Key Features
- 56-position dual-row shrouded header at 0.100" (2.54 mm) pitch providing keyed, high pin-count connectivity in industrial and embedded computing applications
- High-profile (H) shroud variant offering extra mechanical protection around the 28-pins-per-row contact array, reducing contact damage risk during cable insertion in field environments
- Through-hole vertical termination delivering strong solder joint integrity for connectors subjected to repeated cable mating cycles or cable strain in equipment with frequent maintenance
Applications
The TST-128-05-H-D is used in industrial PLCs, single-board computers, and data acquisition systems requiring 56-pin dual-row connectivity at the standard 0.100" pitch with reliable IDC cable interface. Its high-profile shroud protects the contact array in panel-mounted or rack-mounted equipment where cables are frequently connected and disconnected. Through-hole mounting ensures robust mechanical anchoring in vibration-prone environments such as factory automation and motor control cabinets.

Frequently Asked Questions
How many total positions does the TST-128-05-H-D provide and how are they arranged?
The TST-128-05-H-D provides 56 positions arranged in 2 rows of 28 pins at a 0.100" (2.54 mm) pitch. This configuration is compatible with standard 56-way IDC ribbon cable assemblies and dual-row socket connectors, enabling high pin count board-to-cable interfaces in industrial control and computing systems.
What does the H designation mean in TST-128-05-H-D and how does it affect usability?
The H designation indicates a high-profile shroud variant with a taller housing than the standard TST series. The taller shroud provides additional mechanical protection for the 56 contacts and facilitates easier cable alignment during mating, reducing insertion errors in production environments where operators work with 56-pin IDC assemblies at 0.100" pitch under time pressure.
Can the TST-128-05-H-D withstand repeated mating cycles in field-serviceable equipment?
Yes, the TST-128-05-H-D is rated for multiple mating cycles and uses through-hole termination to anchor the connector firmly to the PCB, resisting cable pull forces during unmating. Gold-plated contacts, where specified, maintain low contact resistance below 30 milliohms across at least 30 mating cycles, making the part appropriate for test fixtures, maintenance panels, and field-upgradeable industrial modules.
Which mating connectors and cable assemblies are compatible with the TST-128-05-H-D?
The TST-128-05-H-D mates with SAMTEC SSW or SFW series dual-row 0.100" pitch socket connectors and with standard 56-conductor IDC ribbon cable assemblies using 2.54 mm pitch flat cable. Compatible IDC cable assemblies are available in lengths from 150 mm to over 600 mm, providing flexible interconnect options for rack systems, backplane connections, and inter-board wiring in computing and automation equipment.
