Frequently Asked Questions
What contact finish and pin count does the TST-112-03-S-D provide, and why does that matter for reliability?
The TST-112-03-S-D features 24 male pins arranged in 2 rows of 12 at 0.100" (2.54 mm) pitch, with a 30 micro-inch gold over 50 micro-inch nickel contact finish on the mating surface. This gold finish minimizes contact resistance and resists oxidation, making it suitable for applications requiring thousands of mating cycles without degradation, such as test fixtures and industrial board connectors.
How does the shrouded housing of the TST-112-03-S-D improve field assembly versus unshrouded headers?
The TST-112-03-S-D's shroud aligns mating cable connectors and prevents off-axis insertion, reducing the risk of bent pins or mis-mated connections during board assembly or field replacement. The 1.5" body length with 0.365" depth provides a defined envelope that matches standard 2x12 IDC cable connector housings, ensuring correct polarized engagement every time without visual confirmation in cramped enclosures.
What types of mating cable assemblies are compatible with the TST-112-03-S-D shrouded header?
The TST-112-03-S-D mates with standard 24-pin IDC ribbon cable assemblies and discrete-wire housings on a 0.100" (2.54 mm) grid, including widely available 2x12 IDC connectors terminated to 28 AWG or 26 AWG flat ribbon cable. These assemblies are available from multiple suppliers, simplifying sourcing for production and field service in applications where replacement cables must be easy to procure globally.
