What are the key features of SFM-122-L2-ZZ-D-A-K-TR?
- 44-position dual-row SMT socket strip on 1.27 mm (0.050 inch) pitch for high-density fine-pitch interconnects on compact PCBs
- Gold-plated contacts rated 1 A per pin and 150 V AC, designed for high-cycle-life applications requiring low and stable contact resistance
- Tape-and-reel (TR) packaging and polarization key (K) enable automated high-volume pick-and-place assembly with mis-mate protection
What is SFM-122-L2-ZZ-D-A-K-TR used for?
The SFM-122-L2-ZZ-D-A-K-TR suits high-density module-to-baseboard interconnects in space-constrained embedded systems, such as wireless communication modules, industrial IoT gateways, and small-form-factor compute cards. Its fine 1.27 mm pitch allows placement in areas where standard 2.54 mm headers would exceed the available footprint, making it a preferred choice for compact medical wearables and portable test instruments.

Frequently Asked Questions
What pitch and pin count does the SFM-122-L2-ZZ-D-A-K-TR use, and why does pitch matter for board layout?
The SFM-122-L2-ZZ-D-A-K-TR uses a 1.27 mm (0.050 inch) pitch with 44 positions in a dual-row arrangement, giving 22 contacts per row. The tighter pitch compared to standard 2.54 mm connectors roughly halves the footprint length, freeing approximately 25 mm of PCB real estate on a 22-position row for other components.
What are the electrical ratings of the SFM-122-L2-ZZ-D-A-K-TR contacts?
Each contact carries a maximum current rating of 1 A and a working voltage of 150 V AC. The gold-plated contact finish maintains contact resistance below 20 mΩ even after 100 mating cycles, which is important for socketed module designs that are repeatedly inserted and removed during field servicing.
Is the SFM-122-L2-ZZ-D-A-K-TR compatible with SAMTEC TSM or TSMC mating header series?
The SFM series is designed to mate with SAMTEC's TMS and TSM pin header families sharing the same 1.27 mm pitch. Specifically, TSM connectors with a matching 44-position dual-row layout provide a positive 0.2 N insertion force per contact, resulting in approximately 8.8 N total mating force across all 44 pins, well within typical automated assembly tolerances.
