Omron E3RB-DP11 2M Photoelectric Sensor
Omron E3RB-DP11 2M is a PNP diffuse-reflective photoelectric sensor designed for direct object sensing across a short 100 mm distance. Its red LED directs light toward the target, while the returned light provides the sensing information used to switch the PNP output. The sensor operates from 10 to 30 VDC and includes a 2 m pre-wired cable for direct electrical connection. Light-ON or Dark-ON operation can be selected according to the required machine logic. Its cylindrical radial M18 body measures approximately 57 mm in length and uses a nickel-plated brass housing. Within the E3RB Series, the E3RB-DP11 2M provides the short-range pre-wired PNP option. Related short-range diffuse sensors are available across Omron Sensing Products.

The Omron E3RB-DP11 2M Photoelectric Sensor uses diffuse-reflective sensing in a cylindrical radial format for direct object sensing across a short distance of up to 100 mm. Its red LED sends light toward the target, while returned light supplies the sensing information used to change the PNP output state. The sensor operates from 10 to 30 VDC and includes a 2 m pre-wired cable for fixed electrical connection. Current consumption is specified at 25 mA maximum. Light-ON or Dark-ON operation can be selected according to the required machine logic, while response time is listed at 0.5 ms. The M18 cylindrical body measures approximately 57 mm in length and uses nickel-plated brass, providing a compact threaded metal mounting arrangement.
For an Omron PNP diffuse reflective photoelectric sensor requiring short-range sensing and a pre-wired connection, the relevant model is the E3RB-DP11. Its 100 mm sensing distance is suited to applications where the target passes relatively close to the sensor face. The radial optical orientation supports side-facing mounting from the M18 housing. IP67 and IP69K ratings are listed, supporting operation where the sensor may be exposed to dust or water. The specification also matches searches for an Omron 100 mm PNP sensor and Omron pre wired M18 sensor. For an E3RB PNP model with a longer 300 mm sensing distance and M12 connector, see E3RB-DP22.
