Frequently Asked Questions
How does the 5.08 mm pitch of the TSW-212-20-G-D accommodate high-current or high-density wiring needs?
The 5.08 mm center-to-center pitch of the TSW-212-20-G-D provides adequate spacing for up to 24 contacts in a dual-row layout, supporting wire gauges up to 22 AWG per contact. The 2.3 inch body length allows routing of multiple signal and power lines simultaneously in industrial control and test rack applications.
What mating connector types are compatible with the TSW-212-20-G-D for building modular board stacks?
The TSW-212-20-G-D male receptacle mates with standard 5.08 mm pitch dual-row pin headers, enabling modular board stack assemblies. Its 24 positions accommodate 12 signals per row, and gold-over-nickel contact finish maintains low contact resistance below 20 mΩ after 100 mating cycles.
Why choose TSW-212-20-G-D for prototype development boards requiring repeated connector insertions?
Gold-over-nickel plating on the TSW-212-20-G-D contacts provides durability across repeated mating cycles, typically rated for 200 or more insertions, maintaining reliable contact resistance. The vertical through-hole mounting with 5.08 mm pitch allows use of standard 0.2 inch grid protoboards and breakout boards during development.
In which environmental or industrial conditions does the gold contact finish of the TSW-212-20-G-D provide a performance advantage?
Gold-over-nickel plating resists oxidation and corrosion in humid or mildly harsh industrial environments, making the TSW-212-20-G-D reliable across -55°C to +125°C temperature ranges. In factory automation, test fixtures, and instrumentation enclosures exposed to temperature cycling or elevated humidity, gold contacts maintain stable electrical continuity better than tin-plated alternatives.
