Leuze PRK318B/4P‑M12

Leuze PRK318B/4P‑M12 | Retro-Reflective Photoelectric Sensor | 0.1–5 m | Polarized Red Light | M12 Connector

Overview

The Leuze PRK318B/4P‑M12 is a polarized retro-reflective photoelectric sensor with a 5 m sensing range and a visible red light beam. Housed in a robust M18 cylindrical body with an M12 connector, this sensor is optimized for reliable object detection, including on shiny or reflective surfaces. It features a PNP switching output and is well-suited for general-purpose industrial automation applications.
