What are the key features of TST-112-05-L-D?
- 24-position dual-row header with industry-standard 0.100 inch (2.54 mm) pitch for broad connector compatibility
- Polarized shrouded housing prevents incorrect mating orientation and protects signal integrity
- Right-angle low-profile design supports space-efficient PCB assembly in height-constrained enclosures
What is TST-112-05-L-D used for?
The TST-112-05-L-D is suited for embedded systems, industrial control boards, and test-and-measurement equipment where 24-circuit shrouded headers provide secure, polarized wire-to-board connections. Its 0.100 inch pitch aligns with standard ribbon cable assemblies, enabling straightforward integration with IDC connectors and flat cables. Engineers select this header for backplane interconnects, data acquisition modules, and development boards requiring reliable multi-pin signal routing.

Frequently Asked Questions
How does the 0.100 inch pitch of the TST-112-05-L-D compare to finer-pitch alternatives for high-density boards?
The TST-112-05-L-D uses the industry-standard 0.100 inch (2.54 mm) pitch, which provides generous contact spacing compared to 0.050 inch or 1.00 mm pitch alternatives. This standard pitch accommodates a wide range of IDC cable assemblies and mating sockets, simplifying sourcing while still fitting a 24-position dual-row header within approximately 30 mm of PCB width.
What is the maximum current rating per contact for the TST-112-05-L-D, and how does that affect power distribution design?
SAMTEC TST-series headers at 0.100 inch pitch are typically rated at up to 3 A per contact at room temperature. For the 24-position TST-112-05-L-D, designers can distribute power across multiple contacts to handle higher aggregate currents, making the connector suitable for mixed signal-and-power bus connections in industrial I/O boards and embedded computing modules.
When would TST-112-05-L-D be preferred over an unkeyed dual-row header in a manufacturing environment?
The shrouded, polarized housing of the TST-112-05-L-D physically prevents incorrect cable insertion, reducing assembly errors on production lines. In environments where 24-circuit harnesses are hand-assembled, this keyed shroud can eliminate mis-keying damage and the associated rework costs, making it a strong choice for manufacturing settings handling hundreds of 0.100 inch pitch cable assemblies daily.
