SMP Plug for mmWave Signal Paths
The SMP-PL-P-GF-ST-TH2: The snap-on fastening type gives a quick blind-mate connection — the limited detent feature means lower axial retention than a full-detent variant, so it suits board-level test points or modular RF assemblies where you need to unmate by hand without a tool.
Limited Detent vs Full Detent — Which SMP Plug Fits Your Vibration Budget
The SMP-PL-P-GF-ST-TH2 carries a limited detent feature, while the SMP-PF-P-HE-ST-EM3 uses a full detent. Limited detent means a lower push-on / pull-off force — easier to mate and unmate repeatedly in a lab or test fixture, but it will not hold as firmly under sustained vibration. Full detent gives higher axial retention for applications like airborne or vehicle-mounted RF modules where the connector must stay mated through shock and vibration. Both are 50 Ohm, 40 GHz, male pin SMP plugs with gold-plated brass bodies and through-hole solder terminations — the detent choice is the deciding factor for the mechanical environment.
