What are the key features of TSM-129-04-F-DH-A-K-TR?
- 58-position dual-row surface mount terminal strip on 0.100 inch (2.54 mm) pitch
- Keying feature (-K) prevents incorrect mating orientation and connector misalignment
- Full insulator (-F) variant for standard profile dual-row SMT applications
- Tape and reel (-TR) packaging supports automated pick-and-place SMT assembly
- Gold-plated contacts provide low contact resistance and extended mating cycle reliability
What is TSM-129-04-F-DH-A-K-TR used for?
The TSM-129-04-F-DH-A-K-TR is designed for embedded computing, industrial I/O, and test system backplanes where a high-density 58-position dual-row SMT interconnect with keying is required. The keying feature prevents incorrect connector insertion, making it valuable in multi-connector systems where similar-looking connectors could be swapped by mistake. Tape-and-reel packaging enables efficient high-volume SMT production on standard pick-and-place equipment.

Frequently Asked Questions
What does the keying feature (-K) add to TSM-129-04-F-DH-A-K-TR compared to non-keyed variants?
The -K keying option adds a polarization feature to the 58-position dual-row connector that physically prevents incorrect mating. In systems with multiple 0.100 inch pitch connectors of similar pin counts, keying ensures the correct receptacle is mated to the correct header, eliminating the risk of reversed or misaligned connections that could damage a 3.3 V or 5 V powered circuit board.
How many signal contacts does TSM-129-04-F-DH-A-K-TR provide, and how are they arranged?
The TSM-129-04-F-DH-A-K-TR has 58 total positions in a dual-row, 0.100 inch (2.54 mm) pitch layout, giving 29 contact positions per row. This dual-row arrangement supports up to 58 simultaneous signal connections in a compact SMT footprint, making it efficient for high-signal-count board interfaces.
What operating temperature range is expected for TSM-129-04-F-DH-A-K-TR in industrial environments?
SAMTEC TSM-series SMT terminal strips are rated for operation from -65°C to 125°C, meeting requirements for industrial automation, transportation electronics, and test equipment applications. This wide temperature range ensures reliable contact performance across typical industrial thermal cycling conditions.
Is TSM-129-04-F-DH-A-K-TR available in tape and reel for automated PCB production?
Yes, the -TR suffix on TSM-129-04-F-DH-A-K-TR designates tape and reel packaging, which is compatible with automated pick-and-place SMT equipment. This packaging format ensures accurate component orientation during placement, reduces manual handling of the 58-position connector, and supports high-volume production with standard SMT reflow assembly profiles up to 260°C.
