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.","metaTitle":"Omron E3TST112M Photoelectric Sensor, NPN, 1m, 7mm Wide, IP6","metaDescription":"Omron E3TST112M photoelectric proximity sensor, NPN output, 1 m sensing, 12-24 VDC, 50 mA load, 1 ms response, IP67, pre-wired, Light-ON.
