Product Description

​The Omron E3S-CR61-M1J is a robust, oil-resistant, retroreflective photoelectric sensor designed for long-range detection in industrial environments. Encased in a durable metal housing, it offers a sensing distance of up to 3 meters when used with the E39-R1 reflector, making it suitable for applications requiring precise and reliable object detection over extended ranges. The sensor features selectable NPN or PNP output configurations and supports both Light-ON and Dark-ON operation modes, providing flexibility to accommodate various system requirements.
