Key Features
- 56-position dual-row female terminal strip at 0.100 inch (2.54 mm) pitch for high pin-count SMT board interconnects
- Staggered through-hole (STL) solder leads for enhanced mechanical retention and PCB anchoring strength
- Polarized (P) housing prevents mis-mating and ensures correct insertion orientation during assembly
- Tape-and-reel (TR) packaging for seamless integration into automated SMT pick-and-place production lines
Applications
TSM-128-02-STL-DH-A-P-TR is suited for backplane interconnects, FPGA daughter boards, and industrial I/O modules where a 56-pin 2.54 mm pitch dual-row female connector with mechanical board retention is needed. The polarized housing and staggered through-hole tails make it popular in vibration-prone environments such as robotics controllers and motor drive panels requiring reliable signal and power termination.

Frequently Asked Questions
How many positions does TSM-128-02-STL-DH-A-P-TR have and what is its contact pitch?
TSM-128-02-STL-DH-A-P-TR is a 56-position dual-row surface-mount terminal strip with a 0.100 inch (2.54 mm) contact pitch, providing 28 contacts per row. This is the most common PCB header pitch in embedded electronics, ensuring broad compatibility with standard dual-row male headers from multiple connector manufacturers.
What does the STL feature in TSM-128-02-STL-DH-A-P-TR provide?
The STL (staggered through-hole lead) designation means TSM-128-02-STL-DH-A-P-TR includes additional staggered solder tails that pass through the PCB and are soldered in the through-holes, dramatically increasing the connector's mechanical retention strength. This is especially important for 56-pin connectors in industrial and ruggedized systems subject to mechanical stress, vibration, or repeated mating cycles.
What production benefits does the TR packaging offer for TSM-128-02-STL-DH-A-P-TR?
The TR (tape and reel) suffix indicates TSM-128-02-STL-DH-A-P-TR is supplied on standard reel packaging, making it compatible with automated pick-and-place machines used in SMT production lines. This reduces manual placement time and error rates significantly when assembling boards in quantities of hundreds or thousands, and is essential for lean, high-throughput electronics manufacturing.
When should a designer choose TSM-128-02-STL-DH-A-P-TR over a standard SMT-only connector?
TSM-128-02-STL-DH-A-P-TR is preferred when a 56-position, 2.54 mm pitch connector must withstand connector mating forces and vibration without lifting off the PCB. The staggered through-hole tails (STL) add significant pull and shear strength compared to surface-mount-only pads, making this part the better choice for industrial panels, test fixtures, and robotics systems that endure repeated plugging cycles.
