The Omron E3S-CR11 2M is a rugged photoelectric sensor built for demanding industrial environments. Utilizing a retro-reflective sensing method, it detects targets up to 3 meters away using a red LED light source (660 nm) in combination with a standard reflector. This model is ideal for object detection in systems where space constraints or environmental exposure would make through-beam setups impractical.
Operating on 10 to 30 VDC (with 10% ripple), the E3S-CR11 2M offers a selectable NPN/PNP open collector output, supporting up to 100 mA of load current. The output can be configured in either Light-ON or Dark-ON mode, allowing system designers flexibility in logic design. With a fast response time of 1 ms max. and a one-turn sensitivity adjuster, it provides quick and stable switching for high-speed automation equipment.
This sensor is built with resilience in mind. It consumes only 40 mA max. and includes built-in protection circuits for reverse polarity, output short-circuit, and mutual interference prevention. Itβs designed to function in tough indoor environments, tolerating incandescent light up to 5,000 lx and sunlight up to 10,000 lx. Operating temperature ranges from β25Β°C to 55Β°C, with storage rated down to β40Β°C and up to 70Β°C.
Mechanically, the E3S-CR11 2M passes vibration resistance tests (10β2,000 Hz, 1.5-mm amplitude) and shock resistance up to 1,000 m/sΒ² in all three axes. The housing meets IEC IP67 and NEMA 6P (indoor use only) standards, and is tested in oil-resistant conditions under Omronβs in-house validation.
Common applications include conveyor lines, parts detection, material handling, and packaging systems in automotive and food processing industries. The Omron E3S-CR11 2M offers a durable, oil-resistant sensing solution with flexible output options and fast response, making it a dependable choice for automation integrators.
