmly mount the senor. Keyence offers 19 types of mounting brackets, including the one-touch model, to accommodate a wide range of mounting requirements.
