Omron E3Z-LS61-UL 2M Photoelectric Sensor
Omron E3Z-LS61-UL 2M is a distance-settable photoelectric sensor using background suppression across a specified 20 to 200 mm sensing range. Its 670 nm red LED supplies the optical source, while the BGS principle helps separate the intended target from surfaces positioned beyond the selected sensing point. The NPN open-collector output transfers 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, response time at 1 ms maximum, and a five-turn endless adjuster supports precise setting. Within the E3Z Series, the E3Z-LS61-UL 2M provides adjustable NPN sensing within the distance-settable sensor range across Omron Sensing Range.

The Omron E3Z-LS61-UL 2M Photoelectric Sensor uses distance-settable sensing with background suppression across a specified 20 to 200 mm working range. Its 670 nm red LED provides the optical source, while the BGS principle helps separate the intended target from surfaces positioned beyond the selected sensing point. The NPN open-collector output supports a load supply voltage up to 26.4 VDC and load current up to 100 mA. 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 five-turn endless adjuster supports precise setting.
For an Omron distance-settable sensor requiring NPN output, background suppression, and precise adjustment across a 20 to 200 mm range, the applicable model is the E3Z-LS61-UL. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -25 to 55°C, while storage covers -40 to 70°C without icing or condensation. Reverse supply polarity, output short-circuit, and mutual-interference protection are included. The five-turn endless adjuster provides finer setting than the one-turn arrangement listed for the standard 2 m version. Its specification also suits searches for an Omron adjustable BGS sensor and Omron NPN distance-settable photoelectric sensor. For the standard E3Z-LS61 version using a one-turn adjuster and 2 m cable, see the E3Z-LS61 2M.
