For systems equipped with the GA240.A10C102 model, we offer a precise parallel absolute encoder 1:1 replacement solution. The replacement encoder is engineered to replicate the original model’s electrical characteristics, parallel output structure, mechanical dimensions, and functional interfaces, allowing straightforward installation without modifications to hardware design, software configuration, or commissioning procedures.
From a technical perspective, GA240.A10C102 is a singleturn optical parallel encoder providing 13-bit absolute position data via 13 parallel outputs. The encoder delivers high absolute accuracy of ±0.025° and supports Gray or binary coding, ensuring compatibility with a wide range of industrial controllers. Direction logic is configurable through connection wiring, while control inputs including ENABLE, STORE, ZERO, and UP/DOWN support advanced system coordination and controlled output release. Short-circuit-proof push-pull outputs, combined with integrated self-diagnosis and permanent code continuity checks, contribute to consistent and fault-tolerant operation in demanding industrial environments.


Mechanically, the encoder is built in a Ø58 mm aluminum housing with optional shaft sealing for enhanced environmental protection. It is designed to withstand vibration, shock, high humidity, and extended operating temperatures, making it suitable for continuous-duty industrial applications. Multiple electrical connection options, including connector or cable versions, support flexible installation. With full compliance to industrial EMC standards and verified functional equivalence, this 1:1 parallel encoder replacement provides a dependable, long-term alternative for the GA240.A10C102 model.
