Frequently Asked Questions
What is the pitch and row configuration of the SFM-103-T2-STL-D-K-TR?
The SFM-103-T2-STL-D-K-TR uses a 0.050" (1.27 mm) pitch in a dual-row arrangement, providing 6 total positions (3 per row). This compact footprint allows high-density signal routing on boards where space is limited to under 5 mm in connector width.
Which industrial or avionics designs benefit from the stainless steel locking feature on this connector?
Applications subject to vibration or shock, such as avionics, robotics, and industrial motor-drive enclosures, benefit most from the stainless steel locking mechanism. The lock maintains mated contact resistance below 20 mΩ even under 15 G vibration loads, preventing intermittent signal loss on critical 3.3 V or 5 V logic lines.
How does the TR tape-and-reel packaging affect assembly throughput for the SFM-103-T2-STL-D-K-TR?
Tape-and-reel (TR) packaging is compatible with standard 8 mm or 12 mm pick-and-place feeders, allowing placement at rates exceeding 3000 components per hour on modern SMT lines. This eliminates manual loading, reduces placement errors, and supports high-volume production runs where lead times must stay under 2 weeks per batch.
When would SFM-103-T2-STL-D-K-TR be selected over a through-hole equivalent socket strip?
Surface-mount SFM connectors save at least 1.5 mm of board thickness compared to through-hole variants, making them preferred for designs targeting a PCB stack height under 10 mm. They also eliminate drilling costs and allow double-sided component placement, cutting total board area by up to 20% in dense 6-layer designs.
