What are the key features of TST-111-05-T-D?
- 22-pin dual-row shrouded PCB header at 0.100-inch (2.54 mm) standard pitch compatible with common IDC and ribbon cable connectors for broad ecosystem support
- Protective shroud enforces single-orientation mating, preventing reverse insertion errors in multi-connector industrial board assemblies and reducing field wiring mistakes
- Tin contact finish on male square-pin contacts provides excellent solderability for wave or selective solder processes at temperatures up to 260°C without contact degradation
What is TST-111-05-T-D used for?
The TST-111-05-T-D shrouded PCB header is used in industrial automation panels, embedded single-board computers, and test instrumentation where a keyed 22-pin connector prevents incorrect cable attachment during system assembly or field maintenance. Its standard 0.100-inch pitch allows mating with a wide range of commercial IDC ribbon cable assemblies supporting signal and low-voltage power routing. The through-hole termination style provides mechanically robust attachment suitable for high-vibration environments such as motor control enclosures and ruggedized field equipment.

Frequently Asked Questions
How many signal positions does the TST-111-05-T-D accommodate, and at what pitch are they arranged?
The TST-111-05-T-D provides 22 pins arranged in a dual-row format at 0.100-inch (2.54 mm) pitch, with 11 contacts per row. This standard pitch directly mates with common 22-pin IDC ribbon cable assemblies and is compatible with a broad range of commercial cable connectors, making it a versatile choice for embedded system I/O headers and backplane signal routing.
In a factory automation system with multiple identical headers, how does the TST-111-05-T-D's shroud reduce wiring errors during commissioning?
The protective shroud physically constrains the mating cable connector to a single valid insertion orientation, preventing reverse or off-center insertion that could short 5 V power pins to signal lines and damage downstream logic. In a panel with 4 or more adjacent headers, the shroud also creates a distinct visual and tactile reference that speeds cable installation during commissioning and reduces troubleshooting time caused by wiring errors.
What is the difference between the TST-111-05-T-D and TST-111-02-T-D, and when would a designer choose one over the other?
Both parts are 22-pin dual-row shrouded headers at 0.100-inch pitch with tin contact finish, but the number suffix (05 vs 02) indicates a different body or termination variant within SAMTEC's TST series, such as post length or board mounting style. A designer would select the -05 variant when the PCB stack height or standoff requirements differ from the -02 configuration, for example when needing a longer 5 mm pin above board for a taller mating cable housing.
For a cost-sensitive industrial control board production run, what makes the TST-111-05-T-D a practical procurement choice?
The TST-111-05-T-D's standard 0.100-inch pitch and tin contact finish make it one of the most economical 22-pin shrouded headers available, with stocking typically supported through SAMTEC's Tiger Buy program offering 1-week lead times. It mates with off-the-shelf IDC cable assemblies eliminating custom tooling cost, and worldwide distributor availability ensures supply chain resilience for production runs in the hundreds to thousands of units.
