What are the key features of TSM-129-02-L-DH-A-K-TR?
- 58 positions in dual-row .100" (2.54 mm) pitch configuration for high-density PCB signal routing
- Gold-plated (A-suffix) contacts for superior conductivity and corrosion resistance in demanding environments
- Through-hole anchor pins (K-suffix) provide mechanical retention supplementing the SMT solder joints
- Tape-and-reel (TR) packaging compatible with automated pick-and-place assembly
- Low-profile SMT terminal strip design suitable for space-constrained board-to-board applications
What is TSM-129-02-L-DH-A-K-TR used for?
TSM-129-02-L-DH-A-K-TR is used in telecommunications backplanes, high-speed data acquisition boards, and industrial control systems where 58-position dual-row connectivity with gold contacts is required. The anchor-pin retention feature makes it well suited for applications subject to vibration or mechanical stress, such as ruggedized computing and embedded systems.

Frequently Asked Questions
How does the gold contact plating in TSM-129-02-L-DH-A-K-TR improve performance over tin-plated alternatives?
The gold-plated contacts (A-suffix) in TSM-129-02-L-DH-A-K-TR provide lower contact resistance and better corrosion resistance than tin alternatives. This is especially important for 58-position dual-row connectors in applications where stable signal integrity must be maintained across hundreds of mating cycles and operating temperatures from -55°C to +125°C.
What purpose do the anchor pins (K-suffix) serve in the TSM-129-02-L-DH-A-K-TR?
The K-suffix designates through-hole anchor pins that mechanically lock the SMT strip to the PCB during reflow soldering and in the final assembly. This extra retention is critical for 58-position connectors in vibration-prone environments, reducing the risk of pad lift at any of the dual-row .100" positions.
Which PCB assembly process is TSM-129-02-L-DH-A-K-TR designed for?
TSM-129-02-L-DH-A-K-TR is designed for automated SMT assembly. The TR (tape-and-reel) suffix supports pick-and-place equipment, and the SMT footprint with .100" (2.54 mm) pitch is compatible with standard reflow soldering processes used for dual-row terminal strips in volume production.
How does TSM-129-02-L-DH-A-K-TR compare to TSM-129-02-LM-DH-P-TR for board connections?
TSM-129-02-L-DH-A-K-TR uses gold contacts and anchor pins (K), making it better suited for high-reliability, high-cycle-count applications or harsh environments. TSM-129-02-LM-DH-P-TR uses tin contacts, making it more cost-effective for standard commercial applications with the same 58-position, dual-row .100" pitch footprint.
