Key Features
- 72-position dual-row surface mount terminal strip at 2.54 mm (0.100") pitch
- Low-profile (LM) housing reducing overall stack height in compact PCB assemblies
- Dual-height (DH) design accommodating daughter cards or mating connectors of varied heights
- Keying (K) feature preventing incorrect mating and protecting 72-position signal integrity
- Tape and reel (TR) packaging enabling automated high-volume SMT assembly
Applications
The TSM-136-01-LM-DH-A-K-TR is suited for high-density signal routing in industrial controller backplanes, embedded computing boards, and communications infrastructure equipment where a 72-position SMT terminal strip with mechanical keying is required. Its low-profile dual-height construction is ideal for space-constrained designs that need reliable interconnect between stacked PCBs while preventing mismatings during automated assembly and field maintenance.

Frequently Asked Questions
How does the K (keying) feature in TSM-136-01-LM-DH-A-K-TR prevent assembly errors across 72 positions?
The K keying feature introduces a mechanical polarization element that physically blocks incorrect insertion of the mating connector on any of the 72 positions at 2.54 mm pitch. This prevents reversed or shifted mating during high-volume SMT assembly and field servicing, protecting sensitive digital or analog signal lines from short circuits caused by misalignment.
What is the height advantage of the LM low-profile housing on TSM-136-01-LM-DH-A-K-TR compared to standard TSM connectors?
The LM low-profile housing reduces the above-board height compared to standard TSM variants, enabling the 72-position connector to fit within tight vertical clearances in stacked PCB designs. When combined with the DH dual-height feature, designers gain approximately 2 to 3 mm of additional flexibility in mating connector compatibility at 2.54 mm pitch.
For a system requiring 72 discrete signal lines between boards, how does TSM-136-01-LM-DH-A-K-TR compare to using multiple smaller connectors?
A single TSM-136-01-LM-DH-A-K-TR consolidates 72 signals into one 2.54 mm pitch dual-row footprint spanning approximately 46 mm, eliminating multiple connector pairs and simplifying PCB routing. This reduces the number of solder joints by replacing four 18-position connectors with one unit, improving reliability and reducing board assembly cost in industrial and embedded computing applications.
