Frequently Asked Questions
How many positions does the TSM-126-04-LM-DH-A-K-TR have, and what is its pitch?
The TSM-126-04-LM-DH-A-K-TR is a 52-position dual-row terminal strip with a 0.100 inch (2.54 mm) pitch, giving it a compact layout suitable for high-density SMT board designs in industrial and communications applications.
What does the 'K' option in TSM-126-04-LM-DH-A-K-TR indicate, and why does it matter for SMT assembly?
The 'K' designator in the part number indicates a kinked contact tail, which provides a controlled standoff height above the PCB pad. This improves solder wetting inspection visibility and helps ensure reliable solder joints during automated reflow assembly of the 52-pin connector.
Which application sectors commonly use the TSM-126-04-LM-DH-A-K-TR terminal strip?
Industrial control systems, data acquisition hardware, and embedded computing backplanes frequently use this 52-position 2.54 mm pitch SMT strip. Its dual-row (DH) layout delivers a high I/O count in a small PCB area, making it practical for space-constrained designs with up to 52 signal or power contacts.
Is the TSM-126-04-LM-DH-A-K-TR packaged for automated pick-and-place assembly?
Yes, the TR suffix indicates tape-and-reel packaging, making the TSM-126-04-LM-DH-A-K-TR compatible with standard pick-and-place equipment. This packaging supports high-volume SMT assembly lines handling the 52-position 2.54 mm pitch connector without manual placement steps.
