MCX Snap-On Jack for 6 GHz Signal Paths
The 919-431J-51S: The snap-on fastening gives quick connect-disconnect cycles — rated for 500 mates — which makes this a natural fit for test ports, antenna feeds, or any RF interconnect that sees regular field reconnection.
500 Mating Cycles — Built for Reconnect Duty
A snap-on MCX that carries a 500-cycle rating is specced for equipment that gets mated and unmated repeatedly — field-test harnesses, portable radios, or bench-top RF modules where the connector sees daily use. The gold-on-gold contact interface (centre contact and body finish both gold) prevents the fretting corrosion that would otherwise degrade contact resistance over those cycles.
The mounting type is board edge with a cutout, surface mount. That means the PCB needs a slot or notch at the edge so the connector body sits partly through the board — the shield solder tabs land on top-side pads while the connector extends past the board edge. This is a specific mechanical feature: the enclosure must have clearance for the protruding jack body, and the cutout dimensions in the manufacturer's drawing must match the PCB outline. Not a standard through-hole or SMT footprint — confirm the cutout geometry before committing the board.
