We provide a 1:1 custom replacement for the DAF66-12B17, matching the original 4-20mA absolute output and mechanical alignment. Designed for direct drop-in installation, this solution requires no electrical or mechanical modifications. With a standard production lead time of 15 working days, it offers a practical and cost-effective option for maintaining operation when facing supply issues or model obsolescence.
Developed for industrial automation environments, this encoder delivers accurate and stable absolute feedback even with long cable runs and electromagnetic interference. Its robust housing and reliable signal output make it well suited for heavy machinery, automated conveyor systems, and process control equipment where consistency and durability are essential.
