We provide a full replacement solution for the EAM90L28-BF6XXR-4096/8192DP model, manufactured on a non-standard customized basis with a delivery cycle of 10–15 working days. The alternative encoder is designed on a strict 1:1 parameter basis, ensuring the same mounting dimensions, shaft configuration, and electrical performance as the original unit, which allows users to overcome procurement difficulties without modifying their systems.
This encoder is widely applied in heavy machinery, cranes, and steel processing equipment where stable Profibus communication and high resolution feedback are essential. Its 90 mm housing and hollow shaft design give it excellent adaptability in demanding installations.
Replacement solution product image.
Profibus-DP interface absolute multiturn encoder EAM90L series delivers outstanding performance in withstanding mechanical damages and higher axial and radial loads. Through-hole installations and various types of shafts diameters could meet the different requirements of customers. It complies with Profibus protocol and has a maximum resolution of 8192 and revolution of 4096. The resolution and revolution can be programmed on request. Its high speed communication and anti-interference performance ensure a steady operation.
