Omron E3FB-RP12 2M Photoelectric Sensor
Omron E3FB-RP12 2M is a PNP coaxial retro-reflective photoelectric sensor with a 500 mm sensing distance and red LED optical source. Its coaxial arrangement aligns transmitted and returning light along the sensing axis, supporting reflector-based sensing in compact machine layouts. The sensor operates from 10 to 30 VDC and includes a pre-wired 2 m cable for fixed electrical connection. Light-ON or Dark-ON switching can be selected to match the required control sequence, while response time is specified at 0.5 ms. The M18 cylindrical body uses nickel-plated brass. Within the E3FB Series, the E3FB-RP12 2M provides the coaxial PNP option. Compact reflector applications can review coaxial retro-reflective sensors available through Omron Sensor Products.

The Omron E3FB-RP12 2M Photoelectric Sensor features coaxial retro-reflective sensing over a 500 mm distance using a red LED optical source. The coaxial arrangement aligns transmitted and returning light along the sensing axis, allowing the sensor to work with reflector-based targets in compact layouts. Its PNP output communicates the switching state to compatible control circuitry, while the 10 to 30 VDC supply supports standard machine-control systems. A pre-wired 2 m cable provides fixed electrical connection. Current consumption is specified at 25 mA max. Light-ON or Dark-ON operation can be selected according to the control sequence, and response time is 0.5 ms. The M18 cylindrical axial body measures 44 mm and uses nickel-plated brass with IP67 and IP69K protection.
For an Omron coaxial photoelectric sensor requiring PNP output, 500 mm sensing, and pre-wired installation, the corresponding model is the E3FB-RP12. Its coaxial optical format is useful where emitted and returned light need to follow the same sensing axis. The specification also fits searches for an Omron 500 mm retro-reflective sensor and Omron M18 PNP photoelectric sensor. For a related E3FB PNP retro-reflective model providing a longer 0.1 to 4 m range with fixed 2 m wiring, see E3FB-RP11 2M.
