Omron E3T-FL23 2M Photoelectric Sensor
Omron E3T-FL23 2M is an ultrathin BGS reflective photoelectric sensor designed for object sensing across a 1 to 30 mm range. Background suppression helps reduce the influence of surfaces outside the intended target area, while a 650 nm red LED provides the optical sensing source. Its PNP open-collector output supplies the switching state to compatible PLC inputs and control circuitry. Light-ON operation is specified, and operate or reset time is 1 ms max. The sensor operates from 12 to 24 VDC, consumes 20 mA, and includes a 2 m pre-wired cable. Within the E3T Series, the E3T-FL23 2M provides the PNP 30 mm BGS configuration. Related PNP background suppression sensors can be reviewed across Omron Sensing Range.

The Omron E3T-FL23 2M Photoelectric Sensor uses BGS reflective sensing across a 1 to 30 mm range with a 50 × 50 mm white-paper reference target. Its background suppression function helps keep the sensing area focused on the intended target while reducing the influence of surfaces behind it. A 650 nm red LED provides the optical source, and a 0.15 mm diameter non-glossy target can be sensed at a 10 mm distance under the stated condition. The PNP open-collector output transfers the switching state to compatible control circuitry, while Light-ON operation is specified. Operating voltage is 12 to 24 VDC, current consumption is 20 mA max., and operate or reset time is 1 ms max. A 2 m pre-wired cable provides the electrical connection.
For an Omron PNP background suppression photoelectric sensor requiring 1 to 30 mm sensing, the corresponding model is the E3T-FL23. Output load current is specified at 50 mA max., with load power-supply voltage up to 26.4 VDC. Operating temperature extends from -25 to 55°C, while storage reaches -40 to 70°C without icing or condensation. Reverse-polarity protection, output short-circuit protection, and mutual-interference prevention are specified. Its configuration also matches searches for an Omron PNP BGS sensor and Omron 30 mm Light ON sensor. For the related NPN version using the same Light-ON operation and 1 to 30 mm BGS sensing range, see E3T-FL21 2M.
