Key Features
- Gold over Nickel contact finish on both mating and termination surfaces delivers ultra-low contact resistance and exceptional corrosion resistance for high-reliability applications
- 24-way dual-row configuration at 5.08 mm pitch in a 2.3 inch body length accommodates dense multi-signal routing in industrial and computing equipment
- Through-hole vertical (THT) termination provides superior mechanical strength and resistance to vibration compared to surface mount alternatives, ideal for harsh environments
- Lead-free RoHS compliant construction meets global environmental regulations for consumer, industrial, and aerospace market applications
Applications
The TSW-212-11-G-Q is designed for demanding board-to-board and wire-to-board interconnect applications in industrial automation equipment, test and measurement instruments, and embedded computing platforms where 24 signal positions and robust mechanical retention are required. Its gold contact finish and through-hole termination make it well suited for backplane connectors, expansion card slots, and module interfaces that undergo hundreds to thousands of mating cycles over a product's service life. The 5.08 mm pitch also accommodates termination of multi-conductor ribbon cables and discrete wire harnesses in panel-mount control systems.

Frequently Asked Questions
What is the pin pitch and total position count of TSW-212-11-G-Q, and how does it handle high-density routing?
The TSW-212-11-G-Q uses a 5.08 mm pitch in a dual-row, 24-way configuration across a 2.3 inch body length. This larger pitch compared to 2.54 mm headers provides more physical space per contact, making it easier to route heavier gauge wires or accommodate larger terminal crimps in industrial wiring harness applications.
Why does TSW-212-11-G-Q use gold over nickel contact plating, and when does this justify the cost premium?
The gold over nickel finish provides contact resistance typically below 10 milliohms and resists oxidation over thousands of mating cycles, unlike tin-plated contacts that degrade after a few hundred engagements. This cost premium is justified in test fixtures, laboratory instruments, and industrial connectors that undergo daily reconnections and require consistent signal integrity over a service life exceeding 5 years.
Does the through-hole design of TSW-212-11-G-Q offer mechanical advantages over surface mount connectors in vibration environments?
Yes, through-hole termination anchors each of the 24 pins through the PCB substrate, providing pull-out strength several times higher than equivalent SMT pads, typically exceeding 10 N per pin. This makes TSW-212-11-G-Q suitable for industrial machinery, transportation electronics, and ruggedized equipment subjected to continuous vibration levels of 5 g or higher.
What mating connectors or cable assemblies are compatible with TSW-212-11-G-Q for a complete interconnect solution?
The TSW-212-11-G-Q receptacle at 5.08 mm pitch mates with standard 5.08 mm pitch dual-row pin headers such as the SAMTEC TSS or compatible third-party equivalents with male contacts. It also accommodates discrete wire crimp terminations using 26 to 22 AWG conductors, enabling direct connection of harness assemblies up to 24 wires from remote sensors, actuators, or power distribution panels.
