What are the key features of TST-111-01-T-D?
- 22-position dual-row shrouded header at 0.100" (2.54 mm) pitch with square-pin contacts, providing a standard and cost-effective solution for PCB-to-cable and PCB-to-PCB interconnects
- Tin (200 µin) over nickel mating contact finish on square pins offering robust corrosion resistance and reliable electrical connection for industrial operating environments
- Compact 1.4" body length shrouded housing with keyed polarization preventing reverse mating, suitable for field-serviceable assemblies in control panels and embedded systems
What is TST-111-01-T-D used for?
The TST-111-01-T-D is well suited for board-to-ribbon-cable connections in industrial automation controllers, embedded single-board computers, and consumer electronics where a cost-effective 22-position 0.100" pitch shrouded header is required. Its tin-plated square-pin contacts provide reliable contact with standard IDC socket connectors over many mating cycles. Through-hole mounting ensures mechanical stability in environments subject to cable strain or moderate vibration.

Frequently Asked Questions
How many contacts does the TST-111-01-T-D have, and what contact finish is specified?
The TST-111-01-T-D has 22 positions in a dual-row (11 per row) layout at 0.100" (2.54 mm) pitch with square-pin male contacts finished in tin (200 µin) over nickel for the mating interface and tin over nickel for termination. The 200 µin tin thickness provides durable corrosion resistance over repeated mating cycles in industrial environments.
What is the body length of the TST-111-01-T-D and how does this affect PCB layout?
The TST-111-01-T-D has a body length of 1.4" (35.6 mm) and a body breadth of 0.365" (9.27 mm). Engineers must allocate this footprint on the PCB with sufficient clearance for IDC cable strain relief, typically leaving at least 15 mm of free board space beyond the connector body for cable routing in compact control board designs.
In which scenarios would the TST-111-01-T-D offer a cost advantage over gold-plated shrouded headers?
The TST-111-01-T-D uses tin (200 µin) over nickel contacts rather than gold plating, reducing component cost while still delivering reliable connection for applications with fewer than 50 mating cycles. This makes it economically attractive for industrial panels, HVAC controllers, and embedded modules where connectors are mated only during manufacturing or periodic maintenance, unlike high-cycle test fixtures that require gold contacts.
Which mating connectors work with the TST-111-01-T-D at 0.100" pitch?
The TST-111-01-T-D is compatible with SAMTEC SSW series dual-row 0.100" pitch socket connectors as well as standard 22-conductor IDC ribbon cable assemblies using 2.54 mm pitch flat cable. IDC socket housings from manufacturers such as TE Connectivity and Amphenol that match the 2x11 pin layout at 2.54 mm pitch are also electrically and mechanically compatible, giving procurement teams multiple sourcing options at competitive prices.
