Frequently Asked Questions
How many positions and what pitch does the TSM-126-03-S-DH-A-K-TR offer?
The TSM-126-03-S-DH-A-K-TR features 52 positions arranged in a dual-row configuration with a .100 inch (2.54 mm) pitch, providing 26 positions per row. This layout is suitable for parallel data buses or mixed power and signal connections requiring high pin counts in a compact SMT form factor.
What does the shrouded housing (DH) designation mean for the TSM-126-03-S-DH-A-K-TR?
The DH suffix indicates a dual-row shrouded housing that surrounds the contact array, providing mechanical keying to prevent incorrect connector orientation during mating. This shroud also offers physical protection for the 52 contacts against accidental damage in high-density PCB environments with multiple adjacent connectors.
Can the TSM-126-03-S-DH-A-K-TR be used in high-volume automated assembly lines?
Yes, the -TR suffix designates tape-and-reel packaging, which is fully compatible with standard automated pick-and-place assembly equipment. This packaging format reduces handling time and placement errors when assembling thousands of units, making it cost-effective for production volumes requiring precise component placement of all 52 positions.
What are typical PCB applications for a 52-position dual-row SMT terminal strip like the TSM-126-03-S-DH-A-K-TR?
This connector is commonly used in server backplanes, industrial control modules, and FPGA development boards that need high-density interconnects with 52 or more signal and power lines. It is also found in telecommunications line cards and embedded computing platforms where board-to-board mating at 2.54 mm pitch is required within constrained PCB real estate.
