Technical Overview

The Omron E3Z-D81 2M is a general-purpose, compact diffuse-reflective photoelectric sensor with a built-in amplifier. Designed for reliable non-contact object detection, it features a 5 to 100 mm sensing range and utilizes an infrared LED (860 nm) light source. Housed in a durable thermoplastic P.B.T. enclosure with an IP67 and IP69K rating, it is highly resilient against water washdowns and dust, making it ideal for harsh industrial environments. The sensor operates on a 12 to 24 VDC supply, providing a versatile PNP open-collector output with selectable Light-ON/Dark-ON modes and a rapid 1 ms response time. It is pre-wired with a 2-meter cable for direct integration into automation control systems.
