Key Features
- 72-position dual-row SMT terminal strip with 0.100" (2.54 mm) pitch for high-density board interconnects
- Gold-plated contacts providing low contact resistance and superior corrosion resistance
- 4.0 mm tail length variant (TL) enabling through-hole soldering for added mechanical retention
- Designed for right-angle or vertical board-to-board and wire-to-board assembly applications
Applications
The TSM-136-04-TL-DH-A-K-TR is well suited for backplane and daughtercard assemblies requiring dense 72-position dual-row connectivity at a 0.100" pitch. Its surface-mount footprint with through-hole tails makes it ideal for industrial control systems, test and measurement boards, and embedded computing modules where secure mechanical attachment and signal integrity are critical.

Frequently Asked Questions
What is the pitch and pin count of the TSM-136-04-TL-DH-A-K-TR?
The TSM-136-04-TL-DH-A-K-TR features a 0.100" (2.54 mm) pitch with 72 positions arranged in a dual-row (2×36) configuration. This high pin-count layout supports dense signal routing on compact PCBs requiring more than 36 individual connections per connector.
Which PCB assembly scenarios benefit from the through-hole tail length of this terminal strip?
With its 4.0 mm through-hole tail variant, the TSM-136-04-TL-DH-A-K-TR provides mechanical anchoring during wave or selective soldering, making it ideal for industrial and rugged environments where vibration could compromise purely SMT-soldered connectors over time.
How does the 72-position dual-row format compare to a single-row alternative for backplane designs?
A 72-position dual-row (2×36) strip occupies roughly half the board edge length compared to a 72-pin single-row connector at the same 0.100" pitch, saving approximately 47.5 mm of PCB length and enabling more compact backplane layouts in 19-inch rack systems or embedded chassis.
What contact plating is used and how does it affect mating reliability?
The TSM-136-04-TL-DH-A-K-TR uses gold-plated contacts, which deliver contact resistance below 20 mΩ and withstand at least 100 mating cycles while resisting oxidation in humid or industrial environments, ensuring long-term signal reliability across all 72 positions.
