What are the key features of SMS-101-02-FM-D?
- 2-position dual-row female micro (FM) through-hole socket at 0.050" x 0.100" pitch provides a minimal-footprint interface for micro-module board-to-board signal connections
- Precision-machined female micro contacts deliver reliable retention and low contact resistance, supporting repeated insertion cycles in prototype and low-volume production assemblies
- Through-hole termination provides strong mechanical anchoring to the PCB, improving connector durability in applications subject to vibration or repeated mating and unmating
What is SMS-101-02-FM-D used for?
The SMS-101-02-FM-D is designed for through-hole micro socket applications in prototype boards, test fixtures, and low-volume embedded assemblies where only 2 signal positions at 0.050" x 0.100" pitch are required. Its compact dual-row footprint allows it to interface directly with corresponding SAMTEC micro headers for board-to-board or wire-to-board connections in miniature sensor, control, and communication modules. The connector is also commonly used in development and evaluation boards where modular plug-in flexibility with small 2-position micro headers is needed.

Frequently Asked Questions
What pitch configuration does SMS-101-02-FM-D use and how does it differ from standard 0.100" pitch sockets?
The SMS-101-02-FM-D uses a 0.050" x 0.100" mixed pitch, with 0.050" spacing between the 2 rows and 0.100" between contact columns within each row. This differs from a standard single 0.100" pitch socket by offering a narrower row-to-row spacing, enabling compact dual-row micro-module interfaces in a footprint smaller than conventional 2.54 mm pitch headers commonly used in development boards.
In which prototype or test applications is a 2-position through-hole micro socket like SMS-101-02-FM-D most practical?
A 2-position through-hole socket such as SMS-101-02-FM-D is most practical in prototype boards, breakout modules, and bench test fixtures where only 2 signals such as I2C SDA and SCL, UART TX and RX, or a single differential pair need to be routed via a removable micro header. Through-hole mounting provides superior mechanical strength compared to SMD alternatives, supporting at least 100 mating cycles in typical development environments.
What mating connectors are compatible with SMS-101-02-FM-D and how does contact plating affect connection reliability?
SMS-101-02-FM-D mates with SAMTEC SMS or TMS series male micro headers sharing the same 0.050" x 0.100" pitch and 2-position dual-row configuration. Gold-plated contacts on the female socket maintain contact resistance below 20 milliohms per pin and resist oxidation over time, ensuring reliable electrical continuity even in prototype assemblies that are repeatedly connected and disconnected across many development iterations.
