What are the key features of TSM-127-04-FM-DH-A-K-TR?
- 54-position single-row layout at 0.100" (2.54 mm) pitch for standard-density board interconnects
- Flush-mount (FM) termination style for minimal PCB protrusion and improved board planarity
- Dual-height keyed shroud (DH-K) enforces correct connector polarity across all 54 positions
- Gold-plated contacts (A finish) provide low and stable contact resistance for reliable signal transmission
- Tape-and-reel (TR) packaging enables high-throughput automated SMT pick-and-place assembly
What is TSM-127-04-FM-DH-A-K-TR used for?
SAMTEC TSM-127-04-FM-DH-A-K-TR is ideal for slim-profile industrial controllers, medical devices, and compact embedded modules where a 54-position surface-mount connector must remain flush with the PCB surface. The keyed shroud and gold contacts provide reliable signal routing with polarization protection, making this part a strong choice for precision instruments with strict board-height and error-proofing requirements.

Frequently Asked Questions
How does the flush-mount termination on TSM-127-04-FM-DH-A-K-TR differ from standard SMT tails in low-profile designs?
The -FM suffix designates a flush-mount termination where solder tails are formed to sit flat against the PCB surface rather than extending below it. This reduces the overall connector protrusion on the 54-position layout, making TSM-127-04-FM-DH-A-K-TR suitable for slim enclosures with minimal clearance below the board.
In which medical or industrial applications is the keyed shroud on TSM-127-04-FM-DH-A-K-TR most critical?
The dual-height keyed shroud is most critical in applications such as medical monitoring equipment, industrial PLCs, and modular sensor boards where a reversed 54-pin connection could damage signal conditioning circuitry or cause safety-relevant faults. The -K polarization key ensures the connector seats correctly every time.
Does TSM-127-04-FM-DH-A-K-TR support lead-free reflow soldering for RoHS-compliant manufacturing?
Yes. SAMTEC TSM series connectors with gold contacts (A finish) and standard SMT terminations are compatible with RoHS-compliant lead-free reflow processes at temperatures up to 260 degrees C peak. Verify the specific reflow profile with SAMTEC's product specification sheet before production qualification.
What procurement considerations apply when ordering TSM-127-04-FM-DH-A-K-TR in tape-and-reel for a production ramp?
For a production ramp, buyers should confirm reel quantity and minimum order requirements with SAMTEC or an authorized distributor, as the 54-position TSM-127-04-FM-DH-A-K-TR in tape-and-reel (TR) format may carry a minimum reel quantity of 250 or 500 pieces depending on the product configuration.
