Omron E3T-ST13 5M Through-Beam Photoelectric Sensor
Omron E3T-ST13 5M is an ultracompact through-beam photoelectric sensor providing a 1 m sensing distance with PNP output and Light-ON operation. Its red LED creates the optical path between the transmitting and receiving units, allowing object presence to be sensed when the beam condition changes. The sensor operates from 12 to 24 VDC, responds within 1 ms, and uses a 5 m pre-wired cable for extended connection length. Combined current consumption is specified at 30 mA maximum, with 10 mA for the emitter and 20 mA for the receiver. Within the E3T Series, the E3T-ST13 5M provides the long-cable PNP option. Related PNP through-beam sensors can be explored across Omron Automation Sensors.

The Omron E3T-ST13 5M Photoelectric Sensor uses through-beam sensing across a 1 m range with separate transmitting and receiving units. A red LED creates the optical path, while the PNP output operates in Light-ON mode for compatible industrial control inputs. The sensor accepts 12 to 24 VDC and provides a 1 ms response time. Combined current consumption is specified at 30 mA maximum, consisting of 10 mA for the emitter and 20 mA for the receiver. A 5 m pre-wired cable provides additional connection length between the sensing point and control equipment. The square ultracompact housing supports installations with limited mounting space, while the stated enclosure protection is IP67 and the listed housing materials are PBT and denatured polyarylate.
For an Omron PNP through beam sensor requiring 1 m sensing, Light-ON switching, and a longer fixed cable, the relevant model is the E3T-ST13. Its 12 to 24 VDC supply range and 1 ms response support quick switching in compact automation layouts. Approximate weight is listed at 40 g. The configuration also suits searches for an Omron 5 m cable PNP sensor and Omron ultracompact photoelectric sensor. For a related NPN Dark-ON version with the same 5 m cable length, see E3T-ST12M 5M.
