A customized replacement solution can be provided for systems originally equipped with SWM3B-01 and SWM5B-01, with the objective of maintaining the original linear-to-rotary conversion principle and mechanical installation concept. The replacement is designed to fit the existing mounting interface and encoder connection method, allowing direct integration without changes to structural components or control system configuration.
Technically, the replacement units utilize a spring-loaded cable displacement mechanism that converts linear movement into rotational output for incremental or absolute encoders. The measuring stroke is configured to match the longer travel ranges associated with SWM3B-01 and SWM5B-01 applications, ensuring consistent position feedback across the full extension length. Cable tension is maintained by a controlled spring system to support stable measurement behavior and minimize hysteresis during repeated cycles. Mechanical parameters such as permissible cable exit angle, maximum operating speed, and service life are defined to meet industrial motion requirements. The enclosure and sealing design provide protection against dust and incidental moisture, supporting reliable operation in factory automation, material handling, and mobile equipment environments.


In summary, the SWM3B-01 and SWM5B-01 customized replacement solution delivers a technically consistent and robust option for linear position measurement where extended travel lengths are required. By preserving compatibility with existing encoder configurations and installation conditions, it supports long-term operational reliability in demanding industrial applications.
