Omron E3Z-L61 2M Photoelectric Sensor
Omron E3Z-L61 2M is a narrow-beam diffuse-reflective photoelectric sensor designed around a specified sensing distance of 90 ±30 mm. Its 650 nm red LED produces a concentrated optical path toward the target, supporting object sensing where a narrower working area is useful. The NPN output communicates the switching state to compatible industrial control circuitry, while Light-ON or Dark-ON operation can be selected according to the required machine logic. The sensor operates from 12 to 24 VDC and includes a 2 m pre-wired cable. Current consumption is specified at 30 mA maximum, response time at 1 ms maximum, and a one-turn adjuster supports sensitivity setting. Within the E3Z Series, the E3Z-L61 2M provides narrow-beam sensing within the compact diffuse sensor range across Omron Automation Products.

The Omron E3Z-L61 2M Photoelectric Sensor uses narrow-beam diffuse-reflective sensing around a specified 90 ±30 mm working distance. Its 650 nm red LED produces a concentrated optical path toward the target, supporting sensing where a narrower optical area is required. The NPN output communicates the switching state to compatible industrial control circuitry, while 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 2 m pre-wired cable. Current consumption is specified at 30 mA maximum, operate or reset time is 1 ms maximum, and a one-turn adjuster supports sensitivity setting. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight.
For an Omron narrow-beam diffuse sensor requiring NPN output and a compact working zone, the applicable model is the E3Z-L61. Operating temperature extends from -25 to 55°C, while storage covers -40 to 70°C without icing or condensation. Insulation resistance is specified at 20 MΩ minimum at 500 VDC, and dielectric strength is 1,000 VAC for one minute. Reverse supply polarity, output short-circuit, mutual-interference, and reversed-output polarity protection are included. PBT is listed as the housing material, while IP67 enclosure protection is stated. Its specification also suits searches for an Omron narrow beam sensor and Omron NPN diffuse photoelectric sensor. For a shorter-range limited-reflective E3Z model with a 30 ±20 mm working zone, see the E3Z-L63 2M.
