Retroreflective sensing out to 3 m on a 75 mm opaque target, minimum blind zone 100 mm from the lens. NPN output, selectable light-on or dark-on via the indicator button. Response time 0.5 ms, load current up to 100 mA at 10-30V DC. ## Installation Notes Prewired 2 m cable with bare ends. IP69K rating holds with the M18 nut torqued to spec; a separate mounting bracket is needed for right-angle orientation. Mirror Surface Rejection (MSR) handles glossy or metallic targets. Set the mode before panel install.","metaTitle":"Omron E3RA-RN112M M18 Retroreflective Sensor, 3m, NPN, IP69K","metaDescription":"Omron E3RA-RN112M photoelectric sensor: M18 retroreflective, 3m range, NPN output, 10-30V DC, 2m cable.
