For applications using the GA241.B105102 model, we offer a reliable parallel absolute encoder customized replacement solution. The replacement encoder is engineered to match the original unit in electrical interface, output structure, resolution, and functional performance, enabling direct installation without changes to PLC logic, wiring, or software configuration. This ensures stable operation and minimal commissioning time in industrial automation and machinery systems.
Technically, GA241.B105102 is a singleturn optical parallel absolute encoder with 13-bit resolution (8192 positions per revolution). Absolute position data is delivered via 13 parallel outputs, providing immediate and deterministic feedback after power-on. The encoder supports both Gray and binary coding, with rotation direction (CW/CCW) selectable through wiring. Integrated control inputs including ENABLE, STORE, ZERO, and UP/DOWN allow controlled output release and flexible system-level position handling. Push-pull, short-circuit-proof outputs and continuous code monitoring ensure reliable signal transmission and operational safety.


Mechanically, the replacement encoder is housed in a Ø58 mm aluminum casing, with optional shaft sealing for IP65 protection. It is designed for defined mechanical and electrical operating speeds, low starting torque, and specified axial and radial shaft loads suitable for precision machinery. Compliance with industrial EMC standards, as well as resistance to vibration, shock, humidity, and wide temperature ranges, makes this customized replacement solution suitable for industrial automation, positioning systems, and heavy machinery applications requiring dependable absolute position feedback.
