Frequently Asked Questions
How many positions does the TST-120-02-T-D connector provide and in what row configuration?
The TST-120-02-T-D has 40 positions arranged in a dual-row 20×2 layout on a 0.100-inch pitch, delivering a dense signal interface in a 2.3-inch body length suitable for compact PCB designs.
What contact material and finish does the TST-120-02-T-D use for reliable mating?
Contacts are made of phosphor bronze and finished with matte tin over a nickel barrier, providing corrosion resistance and low contact resistance across multiple insertion cycles in test and instrumentation environments.
When would TST-120-02-T-D be preferred over a surface-mount connector variant for a test fixture?
Through-hole mounting of the TST-120-02-T-D gives stronger mechanical retention than SMT alternatives, which matters in test fixtures that undergo repeated plug-unplug operations. The 1-week lead time also supports rapid prototype and small-series production schedules.
