Keyence offers PZ-G photoelectric sensors

A Keyence (UK) product story
Edited by the Engineeringtalk editorial team Nov 26, 2008

Keyence UK has announced the PZ-G series of self-contained, threaded, high-power photoelectric sensors that can provide detection distances of up to 40m and high response speeds.

The PZ-G features standard M8 and M12 threaded quick-connects with a standard pin-out for fast and easy sensor interchangeability.

The high power and long range of PZ-G sensors, combined with response speeds of up to 500 usec, provide the type of performance demanded for reliable, stable detection in high-speed production and assembly line applications.

The PZ-G incorporates an LED alignment indicator that illuminates brightly when the transmitter beam is perfectly aligned with the receiver.

Perfect sensor beam alignment is instantly confirmed.

The alignment LED is also a useful maintenance and trouble-shooting feature.

A newly designed one-touch mounting bracket eliminates the need for mounting screws and saves time.

The user inserts the sensor body into the bracket and pushes down on a sliding sensor holder until it clicks to firmly mount the sensor.

19 types of mounting brackets, including the one-touch model, are available for a range of mounting requirements.

The PZ-G series model line-up includes three sensing styles: thrubeam, reflective and retro-reflective, to meet all application needs.

The PZ-G52 high-power thrubeam 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 thrubeam, offers a 30m 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 4.2m range sensor.

Interference suppression prevents interference from nearby sensor units.

Bipolar PNP + NPN outputs are compatible with any input device.

A PRO (Polarised Reflection Optics) function in the retro-reflective model eliminates reflections from metallic or mirror-surfaced targets, enabling reliable detection of metallic targets.

Additionally, the PZ-G includes a patented DEX (Difference Expansion) function that amplifies light attenuation caused by transparent targets, therefore guaranteeing stable detection.
