Frequently Asked Questions
How many positions and rows does the TSM-127-04-STL-DH-A-K-TR have, and what is its pitch?
The SAMTEC TSM-127-04-STL-DH-A-K-TR is a 54-position, dual-row terminal strip with a 2.54mm (0.100") pitch. This configuration provides 27 contacts per row, enabling high-density signal routing while maintaining compatibility with standard 2.54mm grid PCB layouts common in industrial and computing applications.
Why does TSM-127-04-STL-DH-A-K-TR use a surface-mount with through-hole tail design instead of pure SMT?
The combined surface-mount body with through-hole tails on the TSM-127-04-STL-DH-A-K-TR delivers mechanical anchoring strength that pure SMT pads cannot match. Through-hole tails resist up to several Newtons of extraction force and provide stability against PCB flexing, vibration, and connector mating forces, making it suitable for rugged industrial and telecom environments operating from -55°C to +125°C.
For a high-volume production line, what packaging does the TSM-127-04-STL-DH-A-K-TR use to support automated assembly?
The -TR suffix indicates tape-and-reel packaging, allowing automated pick-and-place machines to place the 54-position connector at high speed with consistent orientation. Standard reel sizes typically carry 250 to 500 pieces per reel, reducing manual handling and improving throughput on SMT lines running at rates above 10,000 placements per hour.
