The Omron E3FCTP21OMS is a through-beam photoelectric sensor from the E3FC family, fitted with a red LED and PNP output. It throws a 20 m beam across an open gap, rated for washdown with IP67, IP68, and IP69K protection – meaning it holds up to high-pressure hot water in food or chemical lines. Switching speed is 500 µs, so it catches fast-moving parts on a conveyor. Supply range 10–30 VDC, and the PNP output sinks up to 100 mA – enough to drive a PLC input or small relay directly. The M12 4-pin connector is standard for industrial quick-disconnect. Operating temperature from -25 to 55 °C covers most indoor machine environments.

Frequently asked questions
What is the length of E3FCTP21OMS?
The sensor body length is 48 mm.
What series is E3FCTP21OMS part of?
It belongs to the Omron E3FC series.
Will E3FCTP21OMS drop into a panel specified for E3SDBP21TOMS without rewiring?
No – the two sensors use different sensing principles (through-beam vs retro-reflective) and have different body dimensions. Interchangeability cannot be assumed without verifying mounting and wiring.
