Omron E3T-SL12M 5M Ultracompact Photoelectric Sensor
Omron E3T-SL12M 5M is an ultrathin limited-reflective photoelectric sensor designed for short-range object sensing from 5 to 15 mm. Its red LED supplies the optical source, while the built-in amplifier processes light returned from the target. An NPN output communicates the switching state to compatible industrial control circuits, and Dark-ON operation defines the specified output behavior. The sensor runs from 12 to 24 VDC, consumes up to 20 mA, and includes a 5 m pre-wired cable for longer wiring runs. Within the E3T Series, the E3T-SL12M 5M provides the extended-cable Dark-ON option.

The Omron E3T-SL12M 5M Photoelectric Sensor uses limited-reflective sensing across a 5 to 15 mm range in an ultracompact square format. Its red LED directs light toward the target, while the built-in amplifier processes the returned optical signal. The NPN output communicates the switching state to compatible industrial control circuits, and Dark-ON operation defines the specified output behavior. The sensor operates from 12 to 24 VDC and consumes up to 20 mA. Operate or reset time is 1 ms max. A 5 m pre-wired cable provides longer wiring between the sensing position and control equipment, while the thin body supports restricted mounting locations.
For an Omron limited reflective photoelectric sensor requiring NPN output, Dark-ON logic, and longer wiring, the corresponding model is the E3T-SL12M 5M. Polybutylene terephthalate is specified for the housing and denatured polyarylate for the optical section. IP67 protection is stated, with approximate weight of 20 g. This configuration also suits searches for an Omron 5 m cable reflective sensor and Omron Dark ON NPN sensor. The 1 ms response supports close-range part presence and position confirmation in compact automated equipment and short machine cycles. For the shorter-cable version with the same sensing range and output logic, see E3T-SL12M 2M.
