Omron E3T-FT12 2M Photoelectric Sensor
Omron E3T-FT12 2M is an ultrathin through-beam photoelectric sensor designed for object sensing across a maximum distance of 500 mm. Its red LED creates the optical path between the emitter and receiver, while the NPN output transfers the switching state to compatible machine-control circuitry. 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 2 m pre-wired cable for direct electrical connection. Its slim rectangular format supports use in compact equipment. Within the E3T Series, the E3T-FT12 2M provides the Dark-ON NPN configuration. Related NPN through-beam sensors can be explored across Omron Sensor Products.

The Omron E3T-FT12 2M Photoelectric Sensor uses through-beam sensing across a maximum distance of 500 mm in a compact rectangular format. The sensing set uses the E3T-FT12-L emitter and E3T-FT12-D receiver. Its red LED establishes the optical beam between both sides, while the NPN output communicates the switching state from the receiver to compatible control circuitry. Dark-ON operation defines the specified output behavior. The sensor operates from 12 to 24 VDC, with total current consumption of 30 mA max., consisting of 10 mA max. for the emitter and 20 mA max. for the receiver. Operate or reset time is specified at 1 ms max., while the 2 m pre-wired cable supports direct electrical connection.
For an Omron Dark ON through beam photoelectric sensor requiring NPN output and 500 mm sensing, the relevant model is the E3T-FT12. The housing uses polybutylene terephthalate, while denatured polyarylate is listed for the optical section. IP67 protection is specified, and approximate weight is 40 g. This specification also fits searches for an Omron 500 mm NPN sensor and Omron compact through beam sensor. The 1 ms response supports object presence, part counting, and position confirmation where rapid switching is required. For the related Light-ON NPN configuration with the same 500 mm sensing distance and 2 m cable, see E3T-FT11 2M.
