Omron E3T-FL12 2M Ultracompact Photoelectric Sensor
Omron E3T-FL12 2M is an ultrathin BGS reflective photoelectric sensor for short-distance object sensing across a 1 to 15 mm range. Its background suppression function helps limit the sensing zone by reducing the effect of surfaces beyond the intended target position. A red LED provides the optical source, while the NPN output sends the switching state to compatible PLC inputs and control circuits. Dark-ON operation defines the specified output behavior, and response time is 1 ms max. The sensor operates from 12 to 24 VDC, consumes up to 20 mA, and includes a 2 m pre-wired cable. Within the E3T Series, the E3T-FL12 2M provides the Dark-ON BGS option. Related Dark-ON BGS sensors are available across Omron Automation Products.

The Omron E3T-FL12 2M Photoelectric Sensor uses BGS reflective sensing across a defined 1 to 15 mm range in an ultrathin rectangular format. The background suppression function helps reduce the influence of surfaces beyond the required target area. A red LED provides the optical source, while the built-in amplifier processes the returned sensing signal. Its NPN output supplies the switching state to compatible PLC inputs and machine-control circuits, and Dark-ON operation defines the specified logic. The sensor operates from 12 to 24 VDC and consumes up to 20 mA. Operate or reset time is specified at 1 ms max., while a 2 m pre-wired cable provides direct electrical connection. The compact format supports mounting in restricted equipment spaces.
For an Omron Dark ON background suppression sensor requiring NPN output and a 1 to 15 mm sensing range, the relevant model is the E3T-FL12. Polybutylene terephthalate is listed for the housing and denatured polyarylate for the optical section. IP67 protection is specified, and approximate weight is 20 g. This configuration also matches searches for an Omron short range BGS sensor and Omron ultrathin NPN sensor. Its 1 ms switching response supports component presence, edge confirmation, and position sensing in compact machine areas. For the related Light-ON NPN version using the same BGS method, cable length, and 1 to 15 mm sensing range, see E3T-FL11 2M.
