Frequently Asked Questions
How many positions does the TSM-135-04-S-DH-A-K-TR provide and how are they arranged?
The TSM-135-04-S-DH-A-K-TR provides 70 positions arranged in a dual-row configuration at a 2.54 mm (.100 inch) pitch, giving designers 35 pins per row for high-density interconnect on a single PCB footprint.
What does the tape-and-reel packaging (TR suffix) mean for automated SMT assembly lines?
The TR suffix indicates the connector is supplied in tape-and-reel format, supporting automated pick-and-place equipment. With 2.54 mm pitch contacts and surface mount termination, it integrates directly into standard SMT reflow processes without hand-placement.
Which board-to-board or backplane designs benefit most from this 70-position SAMTEC terminal strip?
High-density backplane assemblies, embedded computing modules, and industrial controller boards benefit most. The 70-position count covers 35 signals per row at 2.54 mm pitch, handling parallel data buses, power rails, and control lines in a single compact SMT connector footprint.
