Ama-slip ring ayizixhumi ezijikelezayo, ezifanele kakhulu amadivayisi adinga ukuzungeza nokudlulisa amasignali ngesikhathi esifanayo. Kodwa-ke, ngezinye izikhathi ngesikhathi sokusebenza kwemishini, kungase kube nokuphambuka kwesignali. Lokhu kungenxa yokuthi isignali yendandatho yokushelela iyaphazanyiswa. Abakhiqizi bendandatho yokushelela abalandelayo bazokutshela izizathu zokuphazamiseka kwesignali yendandatho yokushelela.
Kunezizathu ezimbili eziyinhloko zokuphazamiseka kwezimpawu zendandatho ezishelelayo, esinye inkinga yentambo, kanti esinye inkinga yesakhiwo sangaphakathi.
Kudingeka kudluliselwe izimpawu ezahlukene, futhi kusetshenziswa izintambo ezahlukene. Izimpawu eziningi ziyazwela futhi zidinga izintambo ezikhethekile, futhi umphumela wokuvikela isignali kumele wenziwe kahle, ngaphandle kwalokho kuzoba nokulahleka kwesignali noma ukukhuluma nge-crosstalk. Abakhiqizi bendandatho yokushelela bakhumbuza ukuthi izimpawu zokudlulisa ezisetshenziswa kakhulu zendandatho yokushelela yizibonakaliso zokushintsha/zokulawula, izimpawu ze-RS485/232, izimpawu zevidiyo, izimpawu ze-pulse eziphansi, izimpawu zokumelana nokushisa, izimpawu ze-strain gauge, izimpawu ze-VGA, izimpawu ze-solenoid valve, izimpawu ze-Profibus, izimpawu ze-encoder, izimpawu zezinga le-TTL, izimpawu ze-Canbus, izimpawu ze-100M/1000M Ethernet nezinye izimpawu.
Uma indandatho yokushelela ingavikelwe endaweni eyisihluthulelo, izobangela ukukhuluma ngesignali. Abakhiqizi bendandatho yokushelela bakhumbuza ukuthi ukuphazamiseka kwesignali kufanele kunakwe ngokukhethekile eduze kwendandatho yamandla, ngoba insimu yamagnetic eduze kwendandatho yamandla izokwenza ukuthi kuphazanyiswe ezinye izimpawu. Lokhu kudinga abakhiqizi bendandatho yokushelela banake ukuhlukaniswa nokuvikelwa phakathi kwezibonakaliso zangaphakathi zendandatho yokushelela, futhi basebenzise izintambo ezikhethekile zezibonakaliso ezikhethekile ukuqinisekisa ukuthi isignali ayilahleki noma ayixhunywanga.
