Key Features
- Gold-plated mating contacts on phosphor bronze provide stable contact resistance below 20 milliohms over 500 mating cycles in high-humidity environments
- High-temperature shroud withstands up to 125°C continuous operation, meeting requirements for automotive wiring harness and industrial motor drive applications
- Tin-over-nickel (Sn/Ni) solder termination with nickel barrier prevents tin-whisker growth and improves solder joint reliability on the PCB side
Applications
HTSS-125-01-L-DV is designed for demanding cable-to-board interconnect applications in automotive wiring harnesses, industrial automation panels, and power conversion equipment where both high temperature and reliable contact performance are required. The 50-position shrouded design guides the mating harness connector into correct alignment, reducing mismate risk during vehicle assembly or field service. Gold-plated contacts ensure repeatable low-resistance connections on signal and power lines throughout the connector's rated service life.

Frequently Asked Questions
What contact material and plating does HTSS-125-01-L-DV use, and how does this affect mating life?
HTSS-125-01-L-DV uses phosphor bronze contacts with a gold-plated mating surface and tin-over-nickel termination finish. The gold plating on the mating interface maintains contact resistance below 20 milliohms for a rated 500 or more mating cycles, while the nickel barrier under the tin solder termination prevents interdiffusion and supports long-term solder joint reliability on the PCB.
Can HTSS-125-01-L-DV withstand the thermal environment inside an automotive ECU enclosure?
Yes, HTSS-125-01-L-DV is rated for continuous operation at up to 125°C, which covers the thermal environment of automotive ECU enclosures and under-dash wiring harness applications. The high-temperature shroud material maintains dimensional stability at 125°C, ensuring the mating polarization key retains its geometry and prevents mis-mating even after prolonged thermal cycling.
How does the shrouded design of HTSS-125-01-L-DV reduce assembly errors compared to an open-pin strip header?
The shrouded housing on HTSS-125-01-L-DV physically encases and polarizes the 50-pin contact array with a keyed cavity that accepts only the correctly oriented mating connector. An open-pin header has no such guidance, so a 50-pin harness connector can be offset by 1 or more pins or inserted at 180 degrees without obvious resistance, causing hard-to-diagnose circuit failures. The shroud eliminates this mismate mode and protects the gold-plated contacts from accidental mechanical damage during harness routing.
