Frequently Asked Questions
What position count and pitch does the TSM-125-04-L-DH-A-K-TR provide for board-to-board applications?
The SAMTEC TSM-125-04-L-DH-A-K-TR is a 50-position dual-row connector with a 0.100 inch (2.54 mm) pitch, providing 25 positions per row. This configuration delivers a high pin count in a compact footprint, suitable for embedded control boards requiring dense signal and power connectivity.
How does the keying (K) feature on the TSM-125-04-L-DH-A-K-TR prevent assembly errors?
The keying (K) option on the TSM-125-04-L-DH-A-K-TR introduces a physical polarization feature that blocks incorrect insertion of the mating connector. This prevents reverse-polarity connections that could damage sensitive circuitry on a 50-pin interface, reducing rework rates in high-mix PCB assembly and field installation environments.
Why choose the right-angle variant (L) of TSM-125 over a vertical variant for edge-access designs?
The right-angle (L) orientation of the TSM-125-04-L-DH-A-K-TR positions mating access parallel to the PCB surface, reducing total assembly height and enabling panel-mount or front-access cabling. This is important in 1U rack enclosures or compact industrial terminals where vertical connector height above the board exceeds a 15 mm clearance limit.
How does tape-and-reel packaging improve assembly efficiency for the TSM-125-04-L-DH-A-K-TR?
Tape-and-reel (TR) packaging for the TSM-125-04-L-DH-A-K-TR feeds parts directly into SMT pick-and-place machines at rates compatible with high-throughput production lines. This eliminates manual feeder loading for 50-pin connectors, reduces placement cycle time to under 2 seconds per part, and supports consistent orientation accuracy across thousands of boards per production shift.
