Frequently Asked Questions
What position count and pitch does the TSM-126-03-TL-DH-A-K-TR offer for board-to-board connections?
The TSM-126-03-TL-DH-A-K-TR provides 52 positions in a dual-row configuration with a 2.54 mm (0.100 inch) pitch. This layout supports high-density signal routing between PCBs while maintaining compatibility with standard 2.54 mm pitch mating connectors used across embedded and industrial designs.
How does the tail style of the TSM-126-03-TL-DH-A-K-TR affect its solder reliability on PCB assemblies?
The through-hole compatible tail design of this connector provides a larger solder fillet area compared to SMT-only tails, improving mechanical pull strength and solder joint reliability. Tails are suited for wave soldering or selective soldering processes with typical peak temperatures up to 260°C, supporting standard RoHS lead-free assembly.
For a 52-signal backplane design, why might the TSM-126-03-TL-DH-A-K-TR be preferred over a single-row connector?
Routing 52 signals through a dual-row connector at 2.54 mm pitch requires approximately half the board edge length compared to a single-row alternative, freeing PCB space for other components. The TSM-126-03-TL-DH-A-K-TR achieves this in a compact footprint that fits common 100 mm card edge zones while maintaining reliable contact performance up to 250 V.
In which embedded or industrial systems is the TSM-126-03-TL-DH-A-K-TR most commonly deployed?
This connector is frequently used in industrial automation backplanes, embedded processor daughter cards, data acquisition modules, and laboratory measurement instruments requiring 52 reliable signal channels. Its 2.54 mm pitch and dual-row format make it a natural fit for any design that must carry multiple digital or analog signals between stacked or side-by-side PCB assemblies.
