Omron E3T-FD11 2M Photoelectric Sensor
Omron E3T-FD11 2M is an ultrathin diffuse-reflective photoelectric sensor designed for short-range object sensing from 5 to 30 mm. A red LED directs light toward the target, while the NPN output provides the resulting switching signal to compatible PLC inputs and machine-control circuits. Light-ON operation is specified, and the 1 ms max. response supports applications where quick switching is required. The sensor operates from 12 to 24 VDC, consumes up to 20 mA, and includes a 2 m pre-wired cable. Its rectangular body supports mounting in compact equipment. Within the E3T Series, the E3T-FD11 2M provides the Light-ON NPN configuration. Related short-range diffuse sensors can be reviewed across Omron Automation Sensors.

The Omron E3T-FD11 2M Photoelectric Sensor uses diffuse-reflective sensing across a short range of 5 to 30 mm. A red LED directs light toward the target, and returned light is processed by the built-in amplifier to establish the switching state. The NPN output connects with compatible PLC inputs and control circuits, while Light-ON operation provides the specified switching logic. Operating voltage is 12 to 24 VDC, with current consumption specified at 20 mA max. The sensor provides an operate or reset time of 1 ms max. and includes a 2 m pre-wired cable for connection. Its ultrathin rectangular format supports installation in restricted mounting areas where a conventional sensor body may require more space.
For an Omron NPN diffuse reflective photoelectric sensor requiring short-range 5 to 30 mm sensing, the applicable model is the E3T-FD11. The housing uses polybutylene terephthalate, while denatured polyarylate is listed for the optical section. IP67 protection is specified, and the approximate weight is 20 g. Its configuration also suits searches for an Omron ultrathin photoelectric sensor and Omron 30 mm diffuse sensor. The 1 ms response supports small-part presence sensing, component positioning, and compact machine sequences where short sensing distance is required. For a related E3T model using the same short sensing range with the alternative operating logic, see E3T-FD12 2M.
