What are the key features of TST-120-02-T-D?

  • Dual-row 40-position (20×2) configuration with 0.100" pitch for dense signal interconnects
  • Phosphor bronze contacts with matte tin over nickel finish for reliable low-resistance mating
  • Through-hole termination with 1-week factory lead time for quick-turn board assembly

What is TST-120-02-T-D used for?

The TST-120-02-T-D is designed for board-to-board and board-to-module interconnects in instrumentation, test fixtures, and embedded computing systems requiring 40 reliable signal paths. Its dual-row through-hole configuration suits backplane connectors, evaluation board headers, and JTAG or debug interface sockets in both prototype and production hardware. The tin-over-nickel contact finish ensures consistent performance across repeated mating cycles in industrial and lab environments.

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.
