Omron E3S-R66 | Omron Retro-Reflective Photoelectric Sensor NPN
Overview
Description The Omron E3S-R66 is a retro-reflective photoelectric sensor with M.S.R. function designed for object detection in industrial automation systems. It operates on 10 to 30 VDC and provides an NPN open-collector output. The sensor supports a sensing distance of 0.1 to 1 meter when used with a compatible reflector. Technical Specifications Condition New/Never Used Surplus Brand Omron Category Sensors & Switches Part Number E3S-R66 Subcategory Photoelectric Series E3S Sensing Method Retro-Reflective with M.S.R. Sensing Distance 0.1 m to 1 m (with reflector) Light Source Red LED (660 nm) Supply Voltage 10–30 VDC Output Type NPN Open Collector Max Output Rating 30 VDC, 100 mA Response Time 1 ms max Operating Temperature 0°C to +40°C Protection Rating IP67 Connection Method M12 Connector Weight 0.13 lbs Information About E3S-R66 The E3S-R66 belongs to the Omron E3S series of square-type photoelectric sensors. It uses a red LED light source (660 nm) and a retro-reflective sensing method with M.S.R. functionality for stable detection performance. The unit features selectable Light-ON/Dark-ON operation and incorporates output short-circuit and reverse polarity protection. Designed with an IP67-rated housing and M12 connector interface, it is suitable for industrial environments requiring reliable object sensing. Key Features: Retro-Reflective Sensing: Detects objects using reflector-based light return. Sensing Range 0.1–1 m: Effective detection with compatible reflector. Red LED Light Source: 660 nm visible light emission. NPN Open-Collector Output: Rated 30 VDC max, 100 mA max. 10–30 VDC Supply Voltage: Compatible with standard industrial DC systems. Selectable Light-ON/Dark-ON Mode: Configurable output operation. IP67 Protection Rating: Dust-tight and water-resistant enclosure. M12 Connector Interface: Secure industrial connection method. The E3S-R66 delivers the reliability and precision required for retro-reflective object detection in industrial automation systems.
