Omron E3Z-T61A 0.5M Photoelectric Sensor
The Omron E3Z-T61A 0.5M Photoelectric Sensor provides through-beam object detection across a 15 m sensing distance using a 660 nm red LED light source. The optical beam travels between the transmitting and receiving sides, allowing a target to be detected when it blocks the sensing path. Its NPN output transfers the resulting detection state to compatible industrial control inputs, while selectable Light-ON and Dark-ON operation allows the switching logic to match the required condition. The sensor operates from a 12 to 24 VDC supply and includes a 0.5 m pre-wired cable. The visible red light source distinguishes this supplied A variant from E3Z-T61 models specified with an infrared LED. The E3Z-T61A 0.5M sits within the E3Z Series and the long-range through-beam sensing range from Omron detection technology.

The Omron E3Z-T61A 0.5M Photoelectric Sensor uses through-beam sensing across a specified distance of 15 m. A 660 nm red LED establishes the optical path between the transmitting and receiving sides, and the sensing state changes when a target interrupts the beam. The NPN output communicates the switching condition to compatible PLC and machine-control circuitry. The sensor operates from 12 to 24 VDC and includes a 0.5 m pre-wired cable for short fixed connection. Light-ON or Dark-ON operation can be selected according to the required control sequence, while response time is specified at 1 ms maximum. PBT is listed for the case and denatured polyarylate for the optical material. The visible red light source distinguishes this supplied configuration from E3Z-T61 listings specified with an infrared LED.
For an Omron through-beam photoelectric sensor requiring NPN output, visible red light, and short pre-wired connection, the relevant model is the E3Z-T61A. The supplied information does not state separate emitter and receiver model numbers for this 0.5 m listing, so none are added. Its 15 m stated range supports sensing across wider machine openings where a separate transmitting and receiving arrangement is suitable. The 12 to 24 VDC supply and selectable switching logic support connection with compatible industrial control inputs. For a related E3Z-T61A version with explicitly listed emitter and receiver units and 2 m pre-wired cables, see E3Z-T61A 2M.
