We provide a high-precision replacement for the DAF66-12B19, fully reproducing the 4-20mA absolute output and mechanical mounting dimensions of the original unit. Produced as a 1:1 custom solution, it allows direct installation without modifications. With a standard production lead time of 15 working days, this replacement addresses supply constraints and provides a reliable solution for industrial applications requiring continuity and accuracy.
Designed for stable current-loop feedback over long cable runs and in electrically noisy environments, this encoder ensures precise absolute position measurement. It is well-suited for industrial automation, process control, and material handling systems, delivering consistent performance in demanding operational conditions.
