Omron E3JM-DS70M4T-G Photoelectric Sensor
Omron E3JM-DS70M4T-G provides diffuse-reflective sensing up to 700 mm with a 940 nm infrared optical source. The sensing light returns directly from the target surface, allowing the sensor to operate without a separate reflector. Its SPDT relay supports compatible control circuits, while 12 to 240 VDC and 24 to 240 VAC supply compatibility allows installation with different machine power systems. Light-ON or Dark-ON operation can be selected, and the built-in adjustable delay supports timing from 0.1 to 5 seconds. Terminal-block wiring provides the electrical connection. The E3JM-DS70M4T-G forms part of the E3JM Series. Similar relay models can be compared under 700 mm relay sensors across the wider sensing range available from Omron Sensing Products.

The Omron E3JM-DS70M4T-G Photoelectric Sensor provides diffuse-reflective sensing over a distance of up to 700 mm using a 940 nm infrared LED. The emitted light returns directly from the target, allowing object sensing without a separately mounted reflector. Its SPDT relay supports up to 3 A at 250 VAC under the stated resistive-load condition, while supply compatibility covers 12 to 240 VDC and 24 to 240 VAC at 50/60 Hz. Terminal-block wiring provides the electrical interface. Light-ON or Dark-ON operation can be selected, and a one-turn adjuster supports sensitivity setting. An adjustable timer from 0.1 to 5 seconds provides control over the relay switching sequence. Operate or reset time is specified at 30 ms max., and power consumption is listed at 2 W max. The G-version format provides an alternative wiring arrangement within the same sensing group.
For an Omron 700 mm timer photoelectric sensor requiring relay output and broad AC/DC voltage support, the corresponding model is the E3JM-DS70M4T-G. Its adjustable timer provides delayed switching while retaining the same infrared diffuse-reflective sensing principle. The specification also suits searches for an Omron diffuse relay sensor and Omron multi voltage timer sensor. Operating temperature extends from -25 to 55°C, while sensitivity can be set with the one-turn adjuster. For the closely related timer-equipped 700 mm model without the G designation, see E3JM-DS70M4T.
