Rated at 12-24 VDC and with a maximum load current of 50 mA, it includes output reverse polarity protection, output short-circuit protection, and supply reverse polarity protection — built-in safeguards that reduce callbacks on wiring mistakes. The prewired 2 m cable with bare wire ends terminates to the sensor at a right angle, and the red LED indicator gives positive confirmation of the light-ON switching state. ## How it stacks against the siblings Within the E3T diffuse family, the E3T-SL23 (PNP, 30 mm) sits between the E3T-SL13 (PNP, 15 mm) and the E3T-SL21 (NPN, 30 mm). The PNP output and 30 mm range make the SL23 the preferred choice when the controller inputs are sourcing and the detection standoff needs the full 30 mm reach. If your panel is already wired for NPN, the E3T-SL21 drops in with the same mechanical footprint and cable arrangement. If the application only needs 15 mm and you have PNP, the E3T-SL13 is identical in all other specs — same 2 m cable, same 1 ms response, same IP67 — and can serve as a second-source for shorter-range jobs without rewiring.","metaTitle":"Omron E3T-SL23 Photoelectric Sensor, PNP, 30mm Diffuse, IP67","metaDescription":"E3T-SL23 diffuse photoelectric sensor from Omron, PNP output, 5-30mm sensing range, 1ms response, IP67, 2m cable.
