Omron E3NC-SH250 2M Smart Laser Photoelectric Sensor
Omron E3NC-SH250 2M is a smart laser sensor head with distance-setting capability across a sensing range of 35 to 250 mm. Its 660 nm red semiconductor laser diode creates the optical source, while the focused spot is approximately 1 mm at a distance of 250 mm. The distance-setting principle allows the sensing position to be established within the specified working range for precise target monitoring. A 2 m pre-wired cable connects the sensor head to associated E3NC equipment, while OUT, STABILITY, and ST indicators provide setup information. Within the E3NC Series, the E3NC-SH250 2M provides the 250 mm distance-setting configuration. Related 250 mm laser sensor heads can be reviewed across the Omron Sensor Range.

The Omron E3NC-SH250 2M Photoelectric Sensor is a smart laser sensor head using distance-setting sensing across a working range of 35 to 250 mm. A 660 nm red semiconductor laser diode provides the optical source, producing an approximately 1 mm spot at a distance of 250 mm. The distance-setting function allows the required sensing position to be established within the specified range. A 2 m pre-wired cable provides the connection to associated E3NC equipment. Orange OUT, green STABILITY, and blue ST indicators provide visual information during setup and operation. Ambient-light resistance is specified at 2,000 lx under incandescent light and 4,000 lx under sunlight. Operating temperature extends from -10 to 55°C, while storage is listed from -25 to 70°C. Humidity is specified from 35% to 85%.
For an Omron distance setting laser sensor requiring a 35 to 250 mm working range, the corresponding model is the E3NC-SH250. Insulation resistance is specified at 20 MΩ minimum at 500 VDC, while dielectric strength is listed at 1,000 VAC for one minute. PBT, PMMA, and PVC are among the stated materials. The model also suits searches for an Omron 250 mm laser sensor and Omron precision distance sensor. Its 1 mm laser spot at 250 mm supports object presence and position sensing where a defined working distance is required. The pre-wired format supports direct connection between the sensing head and associated E3NC equipment. For a related H-version with the same stated 35 to 250 mm sensing range, see E3NC-SH250H 2M.
