What are the key features of SMS-102-01-SM-D?
- 4-position dual-row micro socket at 0.050" x 0.100" (1.27 mm x 2.54 mm) mixed pitch for ultra-compact board-to-board interconnects
- Through-hole solder mounting provides robust mechanical retention suitable for vibration-prone environments
- Low-profile socket body minimizes total stack height when mated with corresponding Samtec micro pin headers
- Compatible with Samtec SMM series micro pin headers enabling a proven matched mating system with controlled contact force
What is SMS-102-01-SM-D used for?
The SMS-102-01-SM-D is used in compact embedded module-to-baseboard interconnects where a 4-position dual-row micro socket at 0.050" x 0.100" pitch must occupy minimal board area. Through-hole mounting suits wearable electronics, compact IoT sensor nodes, and small-form-factor embedded platforms where vibration resistance is required and board real estate is under 5 mm x 5 mm per connector footprint. The matched micro pitch enables high-density multi-connector layouts on miniaturized PCBs.

Frequently Asked Questions
What is the contact pitch of the SMS-102-01-SM-D and how does it accommodate both axes on the PCB?
The SMS-102-01-SM-D uses a mixed pitch of 0.050" (1.27 mm) in one axis and 0.100" (2.54 mm) in the other, providing 4 contact positions in a dual-row through-hole configuration. This mixed pitch allows fine row spacing while maintaining standard 0.100" column spacing compatible with common PCB drill patterns.
Why choose through-hole mounting for the SMS-102-01-SM-D rather than an SMT micro socket in vibration-prone applications?
Through-hole solder joints penetrate the full PCB thickness and are mechanically anchored by the barrel plating, resulting in pull-out forces typically 3 to 5 times higher than equivalent SMT solder joints. For applications subject to shock above 50 G or continuous vibration, such as UAV avionics or industrial motor-drive modules, through-hole mounting significantly reduces risk of joint fracture under mechanical load.
What mating plug is compatible with the SMS-102-01-SM-D for a complete board-to-board interconnect solution?
The SMS-102-01-SM-D is designed to mate with Samtec SMM series micro pin headers at the matching 0.050" x 0.100" pitch. This family provides a controlled 4-position mating interface with a specified contact normal force that ensures low contact resistance below 20 mΩ over the rated number of mating cycles.
How compact a PCB footprint does the SMS-102-01-SM-D require, and where is it most commonly used?
With only 4 positions and a 0.050" x 0.100" mixed pitch, the SMS-102-01-SM-D occupies a footprint of approximately 2.54 mm x 1.27 mm for the contact array, making it one of the smallest through-hole dual-row sockets available. It is commonly found on miniaturized sensor modules, wearable health monitors, and compact plug-in computing modules where multiple connectors must fit within a 10 mm x 10 mm area.
