Omron E3T-ST11M 5M Through-Beam Photoelectric Sensor
Omron E3T-ST11M 5M is an ultracompact through-beam photoelectric sensor designed for object sensing across a 1 m span. Its red LED establishes the optical path between the emitter and receiver, while the NPN output transfers the switching state to compatible PLC inputs and machine-control circuits. Light-ON operation is specified, and response time is 1 ms max. The sensor operates from 12 to 24 VDC and includes a 5 m pre-wired cable for extended connection length. Total current consumption is 30 mA max. across both sensing sides. Within the E3T Series, the E3T-ST11M 5M provides the long-cable NPN option. Related compact through-beam sensors are available across the Omron Sensor Range.

The Omron E3T-ST11M 5M Photoelectric Sensor uses through-beam sensing across a 1 m span in an ultracompact square format. Its red LED establishes the optical path between the emitter and receiver, while the NPN output transfers the switching state from the receiving side to compatible PLC inputs and control circuits. Light-ON operation is specified. The sensor operates from 12 to 24 VDC and consumes 30 mA max. in total, with 10 mA max. for the emitter and 20 mA max. for the receiver. Operate or reset time is specified at 1 ms max. A 5 m pre-wired cable provides extended connection length for machine installation.
For an Omron compact through beam photoelectric sensor requiring NPN output and longer wiring, the corresponding model is the E3T-ST11M. Polybutylene terephthalate is specified for the housing and denatured polyarylate for the optical section. IP67 protection is stated, while approximate weight is 40 g. Its specification also matches searches for an Omron long cable 1 m sensor and Omron Light ON through beam sensor. The 1 ms response supports presence sensing, counting, and position confirmation in compact automated equipment reliably. For the shorter-cable version with the same sensing distance and output logic, see E3T-ST11M 2M.
