For installations using the GA240.A105102 model, we offer a well-proven parallel absolute encoder customized replacement solution. The replacement encoder is engineered to align with the original unit in terms of electrical interface, parallel output logic, resolution, and functional behavior, allowing direct installation without changes to PLC programs, I/O configuration, or control logic. This ensures a smooth replacement process and stable operation in existing industrial systems.
From a technical standpoint, GA240.A105102 is a singleturn parallel absolute encoder with a 13-bit resolution (8192 steps per revolution), utilizing optical sensing technology for reliable position detection. Position data is transmitted via 13 parallel output channels, providing immediate and unambiguous absolute position information after power-on, with a typical initialization time of approximately 20 ms. The encoder supports both Gray code and binary code, with rotation direction (CW / CCW) defined by wiring. Integrated control inputs such as 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 contribute to consistent signal quality and operational safety.


Mechanically, the replacement encoder is built in a Ø58 mm aluminum housing, with selectable protection up to IP65 when equipped with a shaft seal. It supports high mechanical speeds, low starting torque, and defined axial and radial shaft loads suitable for precision-driven machinery. Compliance with industrial EMC standards, along with resistance to vibration, shock, temperature variation, and humidity, makes this customized replacement solution suitable for automation equipment, positioning systems, and industrial machinery requiring dependable absolute position feedback.
