QEH81M-10002 Profibus-DP Encoder 1:1 Replacement

We can provide a customized 1:1 replacement solution for the QEH81M-10002 absolute multiturn encoder. The replacement is designed to match the original unit in Profibus-DP communication, electrical performance, and functional behavior, allowing seamless integration into existing automation systems without modifying PLC programs or fieldbus configurations. This solution is suitable for spare part replacement, system refurbishment, and long-term equipment support.

The encoder supports programmable single-turn resolution up to 4096 steps per revolution and programmable multiturn capability up to 4096 revolutions, offering flexible absolute position feedback for industrial motion control. It operates via a Profibus-DP interface with RS485 output, supporting PNO Profile Class 2 and 12 Mbaud communication speed for reliable data exchange. With a wide 11–27 VDC supply range, the encoder meets typical industrial power requirements and ensures stable operation in control cabinets and field installations.

As the original technical documentation for this model cannot be fully verified, customers are required to confirm the shaft bore diameter and mechanical interface details before ordering, to ensure correct mechanical compatibility.
