Product Description

The Keyence PZ-41 is a compact, built-in amplifier photoelectric sensor designed for precise object detection in industrial automation applications. Operating as a diffuse-reflective model, it utilizes an infrared LED light source to detect objects within a specified range of up to 60 cm using a 20 × 20 cm white matte paper reflector. This sensor is engineered for reliable performance, offering features such as adjustable sensitivity, selectable operation modes, and robust environmental resistance. Its compact design and built-in amplifier facilitate easy integration into various systems, making it suitable for applications requiring accurate object detection over a distance.​
