The EV1 series from Hirose is a high current capacity connector that is rated up to 125 A. The waterproof structure is IP67 water-resistant in unmated state when EV1-62RA-3SB, EV1-62RA-2SB are used. It is IP68 / X9K water-resistant in the mated condition. The use of a special rubber component for the internal seal enhances oil and water resistance. The highly reliable contact structure allows for a high current capability, guards against vibration to the contact, and decreases contact resistance. The metal shell enhances EMI shielding. The shell is constructed of an aluminum alloy material enabling it to be lightweight. The contact and connector design protects against accidental electrical shock using IEC 60601 test procedure.
