Omron E3S-5E41 Photoelectric Sensor
Omron E3S-5E41 is a through-beam photoelectric sensor with a built-in amplifier for object sensing across a maximum distance of 5 m. A 950 nm infrared LED establishes the optical path between separate emitter and receiver units, while the switching state changes when an object interrupts the beam. The sensor operates from 12 to 24 VDC, consumes up to 50 mA, and uses a pre-wired cable for connection. Light-ON or Dark-ON operation can be selected, and response time is specified at 3 ms. Red light and green stability indicators provide visual operating information. Within the E3S Series, the E3S-5E41 provides the 5 m infrared configuration. Related long-range through-beam sensors can be reviewed across Omron Automation Sensors.

The Omron E3S-5E41 Photoelectric Sensor uses through-beam sensing with a built-in amplifier across a maximum distance of 5 m. Its 950 nm infrared LED provides the optical path between separate emitter and receiver units, while the switching state changes when an object interrupts the beam. The sensor operates from 12 to 24 VDC and uses a pre-wired cable for electrical integration. Current consumption is specified at 50 mA maximum, with 25 mA assigned to the emitter and 25 mA to 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 response time is specified at 3 ms maximum. Red light and green stability indicators provide setup and operating information.
For an Omron long range through beam sensor requiring a 5 m optical path and infrared light source, the corresponding model is the E3S-5E41. The stated sensing target is an opaque object with a minimum diameter of 11 mm. Operating temperature extends from -25 to 55°C, while storage is specified from -40 to 70°C without icing or condensation. Ambient-light resistance reaches 10,000 lx under sunlight. Zinc die-cast, polycarbonate, and iron are among the listed materials. The specification also aligns with searches for an Omron 5 m photoelectric sensor and Omron pre wired through beam sensor.
