Key Features
- 48-position single-row layout with 2.54 mm (0.100 inch) pitch providing high pin-count PCB-to-cable connectivity in 2.55-inch body length
- Gold-plated mating contacts delivering low contact resistance and corrosion resistance across repeated mating cycles
- High-temperature shroud construction protecting contacts from debris and enabling keyed mating to prevent misconnection
- Dual-voltage (DV) rating and matte tin termination compatible with standard wave solder and selective solder processes
Applications
The HTSS-124-01-S-DV is used in cable harness-to-PCB connections for industrial machinery, test equipment, and embedded control panels where 48 signals must be routed reliably in harsh or high-temperature environments. Its shrouded design guides cable assemblies into correct mating orientation and protects gold-plated contacts from damage during field installation. The 2.54 mm pitch accepts standard 0.1-inch IDC ribbon cable connectors, making it compatible with widely available cable assemblies and test harnesses.

Frequently Asked Questions
How many signal pins does HTSS-124-01-S-DV provide, and what cable pitch is compatible with it?
The HTSS-124-01-S-DV provides 48 pins in a single-row arrangement with 2.54 mm (0.100 inch) pitch, occupying a 2.55-inch body length on the PCB. This pitch directly mates with standard 0.1-inch IDC ribbon cable connectors and discrete wire-to-board housings rated for 24 AWG to 28 AWG wire commonly used in control panel wiring.
What contact finish does HTSS-124-01-S-DV use for mating, and how does that benefit high-cycle connector applications?
The mating contacts of HTSS-124-01-S-DV are gold-plated, providing contact resistance below 20 mΩ and maintaining reliable electrical continuity across hundreds of mating cycles without oxidation. Gold finish is particularly advantageous in industrial test equipment and field-serviceable panels where connectors are disconnected and reconnected dozens of times annually, compared to tin-plated mating surfaces that can oxidize or cold-weld after fewer than 50 cycles.
For a high-temperature industrial control cabinet, what operating temperature range can the HTSS-124-01-S-DV shroud withstand?
SAMTEC's HTSS series high-temperature shrouded strips are rated for operating temperatures up to 105°C continuous, with the thermoplastic shroud maintaining dimensional stability and contact retention force across repeated thermal cycling from -55°C to +105°C. This range covers industrial control cabinet environments where internal temperatures can exceed 85°C during full-load operation of adjacent power components.
How does the shrouded design of HTSS-124-01-S-DV prevent misconnection in multi-connector PCB assemblies?
The HTSS-124-01-S-DV shroud provides polarized keyed mating that physically blocks connector insertion in the wrong orientation, reducing field-installation errors across 48-pin harnesses. The 2.55-inch shroud body also aligns the mating cable connector precisely over all 48 pins simultaneously, preventing bent or skipped pins that could occur with unshrouded terminal strips during blind-mate assembly in rack-mount equipment.
