The KEYENCE PZ-G61CP is a long-range retro-reflective photoelectric sensor engineered for precise presence detection in industrial automation. Its compact rectangular housing, robust build, and high optical performance make it ideal for conveyors, packaging machinery, intralogistics, and general machine building where reliable triggering and minimal maintenance are essential.

Featuring a PNP open-collector output and an M8 connector, the PZ-G61CP operates from 10 to 30 VDC and delivers a 0.1 to 4.2 m sensing range when used with an R-2L reflector. A high-visibility red LED emitter, selectable Light-ON/Dark-ON modes, and a 230° one-turn sensitivity trimmer streamline commissioning, while a fast 500 µs response keeps pace with high-throughput processes. Built-in reverse-polarity and overcurrent protection, surge absorption, and interference suppression with automatic frequency shifting for up to two units ensure stable performance; the reinforced PBT housing with PMMA lens cover meets IP67, NEMA 4A/6/12, and DIN IP69K for washdown and harsh environments, and operates from -20 to +55 °C.

By standardizing detection across lines and simplifying setup, this sensor helps reduce downtime and total cost of ownership, and it comes with a 1-year warranty to support confident deployment.
