Features

EMI Shielding: solid metal-to-metal coupling, grounding fingers, electroless nickel plating, and thicker wall sections provide superior EMI shielding capability of 65dB minimum at 10 GHz
Withstands High Vibration: operates under severe high temperature vibration, through 200°C
Withstands High Impact Shock: excellent resistance shock with no electrical discontinuity and no disengagement of the mated connectors
Contact Protection: recessed pins in this 100 % scoop - proof connector minimize potential contact damage
No Lockwiring: unique, self - locking, quick coupling connector eliminates lockwiring
Quick Coupling: completely mates and self - locks in a 360° turn of the coupling nut
Moisture Resistance: improved interfacial seal design helps prevent electrolytic erosion of contacts
