For systems equipped with the GA240.A126102 model, we provide a precise parallel absolute encoder 1:1 replacement solution designed for direct interchangeability. The replacement encoder mirrors the original device in electrical characteristics, output structure, mechanical dimensions, and functional interfaces, enabling straightforward installation without modifications to hardware or software.
Technically, GA240.A126102 is a singleturn optical parallel encoder delivering 13-bit absolute position data via 13 parallel outputs. It provides high accuracy and stable code output, ensuring immediate position information after power-on. The encoder supports Gray or binary coding, rotation direction configurable by wiring, and integrated control inputs (ENABLE, STORE, ZERO, UP/DOWN) for flexible system-level position management. Push-pull, short-circuit-proof outputs combined with internal self-diagnostic functions, including continuous code continuity verification, ensure consistent and reliable operation in industrial environments.


Mechanically, the encoder features a Ø58 mm aluminum housing, with optional shaft sealing for environmental protection. Designed to withstand vibration, shock, humidity, and extended operating temperatures, it is suitable for continuous-duty operation in demanding industrial applications. Verified functional equivalence and mechanical compatibility make this 1:1 parallel encoder replacement a dependable long-term alternative for the GA240.A126102 model.
