Frequently Asked Questions
How many signal connections can the TSM-135-04-SM-DH-A-K-TR support in a single connector?
The TSM-135-04-SM-DH-A-K-TR provides 70 positions arranged in a dual-row configuration with .100" (2.54 mm) pitch, enabling up to 70 individual signal or power connections in a single compact surface-mount terminal strip footprint.
What packaging format does the TSM-135-04-SM-DH-A-K-TR use and how does it affect production efficiency?
The TR suffix indicates tape-and-reel packaging, compatible with automated pick-and-place SMT assembly lines. This allows high-volume PCB production with the 70-position, 2.54 mm pitch connector without manual insertion, reducing assembly time and placement errors.
In what types of industrial designs is a 70-position .100" dual-row terminal strip like the TSM-135-04-SM-DH-A-K-TR typically specified?
Industrial control panels, embedded computing backplanes, and test and measurement instrumentation typically specify 70-position dual-row connectors at 2.54 mm pitch. These applications require reliable interconnects for 70 or more signal channels while maintaining a standard PCB footprint for ease of layout and assembly.
