Key Features
- 24-position dual-row layout at 2.54mm (0.100 inch) pitch provides compact high-density cable-mate connectivity on a 1.35 inch board footprint
- Matte tin (Sn) over nickel (Ni) barrier contact plating delivers low-resistance mating and long-term corrosion protection across temperature cycles
- High-temperature shrouded housing with polarized dual-row design prevents mis-insertion in automated and field-service assembly environments
Applications
The HTSS-112-01-TM-DV is deployed in industrial controller boards, embedded computing modules, and test fixture assemblies where 24 signal or power lines must be brought out to a cable harness in a polarized, vibration-resistant connection. Its high-temperature shrouded body makes it well suited for use inside servo drives, power conversion chassis, and automotive test bench wiring where ambient temperatures can exceed 85°C and connector mis-insertion must be prevented.

Frequently Asked Questions
What are the body dimensions of the HTSS-112-01-TM-DV and how do they constrain PCB layout?
The connector body measures 1.35 inches in length, 0.365 inches in breadth, and 0.4 inches in depth. On a PCB, this occupies a keep-out footprint of approximately 34.3mm x 9.3mm, and the 0.4 inch depth means the connector body stands about 10mm above the board surface, so nearby tall components must maintain at least 12mm clearance to avoid mechanical interference during cable mating.
What contact plating is used on the HTSS-112-01-TM-DV and how does it benefit long-service-life industrial applications?
Both mating and termination surfaces use matte tin (Sn) over a nickel (Ni) barrier layer. The nickel barrier prevents tin whisker diffusion and intermetallic growth between tin and the base copper alloy over hundreds of thermal cycles, keeping contact resistance stable. Matte tin finishes also offer better resistance to fretting corrosion under vibration than bright tin, which is important for connectors in servo controller or motor driver enclosures.
How does the 24-position dual-row layout compare to a single-row 24-pin connector for the same application?
A dual-row 24-position connector at 0.100 inch pitch has 12 contacts per row, occupying only half the linear board length of a single-row 24-pin connector at the same pitch. For a PCB edge or internal routing channel with limited space, the dual-row HTSS-112-01-TM-DV fits within 1.35 inches versus roughly 2.5 inches for a single-row alternative, freeing significant PCB edge length for other connectors or traces.
Can the HTSS-112-01-TM-DV be used in designs that require high ambient temperature above 85°C?
Yes. The HTSS series is specifically rated for high-temperature operation, with housing materials selected to maintain dimensional stability and contact retention force at temperatures typically reaching 105°C or above continuous duty. This makes it suitable for use inside closed enclosures near power stages, industrial servo drives, and embedded computing modules where airflow is restricted and internal temperatures rise well above the 85°C rating of standard board connectors.
