Key Features
- 4-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch providing 2 contacts per row for minimal-footprint board-to-board connections
- Low-profile (L) housing minimizes stack height for slim product designs where vertical board clearance is below 5 mm
- Gold-plated contacts (K suffix) and tape-and-reel (TR) packaging enable high-reliability automated assembly in fine-pitch SMT production
Applications
The SFM-102-L2-L-D-A-K-TR is ideal for minimal pin-count module-to-board interfaces, configuration jumpers replaced by positive-retention socket headers, and compact sensor module attachment requiring only 4 connections at 0.050" pitch. Low-profile and tape-and-reel packaging suit high-volume consumer electronics, wearables, and IoT nodes where board height below 5 mm and automated assembly are essential. Gold contacts ensure reliable connectivity even in applications subject to vibration or repeated mating.

Frequently Asked Questions
How many contacts does SFM-102-L2-L-D-A-K-TR provide and in what configuration?
SFM-102-L2-L-D-A-K-TR provides 4 total positions arranged in 2 rows of 2 contacts each at 0.050" (1.27 mm) pitch. This minimal contact count suits lightweight module attachment, sensor header interfaces, or low-pin-count board-to-board links where only 4 signals or power connections are needed within a very compact PCB land pattern.
For a slim IoT device with a 3 mm board-to-board gap, why select the low-profile housing of SFM-102-L2-L-D-A-K-TR?
The low-profile (L suffix) housing of SFM-102-L2-L-D-A-K-TR is designed for board-to-board stacking heights as low as 3 mm to 4 mm, fitting within tight enclosures where standard-height sockets would exceed available clearance. This is critical for wearable electronics, compact IoT nodes, and handheld instruments where total assembly thickness budgets are under 10 mm and every millimeter of height matters.
When would SFM-102-L2-L-D-A-K-TR be a better choice than a 4-pin 0.100" pitch socket for sensor attachment?
Choose SFM-102-L2-L-D-A-K-TR over a 0.100" pitch alternative when board space is limited and the PCB land pattern must stay under 3 mm wide for all 4 contacts. At 0.050" (1.27 mm) pitch, the total connector footprint is roughly half the width of a 0.100" (2.54 mm) pitch socket with the same 4 positions, enabling higher routing density on PCBs with less than 5 mm of available width for the interface.
