What are the key features of SMS-102-02-SM-D?
- 4-position dual-row micro socket at 0.050" x 0.100" pitch enables compact through-hole mating in extremely tight PCB footprints
- Precision micro-socket contacts ensure reliable low-resistance mating with compatible micro pin headers across multiple insertion cycles
- Through-hole termination provides robust mechanical retention for applications subject to vibration or repeated connector mating
What is SMS-102-02-SM-D used for?
The SMS-102-02-SM-D is suited for low pin-count through-hole interconnect applications in compact embedded systems, sensor modules, and prototype boards where space efficiency is critical. Its 4-position dual-row configuration at 0.050" x 0.100" pitch is commonly used for modular board stacking, programming interfaces, and debug connectors in dense PCB layouts. The through-hole mounting ensures reliable mechanical stability for connectors subject to repeated mating in lab, industrial, or field-service environments.

Frequently Asked Questions
How many positions does the SMS-102-02-SM-D support, and what is the contact pitch layout?
The SMS-102-02-SM-D is a 4-position dual-row micro socket with a 0.050" x 0.100" pitch. The dual-row arrangement packs 4 contacts into a very compact footprint, making it ideal for minimal-size interconnect applications such as debug ports, programming interfaces, and small sensor module connectors on embedded PCBs.
Why would a designer choose the through-hole SMS-102-02-SM-D over an equivalent SMT micro socket for a compact PCB?
A designer would choose the through-hole SMS-102-02-SM-D when mechanical robustness is prioritized over minimal height, since through-hole solder joints withstand pull forces exceeding 20 N and resist vibration better than SMT alternatives. This makes it preferable for connectors that undergo repeated mating, such as in field-programmable modules or frequently accessed debug interfaces on industrial and embedded boards.
Which prototype or low-volume design scenarios benefit most from the SMS-102-02-SM-D's fine micro-pitch socket format?
Prototype boards, sensor evaluation kits, and small-form-factor embedded modules benefit most from the SMS-102-02-SM-D due to its compact 0.050" x 0.100" dual-row footprint that occupies less than 3 mm x 4 mm of PCB area for just 4 positions. This fine pitch allows designers to incorporate multi-signal connectors in constrained layouts where standard 0.100" pitch single-row sockets would consume too much board space.
