Frequently Asked Questions
How many total contacts does the TSM-127-03-TL-DH-A-K-TR provide and what is the pin pitch?
The TSM-127-03-TL-DH-A-K-TR is a 54-position dual-row connector providing 108 total contacts on the standard 2.54 mm (0.100") pitch. This density accommodates 54 signal or power pairs on a single SMT header, making it suitable for high-count digital bus interfaces and parallel data links in embedded board designs.
What packaging format does the TSM-127-03-TL-DH-A-K-TR use and how does it benefit production assembly?
The TR suffix indicates tape-and-reel packaging, with connectors on 8 mm, 12 mm, or 16 mm carrier tape depending on body width. Tape-and-reel format enables automated pick-and-place machines to populate 108-contact SMT terminal strips at rates of 2000 to 5000 placements per hour, significantly reducing hand-assembly labor costs in volume manufacturing.
Which mating connectors are compatible with the TSM-127-03-TL-DH-A-K-TR for board-to-cable or board-to-board connections?
The TSM-127-03-TL-DH-A-K-TR mates with Samtec FTS, CLM, and SDR series cable connectors or opposing TSM header footprints on a mating PCB, all sharing the 2.54 mm dual-row pitch. IDC ribbon cable assemblies on 54-position 0.100" connectors also mate directly, supporting up to 3 A per contact for power distribution in backplane or cable harness applications.
