Frequently Asked Questions
What is the pin pitch and row configuration of the TSM-127-02-LM-DH-A-K-TR?
The TSM-127-02-LM-DH-A-K-TR uses a 0.100-inch (2.54 mm) pitch dual-row layout with 54 total positions (27 per row), making it compatible with standard 0.100-inch grid PCB designs common in industrial and instrumentation applications.
Which PCB assembly processes are compatible with the TSM-127-02-LM-DH-A-K-TR?
This connector is designed for surface mount technology (SMT) assembly and is supplied in tape-and-reel (TR) format to support automated pick-and-place machines, with a reflow soldering process compatible with standard 250°C peak profiles.
How does the TSM-127-02-LM-DH-A-K-TR compare to through-hole terminal strips for high-density designs?
Compared to through-hole variants, the TSM-127-02-LM-DH-A-K-TR eliminates the need for 54 drilled holes, reducing PCB layer constraints and enabling routing on both sides; its 3A per pin current rating matches typical through-hole equivalents while occupying less board area.
In what voltage range can the TSM-127-02-LM-DH-A-K-TR safely operate?
The TSM-127-02-LM-DH-A-K-TR is rated for 250V AC dielectric withstanding voltage, supporting signal and low-voltage power connections up to this level, which covers most industrial control, sensor interface, and embedded computing use cases.
