What are the key features of SFM-102-L2-H-D-A-P?
- 4-position dual-row SMT socket strip on 0.050" (1.27 mm) pitch providing 4 signals in one of the smallest SFM series footprints available
- High-profile (H) contact standoff provides additional board clearance for components beneath the connector or thicker PCB stackup configurations
- High reliability gold-plated contacts maintain low contact resistance and consistent mating performance over extended lifecycles
- Dual-row configuration delivers 4 signals in roughly half the PCB length of a comparable single-row strip
What is SFM-102-L2-H-D-A-P used for?
The SFM-102-L2-H-D-A-P is ideal for ultra-compact daughter-card and micro-module interfaces in medical devices, wearables, and miniaturized industrial sensors where only 4 signal lines need to cross a board-to-board interface at 0.050" pitch. Its high-profile contact standoff suits applications with components mounted directly beneath the connector, requiring a clearance gap between the mating PCBs. The high reliability construction ensures consistent performance in demanding environments with extended mating cycle requirements.

Frequently Asked Questions
How compact is the SFM-102-L2-H-D-A-P and what does the 4-position dual-row layout mean for PCB footprint?
The SFM-102-L2-H-D-A-P provides 4 contact positions in a 2-row, 2-contacts-per-row layout on a 0.050" (1.27 mm) pitch. The resulting footprint is extremely compact, spanning approximately 2.54 mm in length along the contact row direction, making it one of the smallest available high-reliability SMT socket strips and suitable for micro-module designs where every square millimeter of PCB space is critical.
What does the H (high-profile) designation mean for the SFM-102-L2-H-D-A-P and when should it be chosen over a standard profile?
The H designation on the SFM-102-L2-H-D-A-P refers to a high-profile contact variant that provides a greater board-to-board separation distance compared to standard-height socket strips. This extra standoff height — typically 2 mm or more above the PCB surface — is selected when components such as capacitors, resistors, or ICs are mounted directly beneath the socket area on the underside of the mating daughter card, requiring clearance to avoid mechanical interference during mating.
In which miniaturized product designs is a 4-position 0.050" pitch socket like the SFM-102-L2-H-D-A-P the right connector choice?
A 4-position 0.050" pitch socket like the SFM-102-L2-H-D-A-P is the right choice for miniaturized product designs such as medical implant accessories, compact sensor modules, and small wireless communication add-on boards where the interface carries only 4 signals — for example, I2C (SCL, SDA, VCC, GND) or SPI (MOSI, MISO, SCK, CS). The combination of only 4 pins and the 0.050" pitch keeps the connector body length under 3 mm.
How does the SFM-102-L2-H-D-A-P compare to through-hole 4-position connectors for low-volume prototyping versus production?
For low-volume prototyping, a through-hole 4-position connector on a 0.100" pitch is often simpler to hand-solder and easier to align. However, the SFM-102-L2-H-D-A-P's 0.050" pitch SMT design is preferred when board space is limited to less than 3 mm in connector length or when the production volume exceeds several hundred units and reflow soldering will be used. The SMT mounting also reduces layer routing congestion by eliminating via barrels for 4 signal nets.
