What are the key features of TSM-127-03-FM-DH-A-K-TR?
- 54-position dual-row terminal strip with 0.100" (2.54 mm) contact pitch
- Right-angle (A) orientation for PCB edge mounting and reduced vertical profile
- Full mechanical shroud (FM) protects contacts and provides mating guidance
- Polarizing key (K) prevents mis-mating and ensures correct connector orientation
- Tape-and-reel (TR) packaging for high-volume automated pick-and-place assembly
What is TSM-127-03-FM-DH-A-K-TR used for?
The TSM-127-03-FM-DH-A-K-TR is used in industrial control systems, backplane assemblies, and communications equipment where a 54-position dual-row edge connector with a protective shroud is required. The right-angle orientation allows board-edge mating in rack-mount or chassis applications, while the polarizing key prevents assembly errors. Tape-and-reel packaging supports efficient high-volume SMT production.

Frequently Asked Questions
How many contact positions does TSM-127-03-FM-DH-A-K-TR provide and at what pitch?
The TSM-127-03-FM-DH-A-K-TR provides 54 contact positions in a dual-row arrangement with a standard 0.100 inch (2.54 mm) pitch. This configuration supports high pin-count PCB interconnects in industrial backplane, control system, and communications equipment applications.
What role does the full mechanical shroud (FM) play in TSM-127-03-FM-DH-A-K-TR connector performance?
The full mechanical shroud protects the 54 male pins from mechanical damage during handling and provides guided mating to reduce the risk of bent contacts. This shroud design also adds lateral rigidity to the connector on the PCB, which is important in right-angle configurations exposed to vibration or repeated mating cycles.
Can TSM-127-03-FM-DH-A-K-TR be used in an automated SMT production line?
Yes, the tape-and-reel (TR) suffix confirms that TSM-127-03-FM-DH-A-K-TR is packaged for automated pick-and-place assembly. The 0.100 inch pitch and SMT termination are compatible with standard reflow solder processes, making it practical for high-volume manufacturing lines producing boards with 54-pin dual-row edge connectors.
What are the lifecycle and procurement considerations when sourcing TSM-127-03-FM-DH-A-K-TR for a long-term production program?
Buyers should confirm active lifecycle status and check authorized Samtec distributor lead times, as right-angle terminal strips with 54 positions and full shrouds may have longer lead times than standard parts. Ordering in tape-and-reel reels of 250 or 500 units is common for sustained production volumes, and design engineers should verify RoHS compliance before committing to a BOM.
