Frequently Asked Questions
How many positions and what pitch does the HTSS-128-01-SS-DV-P-TR provide for cable interconnection?
The HTSS-128-01-SS-DV-P-TR provides 56 positions on a 0.100 inch (2.54 mm) pitch single-row configuration. This allows routing of up to 56 individual signal or power lines through a single polarized connector, suitable for wide bus interfaces such as parallel data, GPIO expanders, or multi-channel sensor arrays in industrial control systems.
Why are stainless steel contacts specified for HTSS-128-01-SS-DV-P-TR in harsh industrial deployments?
Stainless steel contacts on the HTSS-128-01-SS-DV-P-TR provide superior resistance to oxidation, chemical exposure, and fretting corrosion compared to standard brass contacts, maintaining contact resistance below 20 mΩ even after thousands of mating cycles. This is particularly important in industrial environments with humidity above 85% RH or exposure to cleaning solvents and light contaminants.
What temperature range does the HTSS-128-01-SS-DV-P-TR housing withstand during PCB reflow assembly?
The HTSS-128-01-SS-DV-P-TR is a high-temperature connector rated to withstand reflow soldering profiles with peak temperatures up to 260°C, consistent with lead-free solder requirements. Its operating temperature range typically extends from -55°C to 125°C or higher, making it suitable for under-hood automotive, industrial furnace-adjacent, and military avionics applications where standard nylon housings would deform.
What cable assembly types mate with the HTSS-128-01-SS-DV-P-TR and how is mis-mating prevented?
The HTSS-128-01-SS-DV-P-TR mates with standard 0.100 inch pitch IDC ribbon cable assemblies and discrete crimp-style wire connectors. The polarized shroud provides mechanical keying that restricts insertion to a single correct orientation across all 56 positions, preventing reversed connections that could damage adjacent circuitry running at 3.3 V, 5 V, or 12 V logic and power levels.
How does tape-and-reel packaging of HTSS-128-01-SS-DV-P-TR benefit high-volume PCB manufacturing?
The tape-and-reel (TR) suffix on HTSS-128-01-SS-DV-P-TR indicates packaging in continuous carrier tape compatible with standard SMT pick-and-place machines, typically at 500 or 1000 parts per reel. This eliminates manual connector placement for 56-position headers, reducing per-board assembly time by 5 to 15 seconds and enabling consistent placement accuracy within 0.1 mm on high-speed assembly lines.
