Omron E3Z-L61 0.5M Photoelectric Sensor
Omron E3Z-L61 0.5M is a diffuse-reflective photoelectric sensor designed for direct object sensing across a range from 20 to 200 mm. Its 670 nm red LED directs light toward the target, while the returned optical signal is evaluated by the sensor without requiring a separate reflector. The NPN output transfers the switching state to compatible machine-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 0.5 m pre-wired cable for short connection runs. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. Within the E3Z Series, the E3Z-L61 0.5M provides a compact option for short-range diffuse sensors across Omron Industrial Sensor Products.

The Omron E3Z-L61 0.5M Photoelectric Sensor uses diffuse-reflective sensing across a specified 20 to 200 mm working range. Its 670 nm red LED sends light toward the target, while the returned optical signal is evaluated directly by the sensor without requiring a separate reflector. The NPN output communicates the switching state to compatible machine-control circuitry, and Light-ON or Dark-ON operation can be selected according to the required logic. The sensor operates from 12 to 24 VDC and includes a 0.5 m pre-wired cable. 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 configuration.
For an Omron diffuse-reflective sensor requiring NPN output and a 20 to 200 mm working range, the relevant model is the E3Z-L61. Direct target-return sensing avoids the need for a separate reflector and supports close-range object presence sensing. The 12 to 24 VDC operating range suits common DC control equipment, while selectable switching logic supports different machine sequences. The supplied specification states IP67 enclosure protection. Its configuration also matches searches for an Omron 200 mm diffuse sensor and Omron red LED photoelectric sensor. The short 0.5 m cable is useful where control wiring is close to the sensing point. For the same 20 to 200 mm configuration with a longer 5 m cable, see the E3Z-L61 5M.
