For applications using the GA241.B125102 model, we provide a reliable parallel absolute encoder customized replacement solution. The replacement encoder is engineered to match the original unit in electrical interface, parallel output configuration, resolution, and functional performance, allowing direct installation without modifications to PLC programs, wiring, or control logic. This ensures smooth integration and stable operation in industrial automation and positioning systems.
Technically, GA241.B125102 is a singleturn optical parallel absolute encoder with 13-bit resolution (8192 steps per revolution). Position data is transmitted through 13 parallel outputs, delivering immediate and deterministic feedback after power-up. The encoder supports both Gray and binary coding, with rotation direction (CW/CCW) selectable via wiring configuration. Integrated control inputs including ENABLE, STORE, ZERO, and UP/DOWN provide controlled output activation and flexible system-level position management. Push-pull, short-circuit-proof outputs, along with internal code continuity monitoring and self-diagnostic features, ensure reliable and safe operation in industrial environments.


Mechanically, the replacement encoder is built in a Ø58 mm aluminum housing, with optional shaft sealing for IP65 protection. It is designed for specified mechanical and electrical operating speeds, low starting torque, and defined axial and radial shaft loads suitable for precision-driven machinery. Compliance with industrial EMC standards, resistance to vibration and shock, and tolerance to humidity and wide temperature ranges make this customized replacement solution suitable for material handling systems, automation equipment, and industrial machinery requiring dependable absolute position feedback.
