Omron E3T-CD11 2M Photoelectric Sensor
Omron E3T-CD11 2M is an NPN cylindrical diffuse-reflective photoelectric sensor designed for compact object sensing from 3 to 50 mm. Its 870 nm infrared LED directs light toward the target, while returned light provides the switching information without requiring a separate reflector. The sensor operates from 12 to 24 VDC and includes a 2 m pre-wired cable for connection. Light-ON operation is specified, while the NPN open-collector output supports load current up to 80 mA. Current consumption is limited to 20 mA, and response time is specified at 0.5 ms. Within the E3T Series, the E3T-CD11 2M provides the compact NPN cylindrical configuration.

The Omron E3T-CD11 2M Photoelectric Sensor uses a small cylindrical diffuse-reflective arrangement for direct object sensing across a range of 3 to 50 mm using a 100 × 100 mm white-paper reference target. Its 870 nm infrared LED provides the optical source, while the NPN open-collector output transfers the switching state to compatible machine-control circuitry. The sensor operates from 12 to 24 VDC and includes a 2 m pre-wired cable. Current consumption is specified at 20 mA maximum, while load current reaches 80 mA maximum with load supply voltage up to 30 VDC. Light-ON operation is specified, while operate or reset time is 0.5 ms maximum. Orange operation and green stability indicators provide visual information during setup.
For an Omron compact NPN diffuse reflective sensor requiring a 3 to 50 mm working range and fixed cable connection, the applicable model is the E3T-CD11. Incandescent-light resistance is specified at 3,000 lx maximum. Operating temperature extends from -25 to 55°C, while storage ranges from -30 to 70°C without icing or condensation. Power-supply reverse polarity and output short-circuit protection are included. SUS303, epoxy, and polysulfone are among the stated materials. Its specification also suits searches for an Omron cylindrical NPN sensor and Omron 50 mm photoelectric sensor. For the PNP E3T version using the same 3 to 50 mm sensing range, see E3T-CD13 2M.
