What are the key features of SFM-148-02-L-D-K-TR?
- 96-position dual-row layout on 0.050 inch (1.27 mm) pitch delivering 192 total contacts on an ultra-compact PCB footprint
- Keying (K) option prevents incorrect mating orientation, eliminating assembly errors in dense multi-connector designs
- Tape-and-reel (TR) packaging compatible with high-speed pick-and-place for production-scale SMT assembly
What is SFM-148-02-L-D-K-TR used for?
The SFM-148-02-L-D-K-TR is used in high-density compute modules, FPGA carrier boards, and large-scale SOM (System-on-Module) platforms that require 96 or more signal connections between stacked PCBs. The keying feature ensures correct orientation in chassis where multiple identical connectors are placed in proximity, preventing board damage during insertion. The tape-and-reel format supports automated production assembly for telecom, aerospace, and data-center edge-computing hardware.

Frequently Asked Questions
How does the K (keying) option on SFM-148-02-L-D-K-TR prevent mis-mating in multi-connector designs?
The K suffix adds a mechanical polarization key to the 96-position connector housing that physically blocks insertion into non-keyed or differently keyed sockets. In designs with multiple SFM connectors placed within 5 mm of each other on the same board, keying ensures each connector can only mate with its designated counterpart, preventing the board damage and electrical faults that would result from swapped connections carrying different voltage rails or signal protocols.
What board stacking height does the low-profile (L) version of SFM-148-02-L-D-K-TR achieve?
The low-profile (L) contact option in the SFM series reduces the mated stack height compared with standard or high-profile variants, typically achieving a board-to-board spacing between 1.5 mm and 3 mm depending on the mating header selected. This is critical in compact chassis where total z-height must remain below 5 mm for the stacked assembly to fit within enclosure constraints.
For a 192-signal FPGA I/O expansion board, is SFM-148-02-L-D-K-TR a cost-effective single-connector solution?
Yes. Using one SFM-148-02-L-D-K-TR instead of multiple smaller connectors reduces BOM line items, simplifies PCB routing by concentrating all 192 contacts into one 48-mm body, and lowers assembly labor. The tape-and-reel format also enables volume pricing advantages for production quantities of 1,000 units or more, making it a cost-effective choice for FPGA I/O expansion, backplane interface, and data-acquisition mezzanine cards.
