Omron E3T-FD12 2M Photoelectric Sensor
Omron E3T-FD12 2M is an ultrathin diffuse-reflective photoelectric sensor designed for a 5 to 30 mm sensing range using a 50 × 50 mm white-paper reference target. Its 650 nm red LED provides the optical source, while the NPN open-collector output supplies the switching signal to compatible control circuitry. Light-ON operation is specified, and operate or reset time is 1 ms max. The sensor operates from 12 to 24 VDC and consumes up to 20 mA. A 2 m pre-wired cable supports electrical connection, while orange operation and green stability indicators provide status information. Within the E3T Series, the E3T-FD12 2M provides the NPN short-range configuration. Related NPN diffuse-reflective sensors are available across the Omron Sensor Range.

The Omron E3T-FD12 2M Photoelectric Sensor uses diffuse-reflective sensing across a specified range of 5 to 30 mm with a 50 × 50 mm white-paper reference target. A 650 nm red LED provides the optical source, while the NPN open-collector output transfers the switching state to compatible control equipment. Light-ON operation is specified, and operate or reset time is 1 ms max. The sensor operates from 12 to 24 VDC with current consumption of 20 mA max. Output load current is specified at 50 mA max., with load power-supply voltage up to 26.4 VDC. A 2 m pre-wired cable provides the electrical connection, while orange operation and green stability indicators provide visual status during setup.
For an Omron NPN diffuse reflective photoelectric sensor requiring 5 to 30 mm sensing and a compact rectangular format, the corresponding model is the E3T-FD12. Operating temperature extends from -25 to 55°C, while storage is specified from -40 to 70°C without icing or condensation. Power-supply and control-output reverse-polarity protection, output short-circuit protection, and mutual-interference prevention are specified. PBT and denatured polyarylate are listed among the materials. Its specification also supports searches for an Omron 650 nm photoelectric sensor and Omron 30 mm NPN sensor. For the related short-range E3T model using Light-ON NPN operation with the same 2 m cable format, see E3T-FD11 2M.
