Key Features
- 22-position dual-row shrouded PCB header with 0.100 inch (2.54 mm) pitch, offering polarized mating to prevent incorrect connector orientation
- Gold (30 microinch) over nickel mating contact finish ensures low, stable contact resistance and corrosion resistance over thousands of mating cycles
- Rectangular contact pattern with SQ pin-socket style in a 1.4 inch body accommodates standard 0.100 inch pitch ribbon cable and socket assemblies
Applications
The TST-111-02-S-D is designed for board-to-board and wire-to-board connections in industrial automation, embedded systems, and test and measurement equipment requiring 22 reliable signal paths at 0.100 inch pitch. Its shrouded design makes it a preferred choice for field-replaceable module interfaces and development platforms where polarized mating is essential to prevent connection errors. Gold-plated mating contacts ensure consistent performance in environments subject to vibration or frequent connector cycling.

Frequently Asked Questions
What contact finish is used on the mating versus termination side of TST-111-02-S-D and why does this combination matter?
The TST-111-02-S-D uses 30 microinch gold over nickel on mating contacts for low contact resistance and corrosion resistance, while termination contacts use tin over nickel for reliable solderability. This combination maximizes connection reliability on the mating interface while keeping board soldering straightforward during PCB assembly.
For a 22-signal embedded module interface, how does the shrouded housing of TST-111-02-S-D help prevent assembly errors?
The shrouded housing physically guides the mating socket to the correct 22-position, 0.100 inch pitch alignment and prevents reverse insertion. This polarization feature is critical in industrial and embedded designs where incorrect connections could damage modules or disrupt system operation during initial assembly or field maintenance.
In which procurement and design scenarios would a 22-position TST-111-02-S-D be selected over a 20-position header such as TST-110-03-H-D?
A designer selects the 22-position TST-111-02-S-D when signal bus requirements exceed 20 connections, such as in a 16-bit data bus combined with power and control lines on a 0.100 inch pitch ribbon interface. The extra 2 positions provide flexibility for additional ground, power, or reserved lines without needing a larger 24 or 26-position connector.
