For systems equipped with the GA241.B12C102 model, we offer a precise parallel absolute encoder 1:1 replacement solution for direct interchangeability. The replacement encoder replicates the original unit’s electrical characteristics, parallel output structure, mechanical dimensions, and functional interfaces, allowing installation without hardware or software modifications.
From a technical perspective, GA241.B12C102 is a singleturn optical parallel encoder providing 13-bit absolute position information via 13 parallel outputs. The encoder delivers stable and repeatable code output with high accuracy, ensuring reliable position data immediately after power-on. It supports Gray or binary coding, configurable rotation direction via wiring, and integrated control inputs (ENABLE, STORE, ZERO, UP/DOWN) for controlled system-level operation. Push-pull, short-circuit-proof outputs, combined with self-diagnostic functions and continuous code monitoring, ensure safe and reliable operation in industrial environments.
Mechanically, the encoder is housed in a Ø58 mm aluminum casing, with optional shaft sealing for environmental protection. It is designed to operate reliably under vibration, shock, high humidity, and extended temperature conditions. Verified functional equivalence and mechanical compatibility make this 1:1 parallel encoder replacement a dependable long-term alternative for the GA241.B12C102 model.
