What are the key features of SFM-141-L2-ZZ-D-A-K-TR?
- 82-position dual-row socket at 0.050-inch pitch provides maximum signal density within a compact SMT footprint
- Long-wipe (L2) contact geometry increases mating contact area, improving reliability and reducing contact resistance across repeated insertions
- Keying (K suffix) prevents incorrect connector mating orientation, protecting signal integrity in multi-connector assemblies
What is SFM-141-L2-ZZ-D-A-K-TR used for?
The SFM-141-L2-ZZ-D-A-K-TR is designed for high-pin-count mezzanine and module interfaces in FPGA carrier boards, test and measurement equipment, and high-performance embedded computing where 82 signals must be reliably routed at 0.050-inch pitch. The long-wipe contact geometry ensures sustained low contact resistance through hundreds of mating cycles, supporting hot-swap compute modules and removable I/O cards. Its keying feature makes it a dependable choice for multi-board assemblies in industrial and military avionics environments where mis-mate prevention is critical.

Frequently Asked Questions
How many contact positions does SFM-141-L2-ZZ-D-A-K-TR offer and over what connector span are they distributed?
The SFM-141-L2-ZZ-D-A-K-TR contains 82 positions in 2 rows at a 0.050-inch (1.27 mm) pitch, spanning approximately 2.1 inches of board edge. This makes it one of the higher-density options in the SAMTEC SFM series, suitable for interfaces requiring more than 80 signals without moving to a larger pitch.
What advantage does the L2 long-wipe contact in SFM-141-L2-ZZ-D-A-K-TR offer over standard-wipe contacts?
The L2 long-wipe contact geometry on the SFM-141-L2-ZZ-D-A-K-TR provides a greater contact surface overlap during mating compared to standard-wipe versions. This translates to lower initial contact resistance — typically below 20 mΩ — and more stable electrical performance after 100 or more mating cycles, which is essential in removable module and test-socket applications.
In which production scenario does the tape-and-reel (TR) format of SFM-141-L2-ZZ-D-A-K-TR reduce assembly cost most effectively?
The TR packaging of the SFM-141-L2-ZZ-D-A-K-TR is most cost-effective in medium to high-volume SMT production runs where reels of 500 to 2000 parts feed directly into automated pick-and-place machines without operator handling. Eliminating manual loading reduces placement errors and can cut per-board labor cost by several cents per connector position, a meaningful saving on assemblies with 4 or more connectors.
