Frequently Asked Questions
How many positions and rows does the TST-112-02-L-D provide, and what is its pitch?
The TST-112-02-L-D is a 24-position dual-row shrouded header with a 0.100" (2.54 mm) pitch. Its body measures 1.5" in length, making it compatible with standard 2.54 mm pitch cable assemblies and mating socket connectors commonly used in industrial and embedded electronics.
What contact material and finish does the TST-112-02-L-D use for reliable mating performance?
The TST-112-02-L-D uses phosphor bronze contacts with gold (10 µin) over nickel (50 µin) mating finish and tin (Sn) over nickel termination finish. This combination provides low contact resistance, excellent spring characteristics, and corrosion resistance suitable for hundreds of mating cycles.
In what industrial or embedded applications is the TST-112-02-L-D typically deployed?
The TST-112-02-L-D suits PCB-to-PCB and PCB-to-ribbon-cable connections in automation controllers, test equipment, single-board computers, and data acquisition systems. The shrouded housing with 0.100" pitch accommodates standard IDC cable assemblies, enabling fast and error-free 24-pin interconnects in field-serviceable equipment.
Can the TST-112-02-L-D be substituted with a non-shrouded header, and what is the key difference?
A non-shrouded 24-position dual-row header at 0.100" pitch can fit the same PCB footprint, but the TST-112-02-L-D shroud provides mechanical polarization that prevents 180-degree mis-mating. For applications where incorrect insertion could damage components operating at 3.3 V, 5 V, or higher supply rails, the shrouded version adds important protection.
