What are the key features of TSM-135-04-STL-DH-A-P-TR?
- 70-position dual-row surface-mount terminal strip on 0.100 inch (2.54 mm) pitch, providing high pin density for compact PCB signal interface assemblies
- Straddle-mount (STL) mounting style allows the connector to straddle the PCB edge, reducing board overhang and enabling slim-profile enclosure designs
- Tape-and-reel (TR) packaging supports automated pick-and-place assembly lines for high-volume production with consistent component orientation and feed reliability
What is TSM-135-04-STL-DH-A-P-TR used for?
The TSM-135-04-STL-DH-A-P-TR is ideal for high-pin-count backplane interfaces, daughter card edge connections, and test fixture contact strips in embedded computing and industrial I/O expansion boards. Its 70-position 2.54 mm pitch dual-row layout efficiently routes 70 signals across a single connector footprint, reducing PCB connector count in data acquisition, FPGA development, and communication router board designs.

Frequently Asked Questions
How many positions and what pitch does the TSM-135-04-STL-DH-A-P-TR provide for signal routing?
The TSM-135-04-STL-DH-A-P-TR has 70 total positions arranged in a dual-row configuration on a 0.100 inch (2.54 mm) standard pitch. With 35 positions per row, the connector spans approximately 88.9 mm (3.5 inches) in length, enabling high-density routing of 70 signal lines across a single connector for backplane, daughter card, and test fixture interface applications.
What does the straddle-mount (STL) style mean for PCB layout, and how does it differ from vertical surface-mount headers?
In a straddle-mount configuration, the TSM-135-04-STL-DH-A-P-TR mounts over the edge of the PCB so that solder tails on both sides of the board anchor the connector mechanically and electrically. Unlike a vertical surface-mount header where all pads are on the top surface, the straddle-mount style distributes solder pads to both top and bottom PCB surfaces, improving pull-out force retention by approximately 2x compared to single-side SMT headers while reducing the connector's above-board height profile.
When is the TSM-135-04-STL-DH-A-P-TR tape-and-reel packaging preferred over tray packaging for production?
Tape-and-reel (TR) packaging is preferred when the production volume exceeds approximately 500 units per batch and an automated SMT pick-and-place machine is used. The reel format ensures each of the 70-position connectors is presented at a consistent orientation with controlled spacing, enabling machine placement at rates of 2000 to 5000 components per hour. Tray packaging is typically used for prototyping or low-volume hand-assembly where reel handling equipment is unavailable.
