What are the key features of TST-110-02-H-D?
- 20-position dual-row shrouded PCB header at 0.100" (2.54 mm) pitch with 1.3 inch body length for standard ribbon cable and board-to-board connections
- 30 µin gold over nickel contact finish on square pin contacts ensures low stable contact resistance and extended mating cycle life
- Shrouded body provides mechanical keying and contact protection, preventing mis-insertion of mating connectors in dense multi-connector PCB layouts
What is TST-110-02-H-D used for?
The TST-110-02-H-D is widely used in industrial control panels, embedded computing boards, and test and measurement equipment where standard 0.100" pitch dual-row headers must interface with ribbon cables or mating sockets in high-cycle applications. Its shrouded design protects 20 square pin contacts from accidental damage during cable attachment and enforces correct polarization for fault-free wiring in automated production environments. The gold contact finish supports reliable operation from -55°C to +125°C across industrial and defense-grade electronics.

Frequently Asked Questions
What contact finish does TST-110-02-H-D use, and how does that affect connector reliability over time?
TST-110-02-H-D uses 30 µin (0.76 µm) gold over nickel plating on both mating and termination surfaces. This finish maintains contact resistance below 20 mΩ across hundreds of mating cycles and resists corrosion from humidity and atmospheric contaminants, making it suitable for industrial and defense applications operating from -55°C to +125°C.
How does the shroud on TST-110-02-H-D protect the connector during cable attachment in dense PCB assemblies?
The shroud physically encases the 20 square pin contacts within a 0.365 inch by 1.3 inch body, guiding the mating connector housing and preventing pin damage during insertion. It also provides mechanical polarization keying so a 20-position cable assembly cannot be inserted backwards, reducing wiring errors in dense multi-connector boards found in industrial and embedded computing systems.
For a 20-wire ribbon cable interface on an embedded controller PCB, how does TST-110-02-H-D compare to an unshrouded alternative?
Compared to an unshrouded 20-position dual-row header at 0.100" pitch, TST-110-02-H-D adds a protective shroud that guides the mating ribbon cable IDC connector and prevents lateral pin deflection during repeated insertions. In environments where technicians frequently connect or disconnect 20-wire cables, the shrouded design extends pin life beyond 200 mating cycles while the 30 µin gold contact finish preserves signal integrity throughout the connector's service life.
