What are the key features of TSM-127-02-FM-DH-A-K-TR?
- 54-position dual-row 0.100" pitch female surface mount terminal strip for reliable board-level signal distribution
- K keep-out option maintains required component clearance zone for trouble-free SMT reflow soldering
- Tape-and-reel (TR) packaging enables high-speed automated pick-and-place assembly with consistent placement accuracy
- DH dual-height configuration supports stacked board applications requiring precise vertical board separation
What is TSM-127-02-FM-DH-A-K-TR used for?
The TSM-127-02-FM-DH-A-K-TR is suited for high-density signal interconnection in embedded computing systems, FPGA development boards, and modular instrumentation where 54 contacts at 0.100" pitch are required across dual rows. Its female contact design mates with standard 0.100" male pin headers used in industrial PLCs, robotics controllers, and test equipment daughter cards. The keep-out and tape-and-reel options make it ideal for automated SMT assembly lines producing high-reliability electronics for medical and defense markets.

Frequently Asked Questions
What is the total pin count and row configuration of the TSM-127-02-FM-DH-A-K-TR?
The TSM-127-02-FM-DH-A-K-TR provides 54 positions arranged in a dual-row (DH) configuration with a 0.100" (2.54 mm) pitch, with 27 contacts per row, making it suitable for applications requiring up to 54 signal or power connections in a standard grid layout.
In which production environments is the tape-and-reel packaging of TSM-127-02-FM-DH-A-K-TR most advantageous?
The TR (tape-and-reel) packaging is most beneficial in SMT production lines running volumes above 500 boards per shift, enabling automated placement rates of 5,000 to 12,000 connectors per hour at 0.100" pitch accuracy, significantly reducing per-unit assembly cost compared to manual tray-fed assembly.
How does the keep-out (K) option on TSM-127-02-FM-DH-A-K-TR affect routing and placement rules in PCB design?
The K option reserves a specific clearance area of at least 0.100" from the connector body edges, which PCB designers must incorporate as a component exclusion zone to prevent adjacent SMT components from interfering with connector seating or causing solder bridges across the 54 contact pads during reflow.
When would a designer choose TSM-127-02-FM-DH-A-K-TR over a lower pin-count terminal strip for an FPGA carrier board?
An engineer would select the 54-position TSM-127-02-FM-DH-A-K-TR when an FPGA module requires more than 40 I/O signals plus power and ground pins routed through a single 0.100" pitch female connector, avoiding the complexity of multiple smaller connectors while maintaining a compact 2.54 mm pitch standard footprint.
