● Effective for miniaturizing electronics as the pitch between contacts is 1.27 mm.
● Effective against prying and has soft insertion / extraction performance as the terminal structure is ribbon shaped.
● Structured so that the shell side always touches before the contact when coupling in order to prevent damage of the set due to static electricity.
● Secure noise protection can be expected as the cover case and the receptacle shell are robust and made with zinc alloy die-casting which has good shielding effect against electromagnetic waves.
