What are the key features of TSM-129-04-STL-DH-A-K-TR?
- 58 positions dual-row at 0.100" (2.54 mm) pitch in a shrouded SMT package for protected high-density board interconnect
- STL shroud with dual-height (DH) housing and A-type alignment key prevents incorrect connector mating in multi-connector PCB layouts
- Tape-and-reel (TR) packaging enables high-throughput automated pick-and-place SMT assembly in volume production
What is TSM-129-04-STL-DH-A-K-TR used for?
The TSM-129-04-STL-DH-A-K-TR is suited for high-density board-to-board interconnect in embedded computing systems, industrial I/O modules, and communication backplane cards requiring 58 signals at 0.100" pitch. The shrouded dual-height housing and alignment key prevent mismatched mating across multi-connector panels, reducing assembly errors in complex systems. Tape-and-reel delivery supports automated placement in high-volume SMT production lines with consistent positional accuracy.

Frequently Asked Questions
How many positions does the TSM-129-04-STL-DH-A-K-TR provide, and at what pitch?
The TSM-129-04-STL-DH-A-K-TR offers 58 positions in a dual-row SMT configuration at 0.100" (2.54 mm) pitch. This makes it suitable for board-to-board signal interfaces in embedded computing, industrial automation, and communication line cards where 58 simultaneous connections are needed in a compact surface-mount form factor.
How does the A-K alignment key on TSM-129-04-STL-DH-A-K-TR prevent mating errors in multi-connector PCB assemblies?
The A-type alignment key (K suffix) provides a physical polarization feature that allows the correct mating header to engage at 0.100" pitch while preventing incorrect orientation or cross-mating with adjacent 58-position connectors. This is particularly valuable on backplane panels or daughtercard assemblies with multiple side-by-side connectors that could otherwise be swapped during field installation.
Which production format does TSM-129-04-STL-DH-A-K-TR come in, and why does it matter for volume SMT manufacturing?
The TSM-129-04-STL-DH-A-K-TR is supplied in tape-and-reel (TR) packaging, which feeds directly into automated pick-and-place machines used in SMT reflow lines. For high-volume PCB production requiring consistent 58-position connector placement at 0.100" pitch, TR packaging reduces manual handling, improves placement accuracy, and supports faster production cycle times.
