Cable-type displacement converter SWM series for use with absolute and incremental encoders n Very robust construction for mechanical engineering and industrial plant application n For converting linear displacements of up to 5 m into a rotary movement n For mounting onto an absolute or incremental encoder n Easy to install and to use n Protection grade IP 65 (IP 54) Functional description The linear movement of a flexible steel cable, which can have a length of up to 5 m, is converted into an rotary movement with the aid of a measuring drum. The measuring drum is connected to the shaft of an encoder. In this way a change in displacement of the measuring cable causes the shaft of the encoder to rotate by a directly proportional amount which can be recorded. Generally encoders and converters are supplied as one unit. Upon request both items are also available as separate units. To load the encoder model series KR, CR and TM are suitable with digital interface, DAF and TM with analog interface and pulse of the series, GIO and GIM TB. Preferably used are those with the flange-58th. 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 cable is wound up precisely and reproducibly wrap for wrap in the helical groove of the drum. The nozzle, through which the cable enters the drum, is protected with a brush and a bellow to prevent water or dust entering the drum. Two roller units at the cable entry allow for up to 20° < deflection of the cable. ) TWK-ELEKTRONIK GmbH Heinrichstrasse 85 info@twk.de www.twk.de
