This OEM replacement for the DAF58-12B18 is developed as a customized 1:1 alternative, accurately matching the original 4–20 mA absolute output and mechanical mounting interface. The design allows direct installation into existing systems without electrical recalibration or mechanical modification. By leveraging a flexible non-standard production process, this solution helps reduce replacement cost while significantly shortening lead time, with delivery typically completed within 15 working days.
The replacement encoder is optimized for stable current-loop transmission, ensuring reliable absolute position feedback over long cable distances and in environments with electromagnetic interference. Performance remains consistent under continuous operation, supporting long-term system accuracy. Low-volume and application-specific customization can be accommodated, making this OEM replacement suitable for automated material handling, assembly machinery, and process control systems that require fast availability, compatibility, and dependable analog feedback.
