The Omron E3ZM-R86 is a compact retroreflective photoelectric sensor equipped with mutual interference suppression (MSR) to ensure stable and accurate detection in environments with multiple sensors. It supports a sensing range of up to 4 meters and uses a reliable infrared LED (870 nm) for consistent performance across varying object surfaces. Designed with a PNP output configuration and a standard M8 connector, this sensor runs on a 10 to 30 VDC power supply and is optimized for fast and simple integration into control panels and automation setups.
With a 1 ms response time and user-selectable Light-ON/Dark-ON modes, the sensor supports high-speed operations and flexible use across applications. It includes a one-turn sensitivity adjuster and dual indicators for operation and stability, enabling real-time diagnostics and reduced maintenance overhead. Advanced protection circuits—covering reverse polarity, short-circuit, and reversed output polarity—enhance long-term operational reliability. This makes the E3ZM-R86 a trusted choice for high-cycle automation lines, especially in logistics, packaging, and material handling sectors.
Encased in a SUS316 stainless steel housing and built with durable materials like methacrylic resin, PEEK, PES, and fluoro rubber, the Omron E3ZM-R86 is rated IP67 and IP69K, ensuring protection from dust, water, and high-pressure cleaning. Its mechanical and environmental resilience, paired with Omron's trusted engineering, makes this sensor a reliable solution for long-range industrial object detection.
