What are the key features of TSM-134-04-SM-DH-A-K-TR?
- 68-position dual-row SMT terminal strip at 0.100" pitch delivers 34 contacts per row for very high signal count board interconnect
- Alignment key (K suffix) prevents incorrect mating orientation, protecting all 68 contacts in critical signal and power routing applications
- Tape-and-reel (TR) packaging with SMT mounting enables direct integration into automated pick-and-place assembly for high-volume production
What is TSM-134-04-SM-DH-A-K-TR used for?
The TSM-134-04-SM-DH-A-K-TR is used in high-density module-to-backplane and mezzanine card interconnect designs in server, networking, and industrial automation equipment requiring 68 simultaneous signals at 0.100-inch pitch. The alignment key ensures single-orientation mating, protecting the interface in field-replaceable module architectures where accidental connector reversal could damage the host board. Tape-and-reel delivery streamlines high-volume automated SMT assembly in demanding production environments.

Frequently Asked Questions
What is the total position count and per-row arrangement of the TSM-134-04-SM-DH-A-K-TR?
The TSM-134-04-SM-DH-A-K-TR provides 68 positions in a dual-row layout with 34 contacts per row at 0.100-inch pitch, spanning approximately 3.4 inches in board length. This configuration is ideal for backplane-to-mezzanine interfaces in servers and networking line cards requiring simultaneous routing of data, power, and ground signals across a single connector body.
For a hot-swap mezzanine card design with 68 signals, how does the alignment key on the TSM-134-04-SM-DH-A-K-TR reduce risk?
The alignment key (K suffix) on the TSM-134-04-SM-DH-A-K-TR prevents insertion in the wrong orientation, which in a 68-position dual-row connector could simultaneously reverse up to 34 differential pairs or short power rails to signal pins. For hot-swap mezzanine cards cycled multiple times in production testing or field service, this mechanical safeguard eliminates a major cause of board damage and reduces rework costs on 0.100-inch pitch assemblies.
How does the TSM-134-04-SM-DH-A-K-TR compare to the TSM-136-03-S-DH-A-K-TR when selecting a high-density SMT connector for a new backplane design?
The TSM-134-04-SM-DH-A-K-TR offers 68 positions at 0.100-inch pitch, while the TSM-136-03-S-DH-A-K-TR provides 72 positions at the same pitch. Designs needing exactly 68 connections—such as 32 differential pairs plus 4 ground pins—should select the TSM-134-04-SM-DH-A-K-TR to avoid unused contacts that can complicate PCB routing. Both parts share tape-and-reel packaging and alignment key features, so the choice is driven purely by the required signal count.
