What are the key features of TST-115-03-S-D?
- 30-position dual-row shrouded header at industry-standard 0.100 inch (2.54 mm) pitch for broad cable compatibility
- Gold (30 microinch) over nickel (50 microinch) mating contact finish delivering low contact resistance and corrosion protection
- Polarizing shroud prevents incorrect cable insertion, reducing assembly errors in production and field service
What is TST-115-03-S-D used for?
The TST-115-03-S-D shrouded PCB header is widely used in industrial control panels, programmable logic controller (PLC) backplanes, and test-and-measurement instruments requiring reliable ribbon cable or IDC harness connections across 30 dual-row contacts. Its 0.100 inch pitch makes it compatible with a broad range of standard ribbon cable assemblies, and the polarizing shroud ensures correct orientation every time.

Frequently Asked Questions
What contact plating does the TST-115-03-S-D use, and how does this affect long-term connection reliability?
The TST-115-03-S-D uses gold (30 microinch) over nickel (50 microinch) on the mating surface of its phosphor-bronze contacts. This two-layer finish keeps contact resistance below 20 milliohms even after 200 or more mating cycles, resisting oxidation and fretting corrosion in applications where connectors are re-mated during maintenance or field upgrades.
For a PLC backplane requiring 30 signal lines, why is the TST-115-03-S-D a practical header choice?
The TST-115-03-S-D provides 30 contacts in a compact dual-row 0.100 inch pitch layout measuring 1.8 inches in body length. Its polarizing shroud prevents reversed cable insertion, which is critical in PLC backplanes where mis-connection could damage logic circuitry. The tin-over-nickel termination finish ensures reliable soldering to through-hole PCB pads.
How does the TST-115-03-S-D body size compare to other SAMTEC TST series headers with fewer positions?
The TST-115-03-S-D has a body length of 1.8 inches and a breadth and depth each of 0.365 inch. Smaller position-count TST headers in the same series are proportionally shorter in the 0.100 inch pitch row direction. This modular family scaling lets engineers select from 6-position to 50-position variants, all sharing the same shroud height and mounting footprint width.
What cable assembly types mate reliably with the TST-115-03-S-D, and are there sourcing advantages?
The TST-115-03-S-D is compatible with standard 30-position IDC ribbon cable assemblies using 0.100 inch dual-row sockets, which are widely available from multiple manufacturers. Using an industry-standard 2.54 mm pitch also means replacement cables can be sourced from many distributors globally with typical lead times under 2 weeks and unit pricing as low as a few cents per pin for volume orders.
