Frequently Asked Questions
What is the pitch and contact count of the SEM-119-02-03.0-G-D, and how does that compare to larger-pitch alternatives?
The SEM-119-02-03.0-G-D provides 38 positions at a 0.80 mm pitch in a dual-row configuration, delivering 19 pins per row. This is significantly denser than 1.00 mm or 1.27 mm pitch alternatives, reducing connector footprint area by up to 37% and enabling compact board-to-board interfaces in space-critical designs.
What benefit does the Micro Tiger Eye contact design provide in the SEM-119-02-03.0-G-D?
The Micro Tiger Eye contact geometry provides a multi-point wiping action during mating, creating multiple contact points per pin at 0.80 mm pitch spacing. This reduces effective contact resistance, clears surface contamination during insertion, and maintains reliable electrical connection under mechanical shock and vibration environments typical in portable or wearable device applications.
Why are gold-plated contacts important for the SEM-119-02-03.0-G-D in low-signal-level applications?
Gold plating on the SEM-119-02-03.0-G-D contacts prevents oxidation and ensures low and stable contact resistance across thousands of mating cycles at signal levels as low as a few millivolts. This is critical in high-speed differential signal and low-level analog interfaces common in medical, instrumentation, and sensor module applications using 0.80 mm pitch connectors.
Which mating plug connector is compatible with the SEM-119-02-03.0-G-D?
The SEM-119-02-03.0-G-D mates with SAMTEC SEM-series plug headers or compatible 0.80 mm pitch dual-row board connectors. The matched 38-position pair provides a controlled mating force and a board-stacking height determined by the 3.0 mm specified standoff, enabling precise module stacking heights in layered embedded system assemblies.
