Frequently Asked Questions
How many signal positions does the TSM-127-01-SS-DH-A-K-TR provide, and what is its pin pitch?
The TSM-127-01-SS-DH-A-K-TR provides 54 positions in a dual-row arrangement with a standard 2.54mm (0.100 inch) pitch. This configuration supports a wide variety of digital and analog signal lines on a single connector, making it well suited for development boards, embedded modules, and test fixture interconnects where many signals must be routed in a compact footprint.
How does the tape-and-reel packaging of the TSM-127-01-SS-DH-A-K-TR benefit high-volume PCB manufacturing?
The -TR suffix designates tape-and-reel delivery, enabling the TSM-127-01-SS-DH-A-K-TR to be fed directly into automated pick-and-place machines. This reduces manual placement errors for the 54-position, 2.54mm pitch surface mount connector, improving throughput and consistency in high-volume SMT production lines compared to bulk or tray-packaged alternatives.
What distinguishes the dual-row DH configuration of the TSM-127-01-SS-DH-A-K-TR from single-row terminal strips?
The dual-row DH configuration doubles the contact density per unit of PCB length compared to a single-row strip at the same 2.54mm pitch. For the TSM-127-01-SS-DH-A-K-TR this means 54 positions are packed into approximately 34.29mm (27 positions per row x 1.27mm row pitch), enabling more signal lines in less board space, which is advantageous in communication and embedded computing card designs.
