Omron E3T-SL23 5M Ultracompact Photoelectric Sensor
Omron E3T-SL23 5M is an ultracompact limited-reflective photoelectric sensor designed for short-range object sensing from 5 to 30 mm. Its red LED directs light toward the target, while the built-in amplifier processes the returned optical signal. The PNP output transfers the switching state to compatible industrial control circuits, and Light-ON operation defines the specified behavior. The sensor operates from 12 to 24 VDC, consumes up to 20 mA, and includes a 5 m pre-wired cable for extended machine wiring. Response time is specified at 1 ms max. Within the E3T Series, the E3T-SL23 5M provides the long-cable PNP option. Related PNP reflective sensors can be explored across Omron Sensing Products.

The Omron E3T-SL23 5M Photoelectric Sensor uses limited-reflective sensing across a short 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. The PNP output transfers the switching state to compatible PLC inputs and machine-control circuitry, and Light-ON operation defines the specified behavior. 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 between the sensing point and control equipment.
For an Omron PNP reflective photoelectric sensor requiring Light-ON operation and extended wiring, the corresponding model is the E3T-SL23. 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 suits searches for an Omron 30 mm PNP sensor and Omron 5 m cable reflective sensor. The 1 ms response supports part presence and close-range position confirmation in compact automated equipment. For the related Dark-ON PNP version using the same 5 m cable and sensing range, see E3T-SL24 5M.
