125A High-Current Waterproof Connectors EV Series Derating Curve Current A Fig.1 Features Temperature Rise Curve 1. Scre w Cramp Reliable lock by screw and nut. Superior anti- vibration performance by mounting to chassis. 2. Waterproof Structure The EV series is IP67 water resistant in unmated state (when EV1-62RA-3SB, EV1-62RA-2SB is used). It is IP68/X9K water resistant in mated. The use of special rubber component for the internal seals enhance oil and water resistance. 3. Standard Tool for Contact Assembly Contacts can be crimped using readily available JIS standard tools (JIS C 9711). 4. Downsizing Current A Staggered panel flange design saves space. Fig.2 5. Lightweight The shell is constructed of an aluminum alloy material enabling it to be lightweight. Measurement Condition 6. Multi-Point Contact Spring 2 The plug has three contacts where 20 mm electric wires Highly reliable contact structure allows for a high are connected and then covered with a corrugated current capability, guards against vibration to the housing. Measurement was taken by connecting copper contact and decreases contact resistance. bus bars of 3 mm x 12 mm to the three contacts of the receptacle and wiring in series. 7. Shielded Design The metal shell enhances EMI shielding. Remarks 8. Finger Protection Derating curve and temperature rise curve changes Contact and connector design protects against slightly by a given cable that is being used and slight accidental electrical shock using IEC 60601 test variations occur under the same conditions. Therefore, procedure. the values indicated above are reference values and not guaranteed values. In cases where the application will demand a high level of reliability, such as automotive, 1 2015.7e please contact a company representative for further information.
