For systems equipped with the GA241.B126102 model, we provide a precise parallel absolute encoder 1:1 replacement solution designed for direct compatibility. The replacement encoder replicates the original unit’s electrical characteristics, parallel output structure, mechanical dimensions, and functional interfaces, allowing installation without modifications to existing hardware or software systems.
From a technical perspective, GA241.B126102 is a singleturn optical parallel encoder delivering 13-bit absolute position data via 13 parallel outputs. It provides stable, repeatable code output with high absolute accuracy, ensuring immediate availability of position information after power-up. Support for Gray or binary coding, configurable rotation direction via wiring, and integrated control inputs (ENABLE, STORE, ZERO, UP/DOWN) allow controlled system-level operation. Push-pull short-circuit-proof outputs, combined with self-diagnostic features and continuous code continuity monitoring, ensure reliable operation in demanding industrial environments.


Mechanically, the encoder is housed in a Ø58 mm aluminum casing, with optional shaft sealing to achieve environmental protection. It is designed to withstand vibration, shock, humidity, and extended temperature ranges, making it suitable for continuous-duty industrial applications. Verified functional equivalence and mechanical compatibility make this 1:1 parallel encoder replacement a dependable long-term alternative for the GA241.B126102 model.
