Omron E3S-2E41 Photoelectric Sensor
Omron E3S-2E41 is a through-beam photoelectric sensor with a built-in amplifier for sensing objects across a distance of up to 2 m. A 950 nm infrared LED creates the optical path between separate emitter and receiver units, allowing the output state to change when an object interrupts the beam. The sensor operates from 12 to 24 VDC and uses a pre-wired cable for machine connection. Light-ON or Dark-ON operation can be selected, while red light and green stability indicators provide visual operating information. Response time is specified at 3 ms. Within the E3S Series, the E3S-2E41 provides a 2 m through-beam configuration. Related infrared through-beam sensors can be explored across Omron Sensor Products.

The Omron E3S-2E41 Photoelectric Sensor uses through-beam sensing with a built-in amplifier across a maximum distance of 2 m. Its 950 nm infrared LED establishes the optical path between separate emitter and receiver units, and the switching condition changes when an object enters the beam. The sensor operates from 12 to 24 VDC and uses a pre-wired cable for machine connection. Total current consumption is specified at 50 mA maximum, with 25 mA for the emitter and 25 mA for the receiver. Output current is listed from 1.5 to 4 mA, while load current is rated up to 80 mA. Light-ON or Dark-ON operation is selectable, and operate or reset time is specified at 3 ms maximum. Red light and green stability indicators provide status information.
For an Omron infrared through beam photoelectric sensor requiring a 2 m working distance and pre-wired connection, the corresponding model is the E3S-2E41. The stated target is an opaque object with a minimum diameter of 7 mm. Operating temperature extends from -25 to 55°C, with storage from -40 to 70°C without icing or condensation. Ambient-light resistance reaches 10,000 lx under sunlight. Insulation resistance is specified at 20 MΩ minimum at 500 VDC, while dielectric strength is 1,000 VAC for one minute. Its specification also matches searches for an Omron 2 m infrared sensor and Omron built-in amplifier sensor. For a related E3S through-beam model within the same 2 m sensing group, see E3S-2E4.
