Omron E3T-CD13 2M Photoelectric Sensor
Omron E3T-CD13 2M is a PNP cylindrical diffuse-reflective photoelectric sensor for compact object sensing across a range of 3 to 50 mm. Its 870 nm infrared LED sends light toward the target, while returned light controls the PNP open-collector output. The sensor operates from 12 to 24 VDC and includes a 2 m pre-wired cable for electrical integration. Light-ON operation is specified, and manual adjustment supports setup for the intended target condition. Current consumption is 20 mA maximum, load current is rated up to 80 mA, and response time is specified at 0.5 ms. Within the E3T Series, the E3T-CD13 2M provides the compact PNP version.

The Omron E3T-CD13 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 PNP open-collector output supplies the switching state to compatible machine-control circuitry. The sensor operates from 12 to 24 VDC and includes a 2 m pre-wired cable for electrical connection. Current consumption is specified at 20 mA maximum, while load current reaches 80 mA maximum with a load supply voltage up to 30 VDC. Light-ON operation is specified, and manual adjustment supports the required sensing condition. Operate or reset time is specified at 0.5 ms maximum.
For an Omron compact PNP diffuse reflective sensor requiring 3 to 50 mm sensing and a pre-wired connection, the relevant model is the E3T-CD13. 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 listed. SUS303, epoxy, and polysulfone are among the specified materials. Its configuration also matches searches for an Omron cylindrical PNP sensor and Omron compact infrared sensor. For the NPN E3T model using the same 3 to 50 mm sensing specification, see E3T-CD11 2M.
