What are the key features of SFM-104-02-F-D-A-P-TR?
- 8 positions in dual-row 1.27 mm (0.050 inch) pitch for ultra-compact reliable SMT socket connections
- Polarization peg (P) feature ensures correct mating orientation and prevents mis-insertion on small 8-position connectors
- High-reliability design with beryllium copper contacts and gold plating for consistent low-resistance mating
What is SFM-104-02-F-D-A-P-TR used for?
SFM-104-02-F-D-A-P-TR is used in small plug-in sensor modules, SPI or I2C peripheral daughter cards, and compact memory module sockets where only 8 positions are required at a 1.27 mm pitch. The polarization peg prevents reverse insertion in densely populated PCBs where visual verification is difficult. It also suits wearable electronics and portable medical devices requiring a reliable, keyed SMT socket with a minimal footprint.

Frequently Asked Questions
How does the polarization peg (P) in SFM-104-02-F-D-A-P-TR prevent mis-mating on a crowded PCB?
The polarization peg is a mechanical post on the connector body that mates with a corresponding keying hole in the mating header. For an 8-position dual-row connector at 1.27 mm pitch, where all positions are physically identical, this peg is the only physical feature blocking incorrect 180-degree reversed insertion. It reduces rework risk in high-density assemblies where 8-pin connectors are close to other similar components.
What board space does SFM-104-02-F-D-A-P-TR occupy compared to an equivalent 2.54 mm pitch socket?
At 1.27 mm (0.050 inch) pitch, the SFM-104-02 dual-row 8-position socket spans approximately 5 mm in length and 2.54 mm in width. An equivalent 2.54 mm pitch 8-position dual-row connector would require roughly 10 mm in length, making the SFM-104 solution approximately 50% more compact in the pitch direction, which is significant for wearable or handheld device PCBs.
For a portable sensor module requiring 8 signals at 1.27 mm pitch, when is SFM-104-02-F-D-A-P-TR preferable to a single-row 8-position socket?
A dual-row 8-position socket provides a shorter connector length than a single-row 8-position connector at the same pitch. The SFM-104-02's dual-row configuration reduces connector length by approximately 50%, fitting within tighter PCB outline constraints. The added board area saved in the length dimension can accommodate routing channels for the 8 signal lines without requiring additional PCB layers.
