Omron E3T-FT22 5M Ultracompact Photoelectric Sensor
Omron E3T-FT22 5M is an ultrathin through-beam photoelectric sensor designed for object sensing across a 300 mm distance. A red LED establishes the optical path between the emitter and receiver, while the NPN output supplies the switching state to compatible PLC inputs and control circuits. Dark-ON operation defines the specified output logic, and response time is 1 ms max. The sensor operates from 12 to 24 VDC and includes a 5 m pre-wired cable for longer wiring runs. Within the E3T Series, the E3T-FT22 5M provides the long-cable NPN option. Related 300 mm through-beam sensors are available across Omron Sensors.

The Omron E3T-FT22 5M Photoelectric Sensor uses through-beam sensing across a 300 mm distance in an ultrathin rectangular format. The sensing set uses the E3T-FT22-L emitter and E3T-FT22-D receiver. A red LED establishes the optical path, while the NPN open-collector output transfers the switching state from the receiver to compatible control equipment. Dark-ON operation is specified. The sensor operates from 12 to 24 VDC and consumes 30 mA max. in total, with 10 mA max. for the emitter and 20 mA max. for the receiver. Operate or reset time is 1 ms max., and the 5 m pre-wired cable provides extended wiring length.
For an Omron NPN through beam photoelectric sensor requiring 300 mm sensing and Dark-ON logic, the relevant model is the E3T-FT22 5M. Polybutylene terephthalate is listed for the housing and denatured polyarylate for the optical section. IP67 protection is specified, with an approximate weight of 40 g. This specification also suits searches for an Omron 300 mm through beam sensor and Omron 5 m cable NPN sensor. Its 1 ms switching time supports part presence, counting, and position confirmation across compact machine openings. For the related Light-ON model using the same sensing distance and output type, see E3T-FT21 2M.
