What are the key features of TSM-128-02-TM-DH-A-K-TR?
- 56-position dual-row layout at 0.100-inch (2.54mm) pitch provides broad signal connectivity for mid-density interface designs
- Top-mount (TM) orientation suits applications where connectors must be accessible from the component side of the PCB
- Kinked tail (K) contact termination increases solder joint pull strength and mechanical retention during board handling and vibration
What is TSM-128-02-TM-DH-A-K-TR used for?
The TSM-128-02-TM-DH-A-K-TR is designed for industrial automation, embedded computing, and communications equipment requiring reliable 56-pin SMT connections at the standard 0.100-inch grid pitch. The top-mount configuration and kinked tail contacts offer improved mechanical durability for boards subject to vibration or thermal cycling in harsh operating environments. Tape-and-reel packaging enables efficient automated SMT assembly across high-volume production runs.

Frequently Asked Questions
What does the TM suffix mean in TSM-128-02-TM-DH-A-K-TR and how does it affect PCB layout?
TM stands for top-mount, meaning the 56-position connector body sits above the PCB surface with contacts soldered to pads on the top layer, allowing access to mating connectors from the component side and simplifying routing on dense dual-sided PCB assemblies using 0.100-inch pitch grid.
How does the kinked tail contact design improve mechanical reliability of the TSM-128-02-TM-DH-A-K-TR solder joint?
The K (kinked tail) contact feature creates a mechanical interlocking shape in the contact termination that increases the solder joint pull-out force by distributing stress over a larger solder fillet area, improving resistance to mechanical shock and vibration compared to straight-tail contacts in the 56-position, 0.100-inch pitch SMT strip.
When would an engineer select TSM-128-02-TM-DH-A-K-TR over a lower position-count alternative?
With 56 positions in a dual-row, 0.100-inch pitch format, this terminal strip suits designs requiring more than 40 signal or power connections—such as FPGA I/O expansion boards, motor controller interfaces with multiple axis signals, or backplane modules carrying address, data, and control buses simultaneously on a single compact connector.
