Draw-wire displacement converter SWP

Product catalog summary
Functional Description: The SWP series cable-type displacement converter utilizes a flexible steel cable, up to 2 meters in length, to convert linear movement into angular movement via a measuring drum. This drum is connected to a conductive plastic potentiometer. A spring drive ensures the cable remains taut, preventing sagging and potential errors. The drum's axial movement on a spindle allows precise cable winding in a helical groove. A brush at the cable entry removes dust.
Environmental Data: The device operates within a temperature range of -20 °C to +50 °C and has a protection class of IP 54. It can withstand shocks up to 25 g and has a life expectancy of approximately 2 million cycles.
Material: The housing is made of anodized aluminum, with stainless steel cable entry and cable. The cap and spring housing are made of black durethan.
Variants A and B with Electronic Circuit: These variants require a current of 80 mA max and a supply voltage of 20 - 30 V. Signal outputs are 0 ... 20 mA for Variant A and 4 ... 20 mA for Variant B, with a linearity of ± 0.2%.
Mechanical Data: The measuring range is either 1 or 2 meters, with a spring force of approximately 4 N at the start and a spring constant of ~2.5 N/m. The maximum speed is 10 m/s, and the cable diameter is 0.55 mm. The thermal coefficient is 0.01 mm/mK, and the maximum acceleration is 70 m/s². The device weighs approximately 0.6 kg.
Connections for Variants A and B: Contact A is for +24 V supply, B for 0V, C for output 0(4)...20 mA, D and F are not connected, and E is for screening not connected. The counter plug STR6GS20 is ordered separately.
Order Code Format: The format is SWP 2 - 2000 - A 01, with special variants A (0 - 20 mA), B (4 - 20 mA), and P (Potentiometer).
Variant P without Electronic Circuit: This variant has a resistancy of 5 k Ohm ± 10%, power dissipation of 1.5 W max, and linearity of ± 0.2%.
Dimensions: Detailed dimensions are provided for both 1 m and 2 m cable lengths, with connector covers that can be displaced by 90° or 180°.

Draw-wire displacement converter SWP-1

Cable-type displacement converter SWP series with potentiometric sensor SWP 11201 FE 06 / 2016 Functional description The linear movement of a flexible steel cable, which can have a length of up to 2 m, is converted into an angular movement with the aid of a measuring drum. The measuring drum is coupled via a gear to a conductive plastic potentiometer. The restoring force of the spring drive holds the measuring cable tight at all times and prevents any sagging which would otherwise induce an error. The measuring drum moves axially on a spindle ensuring that the cable is wound up precisely and reproducibly wrap for wrap in the helical groove of the drum. The cable entry contains a brush to remove dust.
