Frequently Asked Questions
What is the contact pitch of SMS-102-01-G-D and how many positions does it have?
The SMS-102-01-G-D is a 4-position micro socket with a hybrid pitch of 0.050" (1.27 mm) x 0.100" (2.54 mm), allowing dense signal routing in a very small PCB footprint. This pitch combination is common in compact embedded modules where board space is at a premium and reliable signal integrity across 4 contacts is required.
What gold plating thickness does SMS-102-01-G-D use, and why is it specified with a nickel barrier?
The SMS-102-01-G-D uses 10 µin of gold plating over a 50 µin nickel barrier on the mating contacts. The nickel barrier acts as a diffusion layer that prevents base metal migration into the gold, preserving low and stable contact resistance over time and across repeated mating cycles, which is critical for reliable signal performance in production environments.
In which PCB designs is a 4-pin micro socket like SMS-102-01-G-D typically preferred over a standard 0.100" socket?
A 4-pin micro socket with 0.050" x 0.100" pitch is preferred in space-constrained PCB designs such as wearable devices, sensor breakout boards, and miniaturized embedded systems where a standard 0.100" pitch socket would occupy too much board area. The fine pitch allows 4 signals to be routed in a footprint roughly 50% smaller than a conventional 4-pin 0.100" connector, enabling denser PCB layouts.
