For systems equipped with the GA240.A12C102 model, we offer a precise parallel absolute encoder 1:1 replacement solution engineered for direct interchangeability. The replacement encoder replicates the original device in electrical characteristics, parallel output logic, mechanical dimensions, and functional interfaces, enabling straightforward installation without mechanical modification or software adjustment.
From a technical perspective, GA240.A12C102 is a singleturn optical parallel encoder providing 13-bit absolute position information via 13 parallel outputs. It delivers stable and repeatable code transmission with high absolute accuracy, ensuring reliable position data immediately after power-up. Support for Gray or binary coding, configurable rotation direction by connection, and integrated control inputs (ENABLE, STORE, ZERO, UP/DOWN) allow seamless integration into existing control systems. Short-circuit-proof push-pull outputs and built-in self-diagnostic functions, including continuous code continuity checks, enhance operational safety and data integrity.


Mechanically, the encoder is built in a compact 58 mm aluminum housing, with optional shaft sealing to achieve higher protection levels. It is designed to withstand vibration, shock, high humidity, and extended operating temperatures typical of industrial environments. With verified functional equivalence and mechanical compatibility, this 1:1 parallel encoder replacement provides a reliable and long-term alternative for the GA240.A12C102 model.
