Key Features
- 12-way right-angle configuration at 2.54 mm (0.100-inch) pitch enables horizontal cable routing in space-limited PCB enclosures
- Gold flash over nickel contact finish delivers corrosion resistance and consistent low contact resistance across multiple mating cycles
- Brass contact material ensures robust mechanical strength and stable electrical performance in vibration-prone industrial environments
Applications
The T821112A1R100CEU is used for cable harness termination and board-to-board interconnections in industrial controllers, embedded computing modules, and consumer electronics enclosures where a right-angle 12-pin header allows flat cable to exit parallel to the PCB surface. Its 2.54 mm pitch and gold-plated contacts support reliable multi-cycle mating in panel-mount and box-build assemblies.

Frequently Asked Questions
How many positions does the T821112A1R100CEU support and at what pitch for cable connections?
The T821112A1R100CEU is a 12-way (12-position) right-angle male header with a 2.54 mm (0.100-inch) pitch, accommodating standard IDC ribbon cables and crimp-style connectors commonly used in industrial control panels, development boards, and embedded system enclosures.
What contact finish is used on the T821112A1R100CEU and why does it matter for mating reliability?
The T821112A1R100CEU uses gold flash over nickel on both mating and termination surfaces, which provides corrosion protection and low contact resistance — typically below 30 mΩ — across repeated insertion cycles, ensuring reliable signal integrity in test fixtures, industrial I/O boards, and frequently serviced assemblies.
For a right-angle PCB header, how does the T821112A1R100CEU's orientation benefit enclosure design?
The right-angle orientation of the T821112A1R100CEU routes the 12-pin 2.54 mm pitch cable parallel to the PCB surface, enabling the mating cable to exit through a panel cutout horizontally without the connector extending perpendicular to the board — reducing overall assembly height in chassis-mounted industrial and communications equipment.
