The HR30 is a push-pull latched circular connector designed to meet IP67, enabling it to withstand submersion for up to 30 minutes when mated.
This miniature circular connector has an outside diameter of 12.6 mm, housing six contacts in a lightweight plastic that is totally resistant to corrosion. Both the plug and receptacle use gold plated solder cup contacts, rated at 2 amps. HR30 connectors with 3, 10, and 12 contacts are in development.
Mis-insertion can be avoided due to its five-key polarization system. The HR30 is also designed to withstand 1000 cycles. Behind the plug's collet-style cable strain relief is a 10 mm long gasket to seal the cable; these features are integrated when the shell is screwed into position onto the insulator, and it is achieved without special tools.
