Applications
HTSS-128-01-TM-DV is designed for high-temperature PCB-to-cable interconnection in industrial automation, automotive electronics, and embedded computing systems where standard connectors would fail under thermal stress. Its 56-position shrouded configuration supports high-density signal routing between PCBs and cable assemblies in motor controllers, power inverters, and test equipment operating in elevated ambient temperatures. The polarizing shroud and dual-row layout also make it ideal for backplane and daughter-card interconnects where reliable mating under mechanical vibration is essential.

Frequently Asked Questions
How many positions and what pitch does HTSS-128-01-TM-DV provide, and what cable connector does it mate with?
HTSS-128-01-TM-DV offers 56 positions arranged in a dual-row layout on a 2.54 mm (0.1 inch) pitch, mating with standard cable-side HTSS-series connectors from SAMTEC. This configuration supports up to 56 independent signal or power contacts, making it suited for high-density PCB-to-cable wiring in industrial control systems, test equipment, and embedded computing boards.
What thermal performance advantages does HTSS-128-01-TM-DV offer over standard plastic connectors in automotive or industrial designs?
HTSS-128-01-TM-DV uses high-temperature rated housing materials that can withstand elevated ambient temperatures exceeding 105°C, unlike standard connectors that may deform or lose retention force above 85°C. This makes it a reliable choice for automotive under-hood electronics, motor drive control boards, and industrial automation panels where connector integrity at sustained high temperatures is critical.
How does the shroud on HTSS-128-01-TM-DV improve assembly reliability in high-volume manufacturing?
The polarizing shroud on HTSS-128-01-TM-DV physically prevents reversed or offset cable connector insertion, reducing assembly errors in high-volume manufacturing environments. For a 56-position, 2.54 mm pitch connector with multiple row alignments, accidental mis-mating could damage all 56 contacts or create intermittent faults; the shroud eliminates this risk and speeds up cable harness assembly on production lines.
In which dense multi-signal routing scenarios does HTSS-128-01-TM-DV outperform single-row headers of the same pitch?
HTSS-128-01-TM-DV's dual-row, 56-position configuration achieves the same contact density as a single-row 56-pin header but in roughly half the PCB board-edge length at 2.54 mm pitch, saving approximately 70 mm of board space. This compact footprint is critical in backplane interfaces, daughter-card interconnects, and high-density cable harness assemblies where board real estate is limited and many simultaneous signals must cross the PCB-to-cable boundary.
