Frequently Asked Questions
What is the contact pitch and row configuration of the TST-112-03-H-D?
The TST-112-03-H-D uses a 0.100" (2.54 mm) pitch in a dual-row configuration providing 24 positions total, 12 per row, making it compatible with standard 0.100" socket housings widely used in embedded and industrial designs.
Which board-to-board applications benefit most from the TST-112-03-H-D shrouded design?
The shrouded housing on the TST-112-03-H-D prevents pin misalignment during mating, making it ideal for backplane assemblies, industrial control cards, and test fixtures where blind-mating with 24-pin dual-row sockets at 0.100" pitch must be reliable and repeatable.
What contact finish does the TST-112-03-H-D use and why does it matter for signal integrity?
The TST-112-03-H-D uses 30 µin gold over nickel contact finish. Gold plating at 30 µin provides low and stable contact resistance across thousands of mating cycles, supporting signal integrity in systems operating up to the connector's rated electrical limits, which is critical for data acquisition and control applications.
