What are the key features of TSM-134-02-FM-DH-A-K-TR?
- 68 positions in dual-row configuration at 0.100 inch (2.54 mm) pitch for maximum signal density
- Flat mount (FM) termination style for flush low-profile SMT board installation
- Keyed (K) polarization prevents incorrect mating orientation on 68-position interface
- Tape-and-reel (TR) packaging for high-volume automated pick-and-place assembly
- Dual-row DH format with A-coded alignment for reliable card-to-card mating
- Standard 0.100 inch pitch ensures broad compatibility with PCB routing tools and footprint libraries
What is TSM-134-02-FM-DH-A-K-TR used for?
The TSM-134-02-FM-DH-A-K-TR is well suited for high pin count board-to-board interconnect in server backplanes, FPGA expansion modules, industrial automation controllers, and communications rack equipment requiring 68 signals on a 0.100 inch pitch dual-row header. Its flat mount termination style minimizes connector height above the PCB surface, benefiting designs with tight mechanical clearances. Tape-and-reel packaging supports automated SMT manufacturing for volume production runs.

Frequently Asked Questions
What does the FM (flat mount) termination style mean for the TSM-134-02-FM-DH-A-K-TR PCB footprint?
The FM flat mount termination style means the TSM-134-02-FM-DH-A-K-TR contact tails lie flat along the PCB surface rather than extending through the board, reducing the required keep-out zone below the PCB to zero and enabling tight board stack heights on 0.100 inch pitch dual-row layouts.
How many signal positions does the TSM-134-02-FM-DH-A-K-TR provide per row?
The TSM-134-02-FM-DH-A-K-TR provides 68 total positions arranged in 2 rows of 34 contacts each on a 0.100 inch (2.54 mm) pitch, giving system designers 34 signals per row across the dual-row DH configuration.
For a server backplane design requiring 68 signals, when would this connector be preferred over a higher-density 0.050 inch pitch alternative?
The 0.100 inch pitch TSM-134-02-FM-DH-A-K-TR is preferred when PCB traces on the backplane must be routed at standard 0.100 inch grid spacings, when mating headers already use 0.100 inch pitch, or when the assembly team requires standard SMT tooling rather than fine-pitch placement equipment for 68-position connectors.
Does the K keying feature on TSM-134-02-FM-DH-A-K-TR matter when only one connector type is used per board?
Even with a single 68-position connector per board, the K keying feature prevents a 180-degree reversed mating, which would short all 68 pins in the wrong sequence, potentially damaging FPGAs, processors, or power rails connected to the dual-row header.
