Key Features
- 10-pin dual-row right-angle PTH box header with gold (10 µin) over nickel (50 µin) mating contact finish for reliable low-resistance connections
- Matte tin over nickel barrier termination contacts for robust through-hole soldering and long-term reliability
- Shrouded housing prevents mismating and provides mechanical protection, with a 0.8 inch body length and 1-week factory lead time
Applications
The TST-105-04-L-D-RA is suited for board-to-board and wire-to-board interconnect in industrial control systems, embedded computing modules, and test equipment where a right-angle orientation conserves vertical clearance. Its shrouded design prevents misalignment during mating, making it reliable in automated assembly and high-vibration environments. The 10-pin dual-row layout supports dense signal routing across backplanes, daughtercards, and development boards.

Frequently Asked Questions
What are the contact finish specifications for TST-105-04-L-D-RA mating contacts?
The TST-105-04-L-D-RA uses gold (10 µin) plated over nickel (50 µin) on mating contacts, providing low contact resistance and excellent corrosion resistance over thousands of mating cycles in 10-pin dual-row configurations.
Which PCB orientations and panel configurations does TST-105-04-L-D-RA support for board-to-board connections?
The TST-105-04-L-D-RA is a right-angle PTH box header with a 0.8 inch body length, 0.365 inch breadth, and 0.498 inch depth, enabling horizontal board-to-board connections where vertical space is limited to less than 0.5 inch above the PCB surface.
How does the shrouded housing on TST-105-04-L-D-RA improve reliability in industrial environments?
The shrouded housing of the TST-105-04-L-D-RA physically guides mating connectors into the correct 10-pin, dual-row alignment, preventing cross-mating errors and providing mechanical protection against vibration and shock in industrial control, test, and embedded computing applications.
