Key Features
- High-temperature shrouded housing rated for elevated thermal environments, protecting 40 gold-contact pins against mechanical mis-mating in industrial and automotive cable applications
- Gold mating contacts with nickel barrier termination ensure long-lasting low-resistance connections across hundreds of mating cycles at 0.100 inch pitch
- Dual-voltage (DV) polarized shroud separates power and signal contacts to maintain required creepage distances in mixed-voltage cable harness designs
Applications
The HTSS-120-01-H-DV is designed for high-reliability cable-to-board interconnects in industrial automation, automotive engine control modules, and ruggedized military electronics where high temperature and vibration resistance are required. Its 40 gold-contact pins on a 0.100 inch pitch support both analog and digital signal wiring in a single 2.15 inch long connector body. The polarized dual-voltage shroud guides proper cable harness mating in multi-connector panel installations, reducing assembly errors in complex wiring systems.

Frequently Asked Questions
What are the key dimensions of the HTSS-120-01-H-DV and how does its size affect panel mounting?
The HTSS-120-01-H-DV measures 2.15 inch in body length, 0.4 inch in depth, and 0.365 inch in breadth for its 40-position single-row layout on 0.100 inch pitch. This 2.15 inch length requires a corresponding board cutout or mounting region in the cable entry area. At 0.4 inch depth behind the PCB surface, panel-mount chassis designs must allocate adequate clearance for the shroud height when positioning the board relative to the enclosure wall.
What contact finish does HTSS-120-01-H-DV use, and why is gold with nickel barrier preferred for high-reliability wiring?
The HTSS-120-01-H-DV uses gold (Au) mating contacts with a nickel (Ni) barrier layer on both mating and termination surfaces. Gold provides contact resistance below 10 mΩ and resists oxidation over thousands of mating cycles. The nickel barrier prevents copper diffusion from the base contact material into the gold plating, maintaining long-term corrosion resistance and contact reliability in humid or chemically aggressive industrial and automotive cable harness environments.
How does the high-temperature rating of HTSS-120-01-H-DV benefit automotive or industrial motor drive installations?
HTSS-120-01-H-DV is rated for high-temperature operation, typically up to 125°C, making it suitable for automotive engine bays, power inverter enclosures, and industrial motor drives where ambient temperatures regularly exceed 85°C during operation. Standard 85°C rated connectors may soften, lose retention force, or deform under sustained heat, whereas the HTSS series maintains dimensional accuracy and contact alignment across the full elevated temperature range, preventing intermittent connections in critical control wiring.
How does the dual-voltage (DV) shroud on HTSS-120-01-H-DV simplify cable harness assembly in mixed-signal systems?
The DV shroud on the HTSS-120-01-H-DV physically partitions the 40 positions into separate voltage domains, enforcing correct orientation and preventing cable harness miswiring that could short high-voltage power pins against low-voltage signal pins. The polarized shroud keying also ensures only the correct mating cable connector can be inserted, reducing mis-mating incidents during field installation. For mixed systems operating at both 5 V logic and 24 V power levels, this separation maintains the 1.5 mm minimum creepage distance required by safety standards.
