What are the key features of TST-106-03-L-D?
- 12-position dual-row shrouded header at 0.100 inch pitch with 0.9 inch body provides mechanical keying and polarization to prevent mis-mating in cable-to-board and board-to-board applications
- Gold (10 microinch) over nickel mating contact finish on square pin contacts ensures low contact resistance and corrosion resistance across thousands of mating cycles
- Through-hole vertical mounting with tin-over-nickel termination delivers robust solder joint strength, making it resistant to mechanical stress and vibration in industrial environments
What is TST-106-03-L-D used for?
The TST-106-03-L-D is commonly used in industrial control systems, test and measurement equipment, and embedded computing platforms requiring reliable 12-position board-to-cable or board-to-board connections at 0.100 inch pitch. Its shrouded dual-row housing with gold-plated mating contacts suits applications like PLC I/O modules, sensor interface boards, and development kit expansion headers where repeated connector mating is expected. The compact 0.9 inch body length allows multiple connectors to be placed side by side on standard PCB form factors.

Frequently Asked Questions
What contact finish does TST-106-03-L-D use for the mating interface, and how does it affect connector reliability?
The TST-106-03-L-D uses gold (10 microinch) over nickel mating contacts on phosphor bronze square pin conductors. Gold plating provides excellent corrosion resistance and maintains contact resistance well below 20 mΩ even after hundreds of mating cycles, making it suitable for high-reliability applications such as test fixtures, PLC expansion modules, and sensor interface cards where consistent signal integrity is required over the product lifetime.
How does the shrouded housing of TST-106-03-L-D improve assembly accuracy compared to unshrouded dual-row headers?
The shrouded housing on the TST-106-03-L-D surrounds all 12 pins within the 0.9 inch body, providing a physical guide wall that aligns IDC ribbon cable connectors and mating receptacles during insertion. This prevents off-by-one row errors that are common with unshrouded 0.100 inch pitch dual-row headers, which is critical in manufacturing environments where operators are connecting multiple similar connectors on the same PCB under time pressure.
For a PLC expansion module needing 12 digital I/O lines, when is TST-106-03-L-D preferable to a screw terminal block?
TST-106-03-L-D is preferable to a screw terminal block when the I/O module requires standard IDC ribbon cable connections rather than individual wire terminations, reducing field wiring time from minutes to seconds per connector. The 0.100 inch pitch dual-row header mates directly to mass-termination ribbon cable assemblies carrying up to 12 signals, and the gold-plated contacts maintain reliable connectivity over the module's service life without periodic re-torquing that screw terminals require.
What is the body length of TST-106-03-L-D, and how does it compare to higher pin count TST-128 series connectors in board layout planning?
The TST-106-03-L-D has a body length of 0.9 inch (22.9 mm) and a body breadth and depth each of 0.365 inch (9.27 mm). Compared to the TST-128 series at 3.1 inches body length for 56 positions, the TST-106 is approximately 3.4 times shorter, making it easier to fit multiple 12-position connectors across a PCB edge or within a card cage slot without exceeding standard form factor constraints for industrial control boards.
