Omron E3JM-10M4-NN Photoelectric Sensor
Omron E3JM-10M4-NN provides through-beam sensing across a distance of up to 10 m using a 950 nm infrared LED and SPDT relay output. Separate transmitting and receiving units establish the optical path, allowing the relay state to change when an object interrupts the beam. The sensor supports 12 to 240 VDC and 24 to 240 VAC at 50/60 Hz and uses a terminal block for secure electrical wiring. Light-ON or Dark-ON operation can be selected, while ON-delay, OFF-delay, and one-shot delay functions provide additional timing control. Response time is specified at 30 ms max. The E3JM-10M4-NN belongs to the E3JM Series. Related multi-voltage models can be explored under 10 m relay photoelectric sensors across the wider sensing range available from Omron Sensor Products.

The Omron E3JM-10M4-NN Photoelectric Sensor provides through-beam sensing across a distance of up to 10 m using a 950 nm infrared LED and SPDT relay output. Separate transmitting and receiving units establish the optical path, while the relay responds when an object interrupts the transmitted light. The sensor supports 12 to 240 VDC and 24 to 240 VAC at 50/60 Hz and uses a terminal block for electrical connection. Power consumption is specified at 3 W max., divided as 1 W max. for the emitter and 2 W max. for the receiver. Light-ON or Dark-ON operation is switch selectable, while ON-delay, OFF-delay, and one-shot delay functions provide additional timing control. Operate or reset time is 30 ms max., and the SPDT relay is rated up to 3 A at 250 VAC under the specified resistive-load condition.
For an Omron multi voltage through beam sensor requiring 10 m sensing, relay output, and selectable timer functions, the corresponding model is the E3JM-10M4-NN. Its 950 nm infrared source supports long sensing distances, while the terminal-block interface provides secure machine wiring. The specification also suits searches for an Omron 10 m photoelectric sensor and Omron SPDT relay photoelectric sensor. Operating temperature extends from -25 to 55°C, while the sensing target is specified as an opaque object of at least 14.8 mm diameter. For a related E3JM 10 m configuration using the G-NN model designation, see E3JM-10M4-G-NN.
