Omron E3T-ST13M 5M Through-beam Photoelectric Sensor
Omron E3T-ST13M 5M is an ultracompact through-beam photoelectric sensor with a 1 m sensing distance, PNP output, and Light-ON operation. Its red LED establishes the optical path between the transmitting and receiving units, while the built-in amplifier processes the beam condition before the output changes state. The sensor operates from 12 to 24 VDC and includes a 5 m pre-wired cable for installations requiring additional connection length. Response time is specified at 1 ms, and combined current consumption is 30 mA maximum. Within the E3T Series, the E3T-ST13M 5M provides the long-cable PNP configuration. Similar 1 m photoelectric sensors can be reviewed across Omron Industrial Sensor Products.

The Omron E3T-ST13M 5M Photoelectric Sensor uses through-beam sensing across a 1 m distance in an ultracompact square format. Separate transmitting and receiving units establish the red LED optical path, while the built-in amplifier processes the beam condition before the PNP output changes state. Light-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, with 10 mA for the emitter and 20 mA for the receiver. A 5 m pre-wired cable provides extended wiring length, making this version suitable where the sensing point and control equipment are separated by a greater distance.
For an Omron PNP through beam sensor requiring a 1 m range, Light-ON operation, and a 5 m fixed cable, the relevant model is the E3T-ST13M. The listed enclosure protection is IP67, while PBT and denatured polyarylate are specified as housing materials. Approximate weight is 40 g. Its compact format also suits searches for an Omron ultrathin photoelectric sensor and Omron 5 m cable sensor. The 12 to 24 VDC supply range supports standard DC machine-control circuits. For a related Dark-ON PNP model with the same 5 m cable length, see E3T-ST14M 5M.
