Omron E3T-SL14M 5M Ultracompact Photoelectric Sensor
Omron E3T-SL14M 5M is an ultracompact limited-reflective photoelectric sensor designed for object sensing from 5 to 30 mm. A red LED directs light toward the target, while the built-in amplifier processes the returned optical signal. Its NPN output supplies the switching state to compatible PLC inputs and control circuits, and Light-ON operation defines the specified 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 compact mounting positions. Within the E3T Series, the E3T-SL14M 5M provides the long-cable NPN option. Related compact reflective sensors can be explored across Omron Industrial Products.

The Omron E3T-SL14M 5M Photoelectric Sensor uses limited-reflective sensing across a 5 to 30 mm range in an ultracompact square body. A red LED directs light toward the target, while the built-in amplifier processes the returned optical signal. Its NPN output transfers the switching state to compatible PLC inputs and machine-control circuitry, and 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 specified at 1 ms max. A 5 m pre-wired cable provides additional wiring length, while the thin format supports close-range sensing in compact machine areas.
For an Omron compact limited reflective sensor requiring NPN output and 5 to 30 mm sensing, the relevant model is the E3T-SL14M 5M. Polybutylene terephthalate is listed for the housing and denatured polyarylate for the optical section. IP67 protection is specified, while approximate weight is 20 g. Its configuration also matches searches for an Omron Light ON reflective sensor and Omron long cable NPN sensor. The 1 ms response supports short-range part presence and position confirmation in compact automated equipment. For a related NPN model with the same sensing range and a shorter cable, see E3T-SL21 2M.
