What are the key features of TSM-127-02-H-DH-A-K-TR?
- 54-position (108-contact) dual-row layout on 0.100 inch (2.54 mm) pitch enabling dense signal routing in compact SMT assemblies
- Polarizing key (K) feature preventing incorrect connector orientation in high-pin-count 108-contact mating applications
- Tape-and-reel (TR) packaging for automated pick-and-place SMT assembly at high production volumes with standard reel feeders
- High-profile dual-height (H-DH) construction with gold-flash contact plating for low contact resistance and reliable repeated mating cycles
What is TSM-127-02-H-DH-A-K-TR used for?
The TSM-127-02-H-DH-A-K-TR is used in embedded computing modules, FPGA evaluation boards, and test and measurement equipment where 108 signals must be distributed across a dual-row 0.100 inch pitch SMT interface with polarized, error-proof mating. Its high-profile dual-height design accommodates stacked PCB configurations where daughter cards need mechanical clearance above the main board. The tape-and-reel packaging supports high-volume automated assembly lines producing communication hardware, industrial controllers, and data acquisition systems requiring reliable high-density interconnection.

Frequently Asked Questions
How many total contacts does the TSM-127-02-H-DH-A-K-TR provide and what is its connector pitch?
The TSM-127-02-H-DH-A-K-TR is a 54-position dual-row strip with a 0.100 inch (2.54 mm) pitch, giving it 108 total contacts arranged in 2 rows of 54 positions. This high contact count at the industry-standard 0.100 inch pitch makes it suitable for FPGA I/O distribution, multi-channel signal buses, and high-density board-to-board interconnects where a single connector must handle over 100 independent signal or power lines.
What does the polarizing key (K) option add to the TSM-127-02-H-DH-A-K-TR and why is it important for 108-pin connectors?
The polarizing key (K) feature adds a mechanical asymmetry to the connector body that physically prevents it from mating in the wrong orientation. With 108 contacts on a dual-row 0.100 inch pitch strip, an incorrect insertion could short or reverse-bias dozens of signal lines simultaneously, causing board damage or device failure. The K key eliminates this risk in production assembly and field service, reducing the cost of mismate events on high-value FPGA, processor, or test boards where a single connector error can destroy expensive components.
Is the TSM-127-02-H-DH-A-K-TR compatible with standard SAMTEC mating receptacles and what stacking height does it support?
Yes, the TSM-127-02-H-DH-A-K-TR mates with SAMTEC SSW and SSM series dual-row receptacles designed for 0.100 inch (2.54 mm) pitch in 54-position dual-row configurations. The high-profile dual-height (H-DH) stack variant supports board separation heights typically ranging from 8.51 mm to 20 mm or more, accommodating PCB-to-PCB stacking in embedded systems where components on the lower board require clearance below the upper daughter card mated at the 108-pin interface.
