Omron E3T-FD12 5M Ultracompact Photoelectric Sensor
Omron E3T-FD12 5M is an ultracompact diffuse-reflective photoelectric sensor designed for object sensing across a short range of 5 to 30 mm. A red LED directs light toward the target, while the NPN output supplies the resulting switching signal to compatible industrial control circuitry. Dark-ON operation defines the specified output behavior, and the sensor responds within 1 ms max. It operates from 12 to 24 VDC with current consumption of up to 20 mA. A 5 m pre-wired cable provides additional wiring distance for installation, while the rectangular body supports compact mounting. Within the E3T Series, the E3T-FD12 5M provides the long-cable Dark-ON version. Related Dark-ON diffuse sensors can be compared across Omron Industrial Products.

The Omron E3T-FD12 5M Photoelectric Sensor uses diffuse-reflective sensing across a 5 to 30 mm range in an ultracompact rectangular format. A red LED provides the optical source, and returned light from the target is processed by the built-in amplifier to establish the switching state. Its NPN output communicates with compatible PLC inputs and control circuits, while Dark-ON operation defines the specified output logic. The sensor operates from 12 to 24 VDC and consumes up to 20 mA. Operate or reset time is specified at 1 ms max. A 5 m pre-wired cable provides additional connection length for equipment where the control panel is positioned farther from the sensing point. The enclosure is specified with IP67 protection.
For an Omron Dark ON diffuse photoelectric sensor requiring a 5 m cable and 5 to 30 mm sensing, the relevant model is the E3T-FD12 5M. Polybutylene terephthalate is listed for the housing and denatured polyarylate for the optical section, while approximate weight is 20 g. This model also suits searches for an Omron 5 m cable NPN sensor and Omron short distance photoelectric sensor. Its 1 ms response supports quick switching for small components, position confirmation, and presence sensing in compact equipment. For the corresponding Light-ON version using the same 5 m cable and sensing range, see E3T-FD11 5M.
