Frequently Asked Questions
What is the total contact count and row configuration of the SFM-136-L2-FM-D-K-TR?
The SFM-136-L2-FM-D-K-TR provides 72 contacts arranged in a dual-row (2×36) configuration on a 0.050" (1.27 mm) pitch, enabling high-density routing of 72 signals across a surface-mount footprint under 50 mm in length.
How does the keyed feature on the SFM-136-L2-FM-D-K-TR prevent assembly errors?
The keyed alignment feature physically prevents insertion of an un-keyed or incorrectly oriented mating header, reducing mis-mating risk in production environments. This is especially valuable in 72-pin high-density connectors where incorrect insertion could damage up to 72 signal lines simultaneously.
Which SAMTEC pin headers mate with the SFM-136-L2-FM-D-K-TR for board-to-board stacking?
The SFM-136-L2-FM-D-K-TR mates with SAMTEC TFM and TSM series pin headers on a 1.27 mm (0.050") pitch, supporting board-to-board stacking heights typically ranging from 4 mm to 15 mm depending on the selected header mating length.
Is the SFM-136-L2-FM-D-K-TR suitable for high-volume automated PCB assembly?
Yes, the -TR suffix denotes tape-and-reel packaging compatible with standard SMT pick-and-place machines. The surface-mount termination allows reflow soldering at standard lead-free profiles up to 260°C, making it suitable for high-volume automated production.
