Frequently Asked Questions
How many mating positions does the TSM-136-04-LM-DH-A-K-TR provide per row?
The TSM-136-04-LM-DH-A-K-TR is a dual-row connector providing 36 positions per row for a total of 72 positions, all on a 0.100" (2.54 mm) pitch centerline, making it suitable for high-density signal routing across PCBs.
Is TSM-136-04-LM-DH-A-K-TR suitable for automated pick-and-place assembly on SMT lines?
Yes, the TR suffix indicates tape and reel packaging, which is specifically designed for automated SMT pick-and-place assembly. The connector's surface mount footprint supports reflow soldering, enabling high-volume production with standard 0.100" pitch SMT equipment.
What contact finish does the TSM-136-04-LM-DH-A-K-TR use, and how does it affect long-term reliability?
The connector features gold-plated contacts, which provide corrosion resistance and low contact resistance over thousands of mating cycles. Gold plating is preferred in industrial and test environments where consistent signal integrity across 72 pins is critical.
Which SAMTEC mating connectors are compatible with the TSM-136-04-LM-DH-A-K-TR for a complete board-to-board interface?
The TSM series mates with SAMTEC SSQ or SMM series receptacles designed for 0.100" (2.54 mm) pitch dual-row headers. Selecting a 72-position receptacle (36 pins per row) ensures a complete 72-pin board-to-board interface for signal distribution in embedded systems.
