Omron E3T-ST14 2M Photoelectric Sensor
Omron E3T-ST14 2M is an ultracompact through-beam photoelectric sensor designed for 1 m object sensing with PNP output and Dark-ON operation. A red LED forms the optical path between separate transmitting and receiving units, and the output changes according to the stated switching logic when the beam condition changes. The sensor operates from 12 to 24 VDC, responds within 1 ms, and includes a 2 m pre-wired cable. Combined current consumption is specified at 30 mA maximum, divided between the emitter and receiver. Its square format supports compact mounting arrangements. Within the E3T Series, the E3T-ST14 2M provides this PNP Dark-ON option. Related compact PNP through-beam sensors are available across Omron Automation Products.

The Omron E3T-ST14 2M 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 PNP output operates in Dark-ON mode for compatible machine-control circuitry. The sensor operates from 12 to 24 VDC and provides a 1 ms response time. Combined current consumption is specified at 30 mA maximum, with 10 mA for the emitter and 20 mA for the receiver. A 2 m pre-wired cable provides the electrical connection. Its square ultracompact format supports installation in restricted spaces, while IP67 protection and the listed PBT and denatured polyarylate housing materials support use in industrial equipment.
For an Omron PNP through beam photoelectric sensor requiring 1 m sensing and Dark-ON operation, the corresponding model is the E3T-ST14. The stated 12 to 24 VDC supply range supports standard DC control circuits, while the 1 ms response is suited to quick beam-state changes. Approximate weight is listed at 40 g. This configuration also fits searches for an Omron 1 m Dark ON sensor and Omron compact PNP sensor. The fixed cable supports direct wiring without a separate connector at the sensor body. For a related PNP Light-ON model with a 2 m cable, see E3T-ST13 2M.
