What are the key features of TSM-129-04-L-DH-A-K-TR?
- 58-position dual-row right-angle (L) surface-mount design on 2.54 mm (0.100") pitch for edge-accessible board interconnects
- Keyed (K suffix) mechanical alignment ensuring correct mating in assemblies with multiple adjacent connectors
- Gold-plated contacts delivering low contact resistance and corrosion resistance across all 58 positions
- Tape-and-reel (TR) packaging supporting high-volume automated SMT assembly with pick-and-place compatibility
What is TSM-129-04-L-DH-A-K-TR used for?
The TSM-129-04-L-DH-A-K-TR is suited for edge-accessible board interconnects in industrial controllers, embedded systems, and server expansion cards where a right-angle 58-position header allows mating connectors to be accessed from the board's side edge rather than the top surface. This orientation is valuable in tight board stacks where vertical clearance is limited but horizontal access is available. Its tape-and-reel packaging ensures production-ready automated assembly integration.

Frequently Asked Questions
What does the L suffix in TSM-129-04-L-DH-A-K-TR indicate, and when is a right-angle connector preferred over a vertical one?
The L suffix designates a right-angle (horizontal) connector orientation, meaning the mating direction is parallel to the PCB surface rather than perpendicular. Right-angle connectors are preferred when board stacking limits vertical clearance but provides horizontal access from the PCB edge, a common scenario in layered backplane assemblies or panel-mounted circuit boards.
How many signal positions does TSM-129-04-L-DH-A-K-TR provide, and how are they distributed across the two rows?
The TSM-129-04-L-DH-A-K-TR provides 58 positions arranged in a dual-row configuration, with 29 pins per row on a 2.54 mm (0.100") pitch. This dual-row right-angle layout carries 58 signals while maintaining a board footprint compatible with standard 0.100" mating connectors from the same connector family.
For an embedded system enclosure with side panel access, how does TSM-129-04-L-DH-A-K-TR's right-angle design simplify cabling?
In enclosures where cabling enters from the side rather than the top, the right-angle orientation of TSM-129-04-L-DH-A-K-TR allows the mating connector's cable to run parallel to the PCB plane without sharp cable bends. This reduces mechanical stress on the cable assembly and provides a cleaner internal wiring layout for all 58 signals compared to a vertical header with a sharp 90-degree cable turn.
Does TSM-129-04-L-DH-A-K-TR support automated SMT assembly, and how is it shipped?
Yes, the TR suffix means TSM-129-04-L-DH-A-K-TR is packaged in tape-and-reel format, compatible with automated SMT pick-and-place machines used in volume PCB manufacturing. This ensures the connector is delivered in the correct orientation for each placement cycle and is suitable for high-throughput production lines assembling hundreds or thousands of boards.
