Frequently Asked Questions
What pitch and contact count does the TSM-120-03-FM-DH-A-K-TR provide?
The TSM-120-03-FM-DH-A-K-TR is a 40-position dual-row terminal strip on a 0.100" (2.54 mm) pitch, offering a standard grid footprint that integrates easily with through-hole or surface-mount compatible PCB layouts in industrial and embedded applications.
Why choose tape-and-reel packaging for the TSM-120-03-FM-DH-A-K-TR in production?
The TR tape-and-reel format allows automated pick-and-place machines to handle the 40-position dual-row connector without manual loading, significantly improving throughput. This packaging is standard for SMT assembly lines processing hundreds or thousands of boards per production run.
How do the female machined contacts in this SAMTEC terminal strip compare to stamped contacts?
Female machined (FM) contacts provide tighter dimensional tolerances and a more consistent contact surface than stamped contacts. This results in lower and more stable contact resistance over repeated mating cycles, making the TSM-120-03-FM-DH-A-K-TR preferable in instrumentation or test equipment requiring reliable 40-channel connectivity.
What applications benefit most from the TSM-120-03-FM-DH-A-K-TR dual-row layout?
Applications requiring high-density signal routing across 40 positions in a 0.100" grid are ideal matches, including embedded computing backplanes, industrial I/O modules, and data acquisition front-ends. The dual-row surface-mount design reduces board footprint compared to single-row alternatives while maintaining compatibility with standard 2.54 mm spacing.
