Omron E3JM-DS70M4-G Photoelectric Sensor
Omron E3JM-DS70M4-G provides diffuse-reflective sensing over distances up to 700 mm using a 940 nm infrared LED. Light reflected directly from the target returns to the sensor, allowing short-to-medium range object sensing without a separate receiver. The SPDT relay supports compatible industrial control circuits, while the sensor accepts 12 to 240 VDC or 24 to 240 VAC at 50/60 Hz. Light-ON or Dark-ON operation can be selected, and ON-delay, OFF-delay, or one-shot timing is available. Terminal-block wiring and the specified conduit arrangement support machine installation. The E3JM-DS70M4-G belongs to the E3JM Series. Related relay models can be explored under AC DC diffuse sensors across the wider range from Omron Relay Sensors.

The Omron E3JM-DS70M4-G Photoelectric Sensor provides diffuse-reflective sensing over a maximum distance of 700 mm when referenced to a 200 × 200 mm white target. Its 940 nm infrared LED sends light toward the object, and the returned light level operates the SPDT relay output. The sensor supports 12 to 240 VDC and 24 to 240 VAC at 50/60 Hz, allowing use with different control-voltage arrangements. Relay capacity reaches 3 A at 250 VAC under the specified resistive-load condition. Light-ON or Dark-ON operation can be selected according to the required switching logic, while a one-turn adjuster supports sensitivity setup. ON-delay, OFF-delay, and one-shot modes provide additional timing control. Operate or reset time is specified at 30 ms max., and terminal-block wiring with the G-version conduit arrangement provides the electrical connection.
For an Omron AC DC diffuse photoelectric sensor requiring 700 mm sensing, relay switching, and selectable timing modes, the corresponding model is the E3JM-DS70M4-G. Its broad input range supports several machine power systems, while the infrared source allows the target itself to return the sensing light. The specification also matches searches for an Omron 700 mm relay sensor and Omron infrared diffuse sensor. Operating temperature extends from -25 to 55°C, while the one-turn sensitivity control supports setup across different target conditions. For the related E3JM model offering the same 700 mm diffuse-reflective sensing without the G-version designation, see E3JM-DS70M4.
