Frequently Asked Questions
What pitch dimensions does the SMS-109-02-TM-D socket support?
The SMS-109-02-TM-D supports a 0.050 inch by 0.100 inch mixed pitch layout across its 18 positions in a dual-row configuration. This pitch combination accommodates standard 0.050 inch micro header pins while maintaining a 0.100 inch row spacing for mechanical stability during repeated insertions.
How many insertion cycles is the SMS-109-02-TM-D rated for in module-swap applications?
SAMTEC micro sockets of this series are designed to withstand a minimum of 30 mating cycles, with gold-plated contact surfaces maintaining contact resistance below 20 milliohms across the 18 positions. This makes the SMS-109-02-TM-D suitable for applications where daughter modules are frequently swapped.
Which PCB assembly scenarios benefit most from the through-hole mounting of this 18-position micro socket?
Through-hole mounting of the SMS-109-02-TM-D provides superior solder retention in environments subject to mechanical vibration, thermal cycling from -55°C to +125°C, or manual plug-and-play operations. Industrial control boards, FPGA prototyping systems, and embedded test fixtures all benefit from the added mechanical strength of through-hole pins across 18 positions.
