Omron E3T-CT12 2M Photoelectric Sensor
Omron E3T-CT12 2M is an NPN cylindrical through-beam photoelectric sensor designed for object sensing across a distance of up to 1 m. A red LED establishes the optical path between separate emitter and receiver units, allowing the NPN output to change state when a target interrupts the beam. The sensor operates from 12 to 24 VDC and includes 2 m pre-wired cables for electrical connection. Dark-ON operation is specified, while total current consumption is 30 mA maximum, divided between the emitter and receiver at 15 mA each. Response time is specified at 0.5 ms. Within the E3T Series, the E3T-CT12 2M provides the cylindrical NPN through-beam configuration. Explore 1 m through-beam sensors across Omron Sensing Range.

The Omron E3T-CT12 2M Photoelectric Sensor uses through-beam sensing in a cylindrical housing across a maximum distance of 1 m. A red LED establishes the optical path between separate emitter and receiver units, while the NPN output changes state when an object interrupts the beam. The sensor operates from 12 to 24 VDC and includes 2 m pre-wired cables for electrical integration. Total current consumption is specified at 30 mA maximum, with 15 mA maximum for the emitter and 15 mA maximum for the receiver. Dark-ON operation determines the switching response, while operate or reset time is specified at 0.5 ms maximum. SUS303 is specified for the cylindrical housing, with polysulfone also listed among the materials.
For an Omron NPN through beam photoelectric sensor requiring a compact cylindrical format and 1 m sensing distance, the corresponding model is the E3T-CT12. Its separate emitter and receiver arrangement establishes a dedicated optical path for object presence and passage sensing in limited mounting spaces. The model is specified with IP65 protection and uses fixed pre-wired connections rather than detachable connectors. The specification also suits searches for an Omron 1 m emitter receiver sensor and Omron cylindrical through beam sensor. Its 0.5 ms response supports fast changes in object position across the optical path. For an E3T cylindrical diffuse-reflective model with NPN output and a shorter 3 to 50 mm sensing range, see E3T-CD11 2M.
