SWF10B-FK-01 Wire Draw Displacement Converter Solution

A tailored compatible encoder solution can be developed for SWF10B-FK-01 in maintenance, retrofit, replacement, and upgrade applications. This version is built on the same SWF wire draw platform but is configured for a 10 m measuring range, making it suitable for installations where medium travel length and stable cable-to-encoder transmission must be preserved together. Typical production lead time: 15 working days. The engineering task is to keep the original measuring travel, cable winding behavior, and encoder-side mounting continuity intact.

Technical Overview of the SWF10B-FK-01 Encoder

The SWF10B-FK-01 is a cable-type displacement converter that translates linear cable movement into a proportional rotary movement for a connected encoder. The spring drive keeps the cable under constant tension, while the measuring drum moves axially to ensure precise wrap-by-wrap rewinding in its helical groove. This mechanical arrangement supports repeatable displacement conversion and helps avoid slack-induced measurement deviation.

In this coded version, the measuring range is 10 m and the standard bellows-equipped cable entry is included. The converter uses an anodized aluminium housing and a plastic spring housing, while the cable is made from highly flexible stranded stainless steel. For the 10 m version, the cable diameter remains 1.3 mm. The nominal drum circumference is 333 mm.

Industrial Integration Considerations

For a 10 m wire draw system, cable path control becomes more important because the installed travel distance is longer and routing discipline has greater influence on long-term measurement behavior. The datasheet explicitly states that the cable must be extracted rectilinearly relative to the housing and that the cable exit should face downward or sideways. These conditions should be preserved during replacement work to maintain correct winding and avoid lateral deflection.

The 10 m version also introduces different motion characteristics compared with the 5 m model. Its mass is 4 kg, maximum cable speed remains 12 m/s, and maximum cable acceleration is 60 m/s². In practical use, this places the model in a middle position between short-travel responsiveness and longer-stroke mechanical stability.

Custom Compatible Encoder Solution

For SWF10B-FK-01, a custom compatible encoder solution should preserve the 10 m travel range, encoder mounting face, bellows-protected cable entry, spring-driven cable tension system, and straight cable extraction geometry. This combination is important because replacement success depends on whether the system can maintain both its original measuring stroke and its existing installation conditions in the field.

The platform supports mounting of compatible absolute, incremental, and analogue encoders with 58 mm synchro flanges. If the original system includes additional accessories such as a deflection roller, prolongator, brush case, grease chamber, or special protective coating, those items should be verified during engineering review so the final configuration stays aligned with the application environment.

Lead Time and Custom Development

Typical production lead time: 15 working days.

Custom development should review measuring range, encoder compatibility, cable exit position, cable routing straightness, and any accessory-based site adaptations. Since the converter and encoder are generally supplied as one unit, but can also be supplied separately on request, the final arrangement should be confirmed against the original installation concept before production release.
