The Telco PA 11 family consists of 1‑channel photoelectric amplifiers designed to condition and process signals from remote photoelectric sensors such as LT and LR series sensors in thru beam, reflective, or polarized retro‑reflective configurations. These amplifiers provide stable and adjustable detection performance by offering sensitivity adjustment, selectable output functions, and indicator feedback for power and sensor status. They are commonly used in industrial automation systems for object detection, position sensing, counting, and presence control across conveyor lines and packaging equipment.
PA 11 models differ in supply voltage, output type, and connector style to suit various system requirements. Amplifiers in this series mount on an 11‑pole DIN socket and include manual potentiometers for sensitivity, light‑on/dark‑on mode selection, and long/short range selection where applicable. Clear LED indicators show power and output states, making alignment and setup fast during installation or maintenance. Their flexible output configurations support relay or transistor switching depending on the specific model chosen.
