What are the key features of TSM-134-04-LM-DH-A-K-TR?
- 68-position dual-row (DH) configuration on 0.100" (2.54 mm) pitch for high-density board-to-board signal routing
- Right-angle (-A) termination enabling horizontal board-edge mating for reduced vertical stack height
- Keying (-K) feature preventing mis-mating between adjacent identical connectors on the same PCB
- Low-mount (-LM) profile minimizing connector height above PCB for compact enclosure designs
- Tape-and-reel (-TR) packaging supporting automated high-volume SMT pick-and-place assembly
- Gold-plated contacts delivering consistent low contact resistance and long mating cycle durability
What is TSM-134-04-LM-DH-A-K-TR used for?
TSM-134-04-LM-DH-A-K-TR is deployed in backplane systems, FPGA evaluation boards, and industrial motion controllers where 68 positions of keyed, right-angle, 0.100" pitch dual-row connectivity prevent installation errors and support high-signal-count PCB edge interfaces. The low-mount keyed design also suits modular medical instruments and rackmount computing platforms where connector polarity assurance is critical to avoid damage from incorrect mating.

Frequently Asked Questions
What does the -K keying suffix on TSM-134-04-LM-DH-A-K-TR prevent during PCB assembly and field service?
The -K keying feature on TSM-134-04-LM-DH-A-K-TR adds a mechanical polarization key to the 68-position dual-row connector body, preventing incorrect mating with adjacent identical connectors on the same PCB and eliminating reverse-insertion damage during field service on 0.100" pitch dual-row interfaces.
How many signal pins does TSM-134-04-LM-DH-A-K-TR offer, and what is the pin-per-row count?
TSM-134-04-LM-DH-A-K-TR provides 68 total positions in a dual-row (DH) layout, yielding 34 pins per row on a 0.100" (2.54 mm) pitch, making it one of the highest pin-count TSM terminal strips available for board-edge interconnect applications.
In which temperature environments can TSM-134-04-LM-DH-A-K-TR operate reliably without derating?
SAMTEC TSM series connectors are rated from -55°C to +125°C continuous operating temperature, making TSM-134-04-LM-DH-A-K-TR suitable for industrial automation, outdoor telecom enclosures, and avionics ground support equipment requiring a 68-pin connector to perform reliably across extreme thermal cycles.
When sourcing TSM-134-04-LM-DH-A-K-TR in volume, what packaging option reduces assembly line changeover time?
The -TR tape-and-reel suffix on TSM-134-04-LM-DH-A-K-TR provides reel-packaged 68-position connectors ready for automated SMT pick-and-place, reducing manual handling steps, minimizing feeder changeover time on assembly lines, and supporting continuous production runs at quantities of hundreds to thousands of units.
How does the low-mount (-LM) profile of TSM-134-04-LM-DH-A-K-TR benefit slim rackmount enclosure designs?
The -LM (low-mount) variant reduces the connector body height above the PCB surface by approximately 2 mm to 3 mm compared to standard TSM heights, enabling TSM-134-04-LM-DH-A-K-TR to fit within 1U and 2U rackmount chassis constraints while maintaining the full 68-pin dual-row signal capacity.
