Omron E3T-CT14 2M Ultracompact Photoelectric Sensor
Omron E3T-CT14 2M is an ultracompact cylindrical through-beam photoelectric sensor designed for a sensing distance of 1 m. Its red LED establishes the optical path between the emitter and receiver, while the PNP output sends the switching state to compatible PLC inputs and control circuits. Dark-ON operation is specified, with a response time of 0.5 ms max. The sensor operates from 12 to 24 VDC and uses a 2 m pre-wired cable. Its stainless-steel cylindrical body supports installation where mounting space is limited. Within the E3T Series, the E3T-CT14 2M provides the 1 m PNP option. Related cylindrical through-beam sensors are available across Omron Sensors.

The Omron E3T-CT14 2M Photoelectric Sensor uses a cylindrical through-beam sensing arrangement with a maximum sensing distance of 1 m. The through-beam set consists of the E3T-CT14-L emitter and E3T-CT14-D receiver. A red LED provides the optical source between both sides, while the PNP open-collector output transfers the switching state from the receiver to compatible control circuitry. The sensor operates from 12 to 24 VDC, and current consumption is specified at 15 mA max. for the emitter and 15 mA max. for the receiver. Dark-ON operation is provided, with operate or reset time specified at 0.5 ms max. The 2 m pre-wired cable supports direct connection, while the stainless-steel cylindrical housing provides a compact mounting format.
For an Omron PNP through beam photoelectric sensor requiring 1 m sensing and a small cylindrical body, the corresponding model is the E3T-CT14. The control output supports up to 30 VDC and 80 mA with a residual voltage of 1 V max. The sensor is specified with IP65 protection, while SUS303 is listed for the housing and polysulphone for the optical section. Its specification also suits searches for an Omron 1 m through beam sensor and Omron cylindrical PNP sensor. The 0.5 ms response supports fast object-presence switching in compact equipment. For a related cylindrical E3T option using NPN output with the same 1 m sensing distance and Dark-ON logic, see E3T-CT12 2M.
