Frequently Asked Questions
How many positions does the SFM-120-02-ZZ-D-A-K-TR provide and at what pitch?
The SFM-120-02-ZZ-D-A-K-TR offers 40 positions in a dual-row configuration at a 0.050" (1.27 mm) pitch. This compact arrangement delivers high contact density within a small SMT footprint, making it suitable for space-constrained board-to-board interconnect designs requiring up to 40 signal connections.
What does the TR suffix indicate about the packaging of the SFM-120-02-ZZ-D-A-K-TR?
The TR suffix designates tape-and-reel packaging, which provides 40-position socket strips in a continuous reel for automated SMT pick-and-place machines. This format supports high-volume PCB assembly, reducing manual handling and enabling consistent placement at 1.27 mm pitch across thousands of boards per production run.
Which application segments commonly use the SFM-120-02-ZZ-D-A-K-TR connector?
This 40-position, 1.27 mm pitch SMT socket strip is widely used in telecommunications line cards, embedded computing boards, and industrial automation equipment. Its dual-row layout enables engineers to route 40 signals between mated boards while maintaining a low board-to-board stacking height appropriate for compact system designs.
How does the SFM-120-02-ZZ-D-A-K-TR compare to a 44-position SFM series variant for a design requiring fewer signals?
When a circuit requires only 40 signals, the SFM-120-02-ZZ-D-A-K-TR is preferable to a 44-position SFM variant because it minimizes the connector footprint by 4 positions at the same 1.27 mm pitch, reducing PCB land pattern area while maintaining dual-row SMT termination and gold-plated contact reliability.
