What are the key features of TSM-131-04-L-DH-A-K-TR?
- 62-position dual-row configuration on 2.54 mm pitch delivers high signal density for complex board-to-board interfaces
- Long (L) tail variant provides deeper PCB engagement for superior mechanical retention in vibration-prone environments
- Dual-height (DH) body allows mated PCB pairs to clear tall components up to 8.51 mm between boards
- Tape-and-reel (TR) packaging supports uninterrupted high-volume automated SMT pick-and-place assembly
What is TSM-131-04-L-DH-A-K-TR used for?
The TSM-131-04-L-DH-A-K-TR is deployed in high-channel-count board-to-board interconnects for embedded computing backplanes, data acquisition systems, and industrial automation controllers requiring 62 signal paths on a standard 2.54 mm pitch. Its long tail and dual-height body combination suits stacked PCB architectures where mechanical robustness and inter-board clearance are both critical. The tape-and-reel format ensures this connector integrates seamlessly into automated SMT production lines for cost-effective high-volume manufacturing.

Frequently Asked Questions
How many signal positions does TSM-131-04-L-DH-A-K-TR provide, and what pitch is used?
The TSM-131-04-L-DH-A-K-TR provides 62 total positions arranged in 2 rows of 31 contacts each on a 2.54 mm (0.100 inch) pitch. This allows routing of up to 62 independent signals or 31 differential pairs across a single connector footprint, making it practical for high-channel data acquisition boards and embedded processor expansion cards.
When should a designer choose the long-tail (L) variant over a standard-tail TSM connector?
Long tails provide additional solder joint height, typically increasing the standoff to approximately 3.05 mm versus 1.65 mm for standard tails, which improves resistance to solder joint cracking under thermal cycling or mechanical flex. The long-tail TSM-131-04-L-DH-A-K-TR is preferred in industrial environments where PCBs experience temperature swings from -40 °C to +85 °C or repeated vibration that would fatigue shorter solder joints.
What inter-board clearance does the dual-height body of TSM-131-04-L-DH-A-K-TR provide for stacked PCB designs?
The dual-height (DH) body raises the mated connector stack height to approximately 8.51 mm above the lower PCB surface, providing sufficient vertical clearance to accommodate SMD capacitors, small ICs, and low-profile inductors placed between the two boards. This clearance figure is critical during PCB layout review to prevent component-to-board collisions in tightly stacked embedded module designs.
How does TSM-131-04-L-DH-A-K-TR compare to a 50-position TSM variant for backplane expansion designs?
The TSM-131-04-L-DH-A-K-TR adds 12 extra positions over a 50-position variant within the same 2.54 mm pitch family, extending the body by approximately 30.5 mm. For backplane expansions requiring more than 50 signals, the 62-position version eliminates the need for a second connector, reducing BOM complexity, solder joint count, and PCB routing congestion on high-density industrial backplanes.
