Frequently Asked Questions
How does the 5.08mm pitch of the TSW-212-18-G-Q affect connector mating and compatibility with ribbon cables?
The 5.08mm pitch of the TSW-212-18-G-Q matches standard 0.2-inch spaced connectors widely used in industrial wiring and backplane designs, making it compatible with a range of mating female receptacles and ribbon cable connectors. This larger pitch compared to 2.54mm versions simplifies hand-assembly and reduces the risk of misalignment during mating, which is especially valuable in field-serviceable industrial panels and test equipment setups with 24 signal lines.
What contact finish does the TSW-212-18-G-Q use and how does this affect long-term connection reliability?
The TSW-212-18-G-Q uses gold over nickel contact finish on both the mating surface and the termination area, providing low and stable contact resistance across thousands of mating cycles. Gold plating resists oxidation and corrosion even in humid or mildly corrosive environments, making these 24-pin connectors reliable over the lifetime of test fixtures, development boards, and industrial modules where connector maintenance is infrequent.
Can the TSW-212-18-G-Q be used in high-cycle automated test equipment or only in static board-to-board setups?
The TSW-212-18-G-Q with its gold-over-nickel contact finish is well-suited for moderate-cycle automated test equipment (ATE) sockets and functional test fixtures in addition to static board-to-board installations. For ATE applications requiring thousands of insertions, the gold finish maintains contact integrity, and the 5.08mm pitch of this 24-way header provides the mechanical clearance needed for guided pin entry in automated handling systems.
