Key Features
- 24-way dual-row layout on 5.08 mm (0.200") pitch provides robust contact spacing for power and signal interconnect in test equipment and industrial applications
- Gold-over-nickel contact finish on both mating and termination surfaces ensures low contact resistance and long-term corrosion resistance across many mating cycles
- Through-hole vertical (THT) mounting with receptacle-style body provides secure mechanical anchoring to PCB for applications subject to vibration or repeated connector mating
Applications
The TSW-212-12-G-Q is used in test and measurement equipment, industrial control panels, and development boards where a robust 24-position board connector with reliable gold contact finish is required. Its 5.08 mm pitch and through-hole mounting provide strong mechanical stability in environments subject to vibration or thermal cycling. The dual-row male header configuration accommodates high current and signal pin assignments in backplane and module-to-module interconnect designs.

Frequently Asked Questions
What contact pitch and number of ways does the TSW-212-12-G-Q connector provide?
The TSW-212-12-G-Q is a 24-way connector arranged in a dual-row layout on a 5.08 mm (0.200") pitch. The wider 5.08 mm spacing compared to 2.54 mm headers provides greater creepage distance between contacts, supporting higher voltage separation and easier manual soldering in test equipment and industrial PCB assemblies.
How does the gold-over-nickel contact finish of TSW-212-12-G-Q affect connector longevity?
The gold-over-nickel contact finish on both the mating and termination surfaces of the TSW-212-12-G-Q provides excellent resistance to oxidation and corrosion, maintaining low contact resistance across hundreds of mating cycles. Gold-plated contacts are preferred in signal-critical and low-current applications where oxide buildup on base-metal contacts could increase insertion loss or cause intermittent connections over time.
Is TSW-212-12-G-Q suitable for environments with mechanical vibration?
Yes, the through-hole vertical (THT) mounting of the TSW-212-12-G-Q provides strong solder joint anchoring to the PCB, making it more resistant to mechanical vibration and connector extraction forces than SMT alternatives. The body dimensions of approximately 2.3 inches length and receptacle-style shell add physical robustness for use in industrial control panels and test fixtures subject to repeated handling.
What mating connectors are compatible with the TSW-212-12-G-Q header?
The TSW-212-12-G-Q male vertical header on 5.08 mm pitch mates with SAMTEC's compatible 24-way female socket housings designed for the same dual-row 0.200" pitch. Common mating options include discrete female socket strips and IDC or crimp housing assemblies on 5.08 mm centers. Verify contact gender and 24-way dual-row footprint match before selecting an alternative mating connector from other manufacturers.
