What are the key features of TSM-128-03-FM-DH-A-K-TR?
- 56-position dual-row terminal strip on 0.100" (2.54 mm) pitch for high-density connectivity
- Full mechanical shroud (FM) protects male contacts and guides mating connector alignment
- Right-angle (A) mounting orientation for PCB edge connections in rack and chassis assemblies
- Polarizing key (K) prevents reverse insertion and mis-mating in dual-row configurations
- Tape-and-reel (TR) packaging for automated SMT pick-and-place production compatibility
What is TSM-128-03-FM-DH-A-K-TR used for?
The TSM-128-03-FM-DH-A-K-TR is designed for high-pin-count PCB edge interconnects in backplane systems, industrial control modules, and communications equipment. The full mechanical shroud and polarizing key ensure error-free mating in field-replaceable assemblies with 56 contact positions at 2.54 mm pitch. Right-angle orientation minimizes vertical board height while maintaining reliable signal and power routing at the PCB edge.

Frequently Asked Questions
What is the pin count and contact pitch on TSM-128-03-FM-DH-A-K-TR?
The TSM-128-03-FM-DH-A-K-TR provides 56 contact positions in a dual-row layout with a 0.100 inch (2.54 mm) pitch. This is one of the most common backplane pitches, making it compatible with a wide range of standard mating receptacles and widely available on authorized Samtec distributor shelves.
How does the full mechanical shroud benefit engineers designing PCBs with TSM-128-03-FM-DH-A-K-TR?
The full mechanical shroud surrounding all 56 pins protects contacts from bending during PCB handling, transportation, and field installation. It also provides a positive registration surface that guides the mating connector into place, reducing alignment errors and contact wear over repeated insertion cycles in backplane or modular system designs.
Why use a right-angle connector like TSM-128-03-FM-DH-A-K-TR instead of a vertical orientation?
The right-angle (A) mounting routes the 56 contact positions out the side of the PCB rather than upward, which reduces the required connector height above the board and allows board-edge mating with a daughter card or cable assembly. This orientation is preferred in rack-mount chassis designs where clearance between boards is limited to 10 to 25 mm.
What packaging does TSM-128-03-FM-DH-A-K-TR come in for volume procurement?
TSM-128-03-FM-DH-A-K-TR is available in tape-and-reel (TR) packaging, which is ideal for automated pick-and-place SMT assembly. Buyers procuring for production volumes should verify reel quantities and lead times with authorized Samtec distributors, as 56-position right-angle shrouded connectors may be available in standard reel counts to minimize per-unit cost.
