We provide a precision-engineered replacement for the DAF66-12B04, fully matching the 4-20mA absolute output and mechanical dimensions of the original unit. This 1:1 custom alternative ensures direct drop-in installation without any modifications. With a production lead time of 15 working days, it offers a fast and reliable solution for clients facing procurement difficulties or requiring replacements for existing industrial applications.
Technically, this replacement encoder delivers stable current-loop feedback over long cable runs and in electrically noisy environments. Its precise absolute feedback ensures consistent operation, making it ideal for industrial automation, process control systems, and material handling equipment where signal reliability is crucial.
