Key Features
- 72-position dual-row SMT terminal strip at 0.100" pitch for maximum connectivity density in a single connector
- Alignment key (K suffix) prevents misinsertion, protecting all 72 contacts in high-cycle mating applications
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place assembly lines for production efficiency
Applications
The TSM-136-03-S-DH-A-K-TR is designed for high-density module-to-backplane and board-to-board interconnect in server, telecommunications, and industrial automation systems requiring 72 simultaneous connections on a 0.100-inch pitch. Its alignment key ensures correct mating orientation, reducing field failures in rack-mount and embedded computing platforms. Tape-and-reel delivery supports seamless integration into automated SMT assembly lines for high-volume manufacturing.

Frequently Asked Questions
How many contact positions does the TSM-136-03-S-DH-A-K-TR provide, and how are they arranged?
The TSM-136-03-S-DH-A-K-TR offers 72 positions in a dual-row configuration at 0.100-inch pitch, giving 36 contacts per row. This high-density layout accommodates complex multi-rail power distribution and parallel data bus interfaces within a footprint of approximately 3.6 inches in length on the PCB.
For a server backplane design carrying 72 differential pairs, how does the TSM-136-03-S-DH-A-K-TR reduce assembly errors?
The alignment key (K suffix) on the TSM-136-03-S-DH-A-K-TR provides a physical anti-rotation feature that mechanically prevents the connector from being seated in the wrong orientation. In a 72-position dual-row connector handling differential data pairs, a single misalignment event could damage all contacts, so the key is a critical reliability feature for server and telecom backplane assemblies.
What makes the TSM-136-03-S-DH-A-K-TR more suitable for high-volume production than through-hole alternatives with a similar 72-position count?
As a surface mount connector in tape-and-reel (TR) packaging, the TSM-136-03-S-DH-A-K-TR is directly compatible with automated pick-and-place equipment, eliminating manual insertion and wave soldering steps required for through-hole 72-position connectors. This reduces assembly cycle time and labor cost per board in production runs exceeding 1000 units.
