Product details

The Omron E3TST112M is a 7 mm wide photoelectric proximity sensor from the E3T family, with a red LED emitter and NPN output. It switches loads up to 50 mA at 12–24 VDC, responds in 1 ms, and carries a 1 m sensing distance. The 7 mm × 9.5 mm × 18.5 mm body and pre-wired cable simplify installation in compact machine frames. IP67 covers washdown zones. Light-ON logic means the output turns on when the beam detects the target – confirm your PLC expects a sinking (NPN) input, as this unit is NPN, not PNP.

Width 7 mm, height 9.5 mm, length 18.5 mm. Pre-wired cable simplifies installation.

Frequently asked questions

What are the key dimensions?

Width 7 mm, height 9.5 mm, length 18.5 mm.

Does E3TST112M work in a panel originally wired for E3T-ST14?

Not without modification. The output polarity (NPN vs PNP) and switching logic (Light-ON vs Dark-ON) differ. Confirm the PLC input module and wiring before substituting.
