The 8.9080.4C31.3001 encoder can be supported through a custom compatible solution for maintenance, retrofit, replacement, and upgrade applications where a 25 mm hollow shaft flange-mounted encoder with cable gland connection must be maintained. Typical production lead time: 15 working days. This version places equal importance on shaft-size continuity, flange-based positioning, and terminal-box field wiring practice.
Technical Overview of the 8.9080.4C31.3001 Encoder
This model is part of the multiturn 9080 absolute encoder platform with PROFIBUS DP interface, RS485 physical layer, binary code, and scalable resolution architecture up to 25 bits overall. It supports programmable direction of rotation, preset value, scaling factor, and diagnostics mode and operates from 10 ... 30 V DC in an IP65 housing.
Its coded structure identifies a mounting flange, 25 mm H7 through hollow shaft, and removable bus terminal cover with cable gland M16. This makes it a large-bore, flange-mounted, terminal-box style variant suited to installations where the shaft interface and cable entry arrangement are already fixed by machine design.
Industrial Integration Considerations
A 25 mm flange-mounted hollow shaft encoder should be reviewed carefully for shaft fit, flange contact condition, and housing alignment before replacement. Large-bore flange versions are generally selected for specific mechanical reasons, so preserving that configuration is essential for practical compatibility.
The cable gland terminal-box layout also affects service work. Where existing plant wiring uses direct cable entry and enclosed termination, changing to a connectorized variant can create avoidable rework. Matching the original connection concept is therefore a meaningful part of engineering continuity.
Custom Compatible Encoder Solution
For 8.9080.4C31.3001, a custom compatible encoder solution should preserve the 25 mm through hollow shaft, mounting flange, and cable gland terminal cover while matching PROFIBUS DP class 2 communication and scalable multiturn absolute behavior. That combination helps minimize installation changes and supports smoother recommissioning.
During engineering review, the original address setting, preset handling, and scaling logic should also be checked so the final configuration remains aligned with the existing field application.

Lead Time and Custom Development
Typical production lead time: 15 working days.
Custom development should verify bore tolerance, flange reference dimensions, cable entry requirements, and bus parameter settings. On this model, the combination of large bore and flange mounting defines the core compatibility path.
