Product details

Through-beam at 500 mm — what it means on the line

The Omron E3T-FT12 is a through-beam photoelectric sensor with a 500 mm sensing distance, NPN open-collector Dark-ON output, and a red 650 nm LED source. It is designed for discrete part-present detection, counting, and break-beam alignment on conveyors, packaging lines, and automated assembly stations where the emitter and receiver mount opposite each other. The IP67 rating means it handles washdown and dusty environments without an additional enclosure.

Response time and supply — fit for standard industrial I/O

The 1 ms response time suits discrete part-present and counting applications. It is not suited for high-speed registration or sub-millisecond edge capture.

Frequently asked questions

What is the difference between E3T-FT12 and E3T-FT11?

The E3T-FT12 has a Dark-ON output (NPN conducts when beam is blocked), while the E3T-FT11 has a Light-ON output (NPN conducts when beam is clear). Both share the same 500 mm sensing distance, IP67 rating, 1 ms response, and cable connection. Swapping them changes the logic of the downstream PLC input.

Can I use a PNP output sensor instead of the E3T-FT12?

Yes, the E3T-FT13 is the PNP Light-ON counterpart in the same E3T series. It has the same sensing distance, response time, and IP67 rating, but outputs a positive voltage instead of sinking to ground. Verify your PLC input module accepts PNP sourcing before substituting.
