Frequently Asked Questions
What does the keyed feature on the TSM-128-03-S-DH-A-K-TR prevent during PCB assembly?
The keyed housing on the TSM-128-03-S-DH-A-K-TR prevents incorrect mating orientation during assembly, ensuring all 56 positions are properly aligned before connection. This is critical in dual-row 0.100" pitch connectors where reversing the connector could damage signals or power rails in industrial control and embedded computing applications.
How does the dual-height (DH) configuration of the TSM-128-03-S-DH-A-K-TR benefit board stacking designs?
The dual-height configuration allows the TSM-128-03-S-DH-A-K-TR to mate with boards at two different stacking heights, increasing design flexibility for backplane systems and expansion cards. With 56 positions at 0.100" pitch, engineers can route high-channel-count signals between boards with customizable board-to-board spacing in compact multi-board assemblies.
Is the TSM-128-03-S-DH-A-K-TR available in tape-and-reel for automated assembly lines?
Yes, the TSM-128-03-S-DH-A-K-TR is packaged in tape-and-reel format as indicated by the TR suffix, making it compatible with standard automated pick-and-place equipment. The tape-and-reel format supports reliable component placement for the 56-position, 0.100" pitch surface mount terminal strip during high-volume reflow soldering production runs.
