Omron E3JM-DS70M4-US Photoelectric Sensor
Omron E3JM-DS70M4-US is a diffuse-reflective photoelectric sensor with a sensing distance of up to 700 mm using a 940 nm infrared LED. The target surface returns the emitted light toward the sensor, allowing operation without a separate reflector or receiving unit. Its SPDT relay is rated up to 3 A at 250 VAC under the stated conditions, while the wide supply supports 12 to 240 VDC and 24 to 240 VAC. Light-ON and Dark-ON modes are selectable, and terminal-block wiring provides the electrical interface. A one-turn adjuster supports sensitivity setting. The E3JM-DS70M4-US is part of the E3JM Series. Similar configurations can be reviewed under relay output diffuse sensors across the wider range available through Omron Industrial Sensors.

The Omron E3JM-DS70M4-US Photoelectric Sensor provides diffuse-reflective sensing up to 700 mm using a 940 nm infrared LED when referenced to a 200 × 200 mm white target. The sensor evaluates light returned directly from the object, so a separate reflector is not required for the sensing arrangement. Its SPDT relay is rated up to 3 A at 250 VAC under the stated conditions. Supply compatibility covers 12 to 240 VDC and 24 to 240 VAC at 50/60 Hz, while terminal-block wiring provides the electrical connection. Light-ON or Dark-ON operation can be selected according to the required control response. A one-turn adjuster supports sensitivity setup, and ON-delay, OFF-delay, or one-shot modes provide timing flexibility. Operate or reset time is specified at 30 ms max., while power consumption is listed at 2 W max.
For an Omron diffuse relay photoelectric sensor requiring 700 mm sensing and broad AC/DC voltage compatibility, the corresponding model is the E3JM-DS70M4-US. Its infrared source supports direct target sensing, while the relay interface provides switching for compatible control circuits. The specification also suits searches for an Omron 700 mm diffuse sensor and Omron terminal block photoelectric sensor. Operating temperature extends from -25 to 55°C, and selectable timer modes provide control over the switching sequence. For a related E3JM 700 mm diffuse-reflective version with the standard model designation, see E3JM-DS70M4.
