The present invention provides a digital cable extension transducer, which is an integral structure of a spool, a spiral spring, a cable guide assembly and a magnet-detecting element for directly sending out a digital signal of a displacement of the monitored object. A circuit board is mounted on a bottom plate of the housing for further data transmission. With the pulleys in the cable guide assembly, the cable extends and winds orderly around the spool. A baffle is provided for shielding both the spool and three pulleys of the cable guide assembly, thereby, to prevent the extended cable derailing from the pulleys when the extended cable releases at high acceleration or loosens by accident.
