Frequently Asked Questions
What is the contact pitch and total pin count of the TSM-120-02-SS-DH-A-K-TR?
The TSM-120-02-SS-DH-A-K-TR features a 2.54 mm (.100") contact pitch with 40 pins total arranged in a dual-row (2 rows x 20 columns) configuration, making it suitable for high-density SMT board-to-board interconnect applications.
How does the stainless steel contact material in TSM-120-02-SS-DH-A-K-TR benefit industrial designs?
Stainless steel contacts provide superior corrosion resistance compared to standard brass contacts, enabling reliable signal integrity at temperatures up to 105°C in harsh industrial environments where exposure to moisture, chemicals, or oxidizing agents is a concern.
When should a designer choose TSM-120-02-SS-DH-A-K-TR over a through-hole terminal strip for backplane assemblies?
Designers should choose this SMT strip when board thickness is limited to under 1.6 mm or when the PCB layout requires components on both sides of the board; the surface mount footprint eliminates drilled holes, saving approximately 0.8 mm of board thickness and simplifying layer routing for 40-pin interconnects.
Is the TSM-120-02-SS-DH-A-K-TR supplied in tape-and-reel format suitable for automated assembly lines?
Yes, the -TR suffix confirms tape-and-reel packaging, compatible with standard SMT pick-and-place machines at reel quantities typically of 500 or 1000 units per reel, supporting high-volume production rates of hundreds of boards per hour with standard 2.54 mm pitch feeders.
