Our replacement program covers the PAM90H28-BF6XXR-4096/8192 model, manufactured through non-standard production with a lead time of 10–15 working days. The new encoder is a 1:1 match to the original, keeping every critical element—mounting flange, hollow shaft configuration, and Profibus communication parameters—fully aligned to guarantee direct interchangeability and ease of installation.
This encoder version is frequently utilized in hoisting equipment, port cranes, and heavy conveyors. Its robust 90 mm construction ensures durability in harsh working environments, while the Profibus interface delivers reliable real-time data transmission.
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.
