What are the key features of TST-110-01-H-D?
- 30 µin gold over 50 µin nickel dual-layer contact finish provides outstanding corrosion resistance and low contact resistance across hundreds of mating cycles
- Shrouded dual-row housing with 20 positions (2×10) on 0.100" (2.54 mm) pitch prevents mis-insertion and protects male contacts during repeated mating
- Compact 1.3" body length with RoHS-compliant (Pb-free) materials suits space-constrained embedded and industrial PCB designs
What is TST-110-01-H-D used for?
The TST-110-01-H-D is a popular choice for embedded system backplanes, development board expansion headers, and industrial control field-wiring interfaces where a reliable 20-pin polarized header on 0.100" pitch is required. The gold contact finish ensures consistent performance in test jigs and field-serviceable modules subject to repeated cable swaps. Its standard 2.54 mm pitch makes it interchangeable with a wide variety of IDC ribbon-cable connectors and discrete socket strips.

Frequently Asked Questions
How does the dual-layer 30 µin gold over 50 µin nickel finish on TST-110-01-H-D extend connector service life?
The 30 µin gold layer provides a noble-metal outer surface that resists oxidation and tarnish, while the 50 µin nickel barrier prevents diffusion of base metal copper into the gold, maintaining low contact resistance even after extensive use. This dual-layer finish supports reliable electrical performance over a typical rated mating cycle count of 30 or more cycles in the -55°C to +125°C operating range.
In a system with a 20-wire ribbon cable, how does the shrouded housing on TST-110-01-H-D reduce assembly errors?
The shroud guides the mating IDC connector into the correct orientation on the 20-position, 0.100" pitch header, physically blocking reversed or offset insertion attempts. This polarization is particularly important in high-volume production environments or field service scenarios where operators must connect ribbon cables quickly and accurately without visual verification of every pin, preventing potential damage to the PCB or connected circuits.
When is TST-110-01-H-D a practical alternative to a 20-pin vertical through-hole connector for an industrial control board?
The TST-110-01-H-D is preferable when the PCB design requires a shrouded, polarized header compatible with standard 20-way IDC ribbon cable on 0.100" pitch in a compact 1.3" body footprint, and when RoHS-compliant, Pb-free materials are mandated by regulation. Its shorter factory lead time of approximately 3 weeks makes it a reliable procurement option compared to custom through-hole alternatives that may require longer lead times or minimum order quantities.
