What are the key features of TST-115-04-G-D?
- 30-position dual-row 0.100" (2.54 mm) pitch shrouded header with gold-plated mating contacts for low-resistance, high-cycle-life interconnects in precision signal applications
- Shrouded housing with polarization key prevents incorrect cable orientation during assembly and field service, reducing wiring errors in 15-per-row dual-row configurations
- Standard 0.100" grid through-hole footprint ensuring broad compatibility with industry-standard IDC cable assemblies and existing PCB layouts without design modification
What is TST-115-04-G-D used for?
The TST-115-04-G-D is a versatile 30-position dual-row shrouded header used in embedded systems, test fixtures, and industrial equipment requiring reliable 0.100" pitch board-to-cable connectivity. Its gold contact finish makes it appropriate for low-level signal applications in data acquisition and instrumentation where contact resistance must remain stable over repeated mating cycles. The shrouded design simplifies cable assembly in field-serviceable equipment racks and control panels with dual-row IDC ribbon cable harnesses.

Frequently Asked Questions
What contact finish does the TST-115-04-G-D use, and how does this affect connector performance over time?
The TST-115-04-G-D uses a gold (G) contact finish on the mating surfaces, which provides superior corrosion resistance and maintains contact resistance below 30 milliohms over thousands of mating cycles. Gold-plated contacts are especially important in low-voltage signal applications below 5 V where even minor oxide formation on tin contacts can introduce signal integrity issues over the connector's service life.
Which cable assemblies are compatible with the TST-115-04-G-D, and how is it typically wired in a system?
The TST-115-04-G-D mates with standard 2x15 (30-pin) IDC ribbon cable assemblies terminated to 28 AWG or 26 AWG flat ribbon cable on a 0.100" (2.54 mm) pitch. It also accepts discrete-wire housings with individual crimp contacts. In a typical system, it routes 30 signal or mixed-power circuits from a controller PCB to a remote sensor array, I/O panel, or daughtercard, with cable lengths from 100 mm to over 500 mm supported.
When should an engineer choose TST-115-04-G-D over an unshrouded 30-pin header in the same 0.100" pitch?
An engineer should specify the TST-115-04-G-D over an unshrouded header whenever the assembly or field environment increases the risk of mis-mating a 30-pin cable. The shroud mechanically constrains the cable connector, preventing single-row offset errors that can short adjacent pins and damage circuitry. This is especially relevant in high-density panels where 30-pin connectors sit close together and visual differentiation between adjacent headers is difficult during maintenance at 0.100" spacing.
