What are the key features of TST-109-02-H-D?
- 18-position dual-row shrouded header on 0.100 inch (2.54 mm) pitch with polarizing key for fool-proof cable assembly
- Gold (30 microinch) over nickel contact finish ensures low contact resistance and corrosion resistance across 500+ mating cycles
- Rectangular square-pin contact style provides reliable mechanical engagement with standard 0.100 inch pitch female socket connectors
What is TST-109-02-H-D used for?
The TST-109-02-H-D is widely used in prototyping boards, industrial control modules, and embedded development platforms requiring reliable 18-signal board-to-cable or board-to-board interconnects on the industry-standard 0.100 inch pitch grid. The shroud protects contacts during mating and acts as a polarization key that prevents reversed insertion in automated test equipment and field-wired systems. Its gold-plated contacts maintain consistent electrical performance in environments subject to mild vibration and humidity, such as factory automation panels and benchtop instrumentation.

Frequently Asked Questions
What contact finish does the TST-109-02-H-D use, and how many mating cycles does it support?
The TST-109-02-H-D uses a 30 microinch gold over nickel contact finish, which provides low and stable contact resistance across a rated minimum of 500 mating cycles. This finish also resists oxidation and mild corrosion in industrial and laboratory environments where the connector may be exposed to humidity or airborne contaminants.
How does the polarizing shroud on the TST-109-02-H-D reduce wiring errors in field-installed cable assemblies?
The protective shroud around the 18 square-pin contacts of the TST-109-02-H-D incorporates a keying feature that allows the mating female connector to be inserted only in the correct orientation on the 0.100 inch pitch grid. This prevents reversed insertion that could damage components or cause signal cross-connection in embedded control boards, test equipment, or industrial wiring harnesses.
When should a designer choose TST-109-02-H-D over an unshrouded 0.100 inch pin header of the same 18-position count?
TST-109-02-H-D is preferred over unshrouded alternatives when the connector will be mated or unmated frequently in low-visibility conditions such as inside enclosures, or when a reversal error could damage circuit components powered at 5 V or higher. The shroud adds approximately 0.365 inch to both body breadth and depth, but the polarization protection and contact retention it provides justify that additional board area in safety-critical or field-service applications.
