Frequently Asked Questions
How many positions does the TSW-212-20-G-Q provide and what pitch does it use?
The TSW-212-20-G-Q is a 24-way single-row vertical receptacle header with a 5.08 mm (0.2 inch) contact pitch. This standard pitch ensures compatibility with common 0.1-inch ribbon cables and mating pin headers used across industrial, prototyping, and embedded computing platforms, providing reliable multi-signal interconnection in a single connector.
For high-cycle industrial applications, how durable is the contact finish on TSW-212-20-G-Q?
The TSW-212-20-G-Q features gold-over-nickel contact finish on both mating and termination surfaces, offering corrosion resistance and low contact resistance typically below 20 mΩ. Gold plating sustains reliable electrical performance across 500 or more mating cycles, making this connector suitable for industrial equipment panels, modular instrumentation, and frequently reconfigured test fixtures.
Is the TSW-212-20-G-Q suitable for automated PCB assembly, and how is it mounted?
The TSW-212-20-G-Q uses through-hole mounting with a body length of 2.3 inches and body depth of 0.1 inch, allowing insertion into standard 2.54 mm drilled PCB holes and wave or selective soldering during automated assembly. Through-hole mounting provides significantly stronger pull-out force than SMD connectors, typically exceeding 10 N per pin in populated boards.
When would a designer choose TSW-212-20-G-Q over a lower-pitch connector in a multi-signal backplane?
A designer selects TSW-212-20-G-Q with its 5.08 mm pitch when the application requires larger wire gauges up to AWG 22, higher current capacity per contact, or easier manual wiring in field-serviceable industrial enclosures. The wider 5.08 mm spacing also reduces crosstalk between adjacent signal lines compared to 2.54 mm pitch alternatives at frequencies below 100 MHz.
