Omron E3Z-L61 5M Photoelectric Sensor
Omron E3Z-L61 5M is a diffuse-reflective photoelectric sensor for direct object sensing across a specified 20 to 200 mm range. Its 670 nm red LED directs light toward the target, while the returned optical signal establishes the switching state without requiring a separate reflector. The NPN output communicates this state to compatible industrial control equipment, while selectable Light-ON and Dark-ON operation supports different machine logic. The sensor operates from 12 to 24 VDC and includes a 5 m pre-wired cable for extended connection length. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. Within the E3Z Series, the E3Z-L61 5M provides longer wiring for red LED diffuse sensors across the Omron Sensor Range.

The Omron E3Z-L61 5M Photoelectric Sensor uses diffuse-reflective sensing across a specified 20 to 200 mm range. Its 670 nm red LED directs light toward the target, while the returned optical signal is evaluated directly by the sensor to establish the switching state. The NPN output communicates this state to compatible industrial control circuitry, while selectable Light-ON and Dark-ON operation supports different control requirements. The sensor operates from 12 to 24 VDC and includes a 5 m pre-wired cable for extended wiring. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. PBT and denatured polyarylate are listed as construction materials for this compact square sensor.
For an Omron diffuse sensor requiring NPN output, a 20 to 200 mm working range, and longer fixed wiring, the relevant model is the E3Z-L61. Direct target-return sensing eliminates the requirement for a separate reflector, while selectable switching logic supports different machine sequences. The 12 to 24 VDC supply range suits common industrial control systems, and the supplied specification states IP67 enclosure protection. This configuration also matches searches for an Omron 5 m cable sensor and Omron 200 mm diffuse photoelectric sensor. The longer cable provides additional routing distance between the sensing point and control wiring. For the same stated 20 to 200 mm range with a shorter 0.5 m cable, see the E3Z-L61 0.5M.
