Omron E3T-ST14M 5M Through-Beam Photoelectric Sensor
Omron E3T-ST14M 5M is an ultracompact through-beam photoelectric sensor combining a 1 m sensing distance with PNP output and Dark-ON operation. Its red LED forms the optical path between the transmitting and receiving units, while the built-in amplifier processes the beam condition before the output signal is transferred to compatible control equipment. The sensor operates from 12 to 24 VDC, responds within 1 ms, and includes a 5 m pre-wired cable for extended installation reach. Combined current consumption is specified at 30 mA maximum. The M-design supports compact mounting requirements. Within the E3T Series, the E3T-ST14M 5M provides this long-cable PNP option.

The Omron E3T-ST14M 5M Photoelectric Sensor uses through-beam sensing across a 1 m distance with separate transmitting and receiving units. A red LED establishes the optical path, while the built-in amplifier processes the beam condition before the PNP output changes state. Dark-ON operation defines the specified output behavior. The sensor operates from 12 to 24 VDC and provides a 1 ms response time. Combined current consumption is 30 mA maximum, consisting of 10 mA for the emitter and 20 mA for the receiver. A 5 m pre-wired cable provides extended connection length. The supplied description identifies an M3-mounting design, while the ultracompact format supports installation where available sensor space is restricted.
For an Omron PNP through beam sensor requiring 1 m sensing, Dark-ON operation, M3 mounting, and a 5 m cable, the relevant model is the E3T-ST14M. The listed enclosure protection is IP67, and PBT plus denatured polyarylate are specified as materials. Approximate weight is 40 g. This configuration also suits searches for an Omron M3 photoelectric sensor and Omron ultrathin PNP sensor. The 12 to 24 VDC supply range supports standard DC control circuits, while the long pre-wired cable offers additional installation reach. For a related Light-ON PNP version with a 5 m cable, see E3T-ST13M 5M.
