Frequently Asked Questions
What is the pitch and total number of positions on the TSM-120-02-SM-DH-A-K-TR connector?
The TSM-120-02-SM-DH-A-K-TR features a 0.100 inch (2.54 mm) pitch with 40 positions arranged in a dual-row configuration, providing 20 pins per row for high-density surface mount interconnect applications.
How does the double-height (DH) design of the TSM-120-02-SM-DH-A-K-TR benefit PCB stacking applications?
The double-height feature adds approximately 4.57 mm of additional standing height compared to standard SMT terminal strips, allowing designers to stack two PCBs with adequate clearance for through-board components. This is critical in compact embedded systems requiring board-to-board signal routing across 40 circuits.
Is the TSM-120-02-SM-DH-A-K-TR compatible with automated SMT assembly lines?
Yes, the -TR suffix indicates tape-and-reel packaging, making the TSM-120-02-SM-DH-A-K-TR fully compatible with automated pick-and-place equipment used in high-volume SMT assembly. With 40 positions and surface mount tails, it is suitable for production runs requiring consistent placement accuracy of ±0.05 mm or better.
Which SAMTEC series can serve as an alternative or mating connector for the TSM-120-02-SM-DH-A-K-TR?
SAMTEC's TSW and TSM series connectors with 0.100 inch (2.54 mm) pitch are compatible mating options. The TSM-120-02-SM-DH-A-K-TR mates with standard 40-pin dual-row headers in the same pitch family, offering multiple contact finish options including gold plating on 30 micro-inches for low-resistance connections.
