Key Features
- 48-position dual-row (DV) layout at 0.100 inch (2.54 mm) pitch with body length of 2.55 inch for high-density cable harness connections
- Gold-plated mating contacts ensuring low and stable contact resistance across thousands of mating cycles
- Matte tin termination on PCB tails for reliable wave or hand soldering to standard through-hole footprints
- Shrouded rectangular polarized housing preventing mis-mating of 48-pin cable connectors
- High-temperature rated housing maintaining dimensional stability in thermally demanding industrial environments
Applications
The HTSS-124-01-L-DV is widely used in industrial automation panels, defense sub-assemblies, and test-and-measurement equipment requiring a 48-pin cable-to-board connection at 0.100 inch pitch with high-temperature tolerance. Its gold mating contacts and shrouded polarized design make it suitable for frequent connect/disconnect scenarios in field-serviceable motor control units and embedded computer backplanes. The 2.55 inch body length is also common in data acquisition systems and communication equipment where multiple cable harnesses terminate on a single PCB.

Frequently Asked Questions
What contact finish does the HTSS-124-01-L-DV use on the mating surface and why is gold chosen?
The HTSS-124-01-L-DV uses gold-plated mating contacts and matte tin on the PCB termination tails. Gold is selected for the mating surface because it resists oxidation and provides consistent low contact resistance on all 48 pins across repeated mating cycles, which is critical in applications where the cable connector is frequently disconnected for maintenance or equipment reconfiguration in industrial and defense systems.
What are the body dimensions of the HTSS-124-01-L-DV and how does that affect PCB layout?
The HTSS-124-01-L-DV measures 2.55 inches in body length, 0.4 inches in depth, and 0.365 inches in breadth. Designers need to reserve a 2.55 x 0.4 inch keep-out area on the PCB along with clearance for the mating cable connector. The dual-row 48-position layout at 0.100 inch pitch enables this footprint to accommodate 48 contacts in a relatively compact rectangular envelope suitable for edge-of-board placement in industrial control modules.
How does the shrouded design on the HTSS-124-01-L-DV protect the 48-pin interface in field-service scenarios?
The polarized shroud surrounding all 48 contacts on the HTSS-124-01-L-DV prevents technicians from inserting the mating cable connector in the wrong orientation during field servicing, eliminating the risk of reversing polarity or shifting the 0.100 inch pitch alignment by one position. The shroud also physically protects the gold-plated male pins from accidental bending or contamination when the cable is disconnected during maintenance of industrial machinery or defense electronics.
For a 48-pin power and signal harness in a motor controller, when is the HTSS-124-01-L-DV preferred over a screw terminal block?
The HTSS-124-01-L-DV is preferred over screw terminal blocks when the design requires a quick-disconnect cable harness with 48 connections at 0.100 inch pitch that can be assembled in the factory and plugged in during installation. Screw terminals at the same pin count would occupy significantly more board space than the 2.55 inch body of the HTSS-124-01-L-DV, and they require individual wire termination at the installation site. The shrouded header with gold contacts also ensures a more reliable low-resistance connection than screw clamp interfaces in vibrating motor-drive environments.
