Key Features
- 42-position dual-row 2.54 mm pitch layout supports medium-density wire-to-board harness assemblies
- High-temperature shrouded housing rated above 85°C for industrial and thermal-intensive environments
- Surface-mount SS termination style enables automated PCB assembly with precise coplanarity
- Polarized shroud prevents mating cable misalignment across all 42 positions during field installation
Applications
The HTSS-121-01-SS-DV serves as a reliable cable-mate interface on industrial control boards, embedded computing modules, and test fixture backplanes requiring 42 wire-to-board connections at 2.54 mm pitch. Its high-temperature housing withstands sustained operation above 85°C, making it appropriate for motor drive auxiliary boards and power conversion equipment near heat sources. The surface-mount termination streamlines pick-and-place assembly in high-volume production environments.

Frequently Asked Questions
How does the 42-position count of HTSS-121-01-SS-DV compare to the 64-position HTSS-132 for mid-density embedded designs?
The HTSS-121-01-SS-DV provides 42 pins across a dual-row 2.54 mm pitch layout, occupying roughly 66% of the PCB footprint of the 64-position HTSS-132 variant. For designs with 32 to 42 signal or power connections, the 42-position model avoids unused pins and reduces connector cost while maintaining the same high-temperature housing rated above 85°C.
What PCB land pattern does the surface-mount HTSS-121-01-SS-DV require for reliable automated assembly?
The SS surface-mount termination of HTSS-121-01-SS-DV uses standard 2.54 mm grid through-hole-compatible or SMT pads arranged in two rows of 21 pins, with a recommended solder paste stencil aperture matched to the 0.64 mm square pin cross-section. Coplanarity is maintained within 0.1 mm to ensure consistent reflow soldering in high-volume automated assembly lines.
For a motor drive auxiliary board operating at 105°C ambient, how does HTSS-121-01-SS-DV outperform a standard nylon terminal strip?
Standard nylon (PA66) terminal strips are rated to 85°C continuous, which derates to under 75°C in proximity to heat-generating MOSFETs. The HTSS-121-01-SS-DV's high-temperature housing sustains rated performance at 105°C or above, preventing connector creep, pin loosening, and housing distortion that would compromise signal integrity across all 42 positions during prolonged motor operation.
Which cable assembly standards are compatible with the HTSS-121-01-SS-DV for quick field harness replacement?
The HTSS-121-01-SS-DV mates with SAMTEC's HTM or standard 2.54 mm pitch IDC ribbon and discrete wire housings rated for 28 AWG to 22 AWG conductors carrying up to 1 A per pin at 150 V working voltage. This broad compatibility allows field technicians to replace cable harnesses using off-the-shelf assemblies without custom crimping tools or specialty connectors.
