Keyence PZ-G101EN Photoelectric Sensor

Keyence PZ-G101EN Photoelectric Sensor delivers fast, reliable object detection in industrial environments with a diffuse-reflective, narrow-view sensing mode. It is commonly installed in packaging machines, conveyors, and automated assembly lines to enable accurate presence sensing and position verification, and it’s a common replacement or retrofit choice for improving detection reliability in automation systems. As part of the PZ-G Series, this sensor uses diffuse-reflective sensing, features a red LED light source, and provides an NPN open-collector output (30 V max, 100 mA max). It operates from 10–30 V DC, with an M12 connector (pigtail), and offers IP67/IP69K protection, along with an operating temperature range of -20 to +55 °C. The detection distance is up to 200 mm, and the response time is 500 µs. Common replacements include the Keyence PZ-G102EN, PZ-G41EN, and PZ-G42EN.
