What are the key features of TST-111-02-G-D?
- Gold (10 micro-inch) over nickel mating contact finish for low-resistance, corrosion-resistant interconnects
- 22-position dual-row shrouded layout at 0.100 inch (2.54 mm) pitch with polarized housing for keyed mating
- Square pin-socket contact geometry providing four-point contact for enhanced mating reliability in vibration-prone environments
What is TST-111-02-G-D used for?
The TST-111-02-G-D is designed for through-hole PCB header applications in industrial control systems, test and measurement equipment, and embedded computing boards requiring a 22-position shrouded dual-row connector. The shroud provides mechanical keying to prevent misalignment during mating with ribbon cable or IDC receptacles. Gold-over-nickel contact finishes ensure long-term signal reliability across multiple connection cycles.

Frequently Asked Questions
What contact finish is used on the TST-111-02-G-D and how does it affect performance?
The TST-111-02-G-D uses gold (10 micro-inches) over nickel on the mating contacts and gold with nickel barrier on the termination contacts. This gold finish provides excellent corrosion resistance, low contact resistance, and reliable signal performance across thousands of mate and unmate cycles in industrial environments.
Which ribbon cable or IDC connector configurations mate reliably with the TST-111-02-G-D header?
The TST-111-02-G-D 0.100 inch (2.54 mm) pitch dual-row shrouded header mates with standard 22-position IDC ribbon cable receptacles and dual-row socket assemblies. The polarized shroud enforces correct orientation, preventing pin misalignment during cable attachment on industrial PCBs with 22 signals routed via flat ribbon cable.
How do the physical dimensions of the TST-111-02-G-D constrain PCB layout and component clearance?
The connector body measures 1.4 inches in length, 0.365 inches in depth, and 0.365 inches in breadth. This relatively tall profile requires adequate component clearance on both sides of the PCB, particularly when mounting in enclosures where header height above the board surface is limited to under 0.365 inches.
When is the TST-111-02-G-D preferred over an unkeyed header for 22-position through-hole connectors?
The shrouded design of the TST-111-02-G-D is preferred whenever incorrect mating orientation would damage components or signals on 22 active pins. Industrial control and test equipment benefit from the shroud keying because operators connecting cables in the field are physically prevented from inserting connectors in a reversed position, reducing risk of damage from miswiring.
