Manufacturer: OMRON
Condition: New and Unused, Surplus.
Overview of Omron E3S-CR11
The Omron E3S-CR11 is an oil-resistant, long-range photoelectric sensor with a metal housing, designed for reliable object detection in harsh industrial environments. It uses a retro-reflective sensing method with a built-in MSR (Mutual Interference Prevention) function to prevent interference from other sensors. The sensor has a sensing distance of up to 3 meters using the E39-R1 reflector and features selectable NPN/PNP open collector output and Light-ON/Dark-ON operation modes.
