For applications using the GA240.A125102 model, we offer a robust 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 behavior, allowing direct installation without modifications to PLC programs, I/O addressing, or control logic. This ensures reliable and predictable operation in industrial automation systems.
Technically, GA240.A125102 is a singleturn parallel absolute encoder with 13-bit resolution (8192 steps per revolution) utilizing optical sensing technology. Absolute position data is delivered through 13 parallel output channels, providing immediate and unambiguous position feedback after power-up. The encoder supports Gray or binary code, with rotation direction (CW/CCW) configurable via wiring. Integrated control inputs, including ENABLE, STORE, ZERO, and UP/DOWN, allow flexible output management and system-level position control. Push-pull, short-circuit-proof outputs and internal code continuity monitoring ensure reliable signal transmission and operational safety in demanding environments.


Mechanically, the replacement encoder is built in a Ø58 mm aluminum housing, with optional shaft sealing providing protection up to IP65. It supports defined mechanical and electrical operating speeds, low starting torque, and specific axial and radial shaft load limits suitable for precision machinery. Compliance with industrial EMC standards, vibration and shock resistance, humidity tolerance, and extended temperature capability make this customized replacement solution suitable for material handling systems, positioning equipment, and industrial machinery requiring dependable absolute position feedback.
