What are the key features of TST-111-02-T-D?
- 22-pin dual-row shrouded PCB header at 0.100-inch (2.54 mm) pitch with rectangular contact pattern for reliable polarized board-to-cable or board-to-board connections
- Tin (200 µin) over Nickel contact finish on male square-pin contacts provides robust solderability and corrosion resistance for long-term signal integrity
- Protective shroud prevents mis-mating and shields contact pins from mechanical damage during cable assembly and field maintenance operations
What is TST-111-02-T-D used for?
The TST-111-02-T-D shrouded PCB header is commonly used in industrial control systems, embedded computing boards, and test equipment where polarized, keyed 22-pin connectors prevent reverse insertion during cable assembly. Its 0.100-inch pitch and tin-plated contacts support standard ribbon cable and IDC connector mating across a wide range of signal and low-voltage power applications. The robust shroud design makes it suitable for field-installable backplane and daughtercard interconnects where accidental mis-mating must be prevented.

Frequently Asked Questions
What contact finish does the TST-111-02-T-D use, and how does it compare to gold-plated alternatives for industrial use?
The TST-111-02-T-D uses tin (200 µin) over nickel contact finish, which provides good solderability and adequate corrosion resistance for most industrial environments at a lower cost than gold plating. For applications requiring more than 25 mating cycles or exposure to harsh atmospheres, gold over nickel contacts from SAMTEC's TSM series may be preferred, but for typical cable-assembly use the tin finish performs reliably.
How does the shroud on the TST-111-02-T-D help prevent wiring errors in multi-connector board assemblies?
The protective shroud around the 22-pin dual-row male contacts physically blocks incorrect orientation of mating IDC or ribbon cable connectors, enforcing a single valid insertion direction. In assemblies with multiple adjacent headers, the shroud also provides a keying reference that reduces field wiring errors, particularly important in industrial control boards where a mis-wired connector could damage a 3.3 V or 5 V logic circuit.
What body dimensions should a PCB designer use when laying out the TST-111-02-T-D footprint?
The TST-111-02-T-D has a body length of 1.4 inches, body breadth of 0.365 inch, and body depth of 0.365 inch, providing the outer envelope for PCB keepout and connector housing clearance. At 0.100-inch (2.54 mm) pitch with 11 positions per row, the pin field spans approximately 1.0 inch row-to-row, and designers should add at least 2 mm clearance around the shroud for cable strain relief.
For a cost-sensitive production build, when is the TST-111-02-T-D a practical choice over fine-pitch alternatives?
The TST-111-02-T-D's standard 0.100-inch (2.54 mm) pitch and tin-plated contacts make it one of the most cost-effective 22-pin shrouded headers available, with pricing typically well below fine-pitch gold-contact alternatives. It mates directly with standard 22-pin IDC ribbon cable assemblies, eliminating the need for custom cable tooling, and SAMTEC's Tiger Buy stocking program supports rapid procurement with as little as 1-week lead time for volume orders.
