Omron E3T-FT12 Through Beam Photoelectric Sensor

The Omron E3T-FT12 Through Beam Photoelectric Sensor is a through-beam photoelectric switch designed for non-contact detection of objects by interrupting a light beam between an emitter and a receiver. With an operating range of 12–24 VDC and a 2 m sensing distance, it provides a compact, electrical-compatible solution for fast, reliable part detection in automation setups. The E3T-FT12 model designation identifies a member of Omron's E3T photoelectric family, known for simple installation and robust performance in basic presence/absence sensing tasks. In a typical through-beam configuration, the emitter and receiver are mounted on opposite sides of the target path, allowing precise detection even at moderate speeds or with challenging backgrounds depending on installation. This sensor type is commonly used wherever contactless sensing is preferred to mechanical switches, reducing wear and particulate contamination in conveyors, packaging lines, and assembly processes.
