Omron E3T-ST11 Slotted Type Photoelectric Sensor

Omron E3T-ST11 Slotted Type Photoelectric Sensor is a slot-type optical sensor from Omron designed for non-contact detection in automation applications. The ST11 designation identifies its slotted geometry, which allows sensing targets that pass through a narrow opening without touching them. As part of the E3T family, the E3T-ST11 provides a practical solution for inline sensing tasks that require a through-slot arrangement, enabling reliable detection in compact installations. The slot-type design supports straightforward integration into sensor circuits where space constraints or wiring simplicity matter, and it detects presence or absence of a target by monitoring changes in the optical path when the slot is occupied.
