Omron E3T-SL11M 5M Ultracompact Photoelectric Sensor
Omron E3T-SL11M 5M is an ultracompact limited-reflective photoelectric sensor designed for object sensing from 5 to 15 mm. A red LED provides the optical source, while the built-in amplifier processes light returned from the target. Its NPN output communicates the switching state to compatible PLC inputs and machine-control circuits, and Light-ON operation defines the specified output logic. The sensor operates from 12 to 24 VDC, consumes up to 20 mA, and includes a 5 m pre-wired cable for extended wiring. The square body supports close-range sensing in restricted mounting areas. Within the E3T Series, the E3T-SL11M 5M provides the long-cable NPN option. Related compact reflective sensors are available across Omron Automation Products.

The Omron E3T-SL11M 5M Photoelectric Sensor uses limited-reflective sensing across a short 5 to 15 mm range in an ultracompact square body. A red LED supplies the optical light, while the built-in amplifier processes the returned signal from the target. Its NPN output transfers the switching state to compatible PLC inputs and machine-control circuitry, while Light-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 1 ms max. A 5 m pre-wired cable provides additional wiring length, while the ultrathin format supports installation in restricted machine areas.
For an Omron compact limited reflective sensor requiring NPN output and a longer cable, the corresponding model is the E3T-SL11M 5M. Polybutylene terephthalate is listed for the housing, while denatured polyarylate is specified for the optical section. IP67 protection is stated, and approximate weight is 20 g. Its configuration also suits searches for an Omron 15 mm NPN sensor and Omron 5 m cable reflective sensor. The 1 ms response supports close-range part presence, position confirmation, and small-component sensing in compact equipment. For the shorter-cable version with the same sensing range and Light-ON operation, see E3T-SL11M 2M.
