Frequently Asked Questions
How many positions and what pitch does the TST-111-05-L-D header feature?
The TST-111-05-L-D has 22 positions arranged in a dual-row (2x11) configuration with a standard 0.100 inch (2.54 mm) pitch. This widely used pitch ensures compatibility with common ribbon cables, IDC connectors, and through-hole PCB footprints across a broad range of industrial and consumer applications.
What advantage does the shrouded design of the TST-111-05-L-D provide in assembly environments?
The shrouded housing of the TST-111-05-L-D provides mechanical polarization that prevents incorrect cable or mating connector orientation, reducing mis-mating errors in production. The shroud also protects the 22 male pins from bending or contamination during handling and storage, improving assembly yield on PCBs.
In which embedded system applications is the TST-111-05-L-D most commonly specified?
The TST-111-05-L-D is frequently specified in embedded single-board computers, development kits, and industrial I/O modules where a 22-pin dual-row keyed header at 2.54 mm pitch provides GPIO, bus, or power interconnection. Its shrouded through-hole design also suits ruggedized applications requiring headers that withstand mechanical stress from repeated cable mating cycles.
