Key Features
- 42-position dual-row male square-pin contacts on 0.100-inch pitch for high-density PCB-to-cable signal routing
- High-temperature rated shroud body (2.25 x 0.365 x 0.4 inches) prevents mis-mating and protects contacts in harsh thermal environments
- Board-mount rectangular contact pattern enables direct PCB soldering with secure mechanical retention for vibration-prone industrial installations
Applications
The HTSS-121-01-S-DV is well suited for industrial automation panels, robotics control boards, and embedded computing backplanes where 42 signals must be reliably routed from a PCB to a ribbon cable assembly in thermally demanding enclosures. Its shrouded dual-row format prevents incorrect cable insertion during field maintenance, making it a dependable choice for test and measurement equipment and medical device interconnect systems.

Frequently Asked Questions
How many signal positions and what pitch does the HTSS-121-01-S-DV provide?
The HTSS-121-01-S-DV offers 42 positions arranged in a dual-row layout on a standard 0.100-inch (2.54 mm) pitch. Each row carries 21 male square-pin contacts, providing a compact 2.25-inch body length for routing up to 42 signals in a single PCB-to-cable interface.
Why does the shrouded housing of the HTSS-121-01-S-DV matter in field-serviceable equipment?
The shroud physically guides the mating cable connector into the correct 42-pin alignment, preventing reversed insertion errors that could damage 3.3 V or 5 V logic on the target board. In field environments with frequent connect/disconnect cycles, the shroud also shields the male square pins from mechanical damage and contamination, extending service life.
What are the physical dimensions of the HTSS-121-01-S-DV and how do they affect PCB layout?
The HTSS-121-01-S-DV body measures 2.25 inches long, 0.365 inches wide, and 0.4 inches deep. This footprint requires a PCB keep-out zone of approximately 57 mm x 10 mm, which fits most standard mid-size PCB edge-connector placements in industrial control and data acquisition boards.
When is the HTSS-121-01-S-DV a better fit than a non-shrouded 42-pin strip for high-volume production?
For high-volume assembly where ribbon cables are installed by machine or in poor-lighting conditions, the shroud on the HTSS-121-01-S-DV reduces mis-mating defect rates to near zero. The rectangular contact pattern with 0.100-inch spacing also simplifies automated cable assembly tooling, saving rework costs on 42-pin harnesses at scale.
