What are the key features of TSM-133-04-FM-DH-A-K-TR?
- 66-position dual-row .100" (2.54 mm) pitch surface mount terminal strip for high-density signal and power distribution on backplanes
- FM tail option provides formed right-angle or special tail geometry for routing flexibility in constrained PCB layouts
- K keying feature prevents misalignment during mating, reducing assembly errors in dual-row 2.54 mm pitch configurations
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for high-volume manufacturing
What is TSM-133-04-FM-DH-A-K-TR used for?
The TSM-133-04-FM-DH-A-K-TR is designed for high-density backplane interconnection, server motherboard edge connectors, and industrial controller bus interfaces where 66 positions and .100" pitch maximize signal count per unit board length. The dual-row layout and keying option ensure reliable mating orientation in rack-mount and modular instrumentation systems. Tape-and-reel packaging facilitates automated SMT assembly in telecommunications and computing hardware production.

Frequently Asked Questions
How many positions and rows does TSM-133-04-FM-DH-A-K-TR provide for backplane interconnection?
The TSM-133-04-FM-DH-A-K-TR provides 66 total positions in a dual-row (DH) arrangement with 33 pins per row at .100" (2.54 mm) pitch. This high-density layout supports bus interfaces and backplane signal distribution where maximizing pin count within a compact PCB footprint is essential for computing and industrial controller designs.
What does the FM tail suffix indicate on the TSM-133-04-FM-DH-A-K-TR?
The FM suffix on Samtec TSM series connectors designates a formed tail geometry that differs from standard straight through-hole tails. This formed tail supports specific routing or right-angle transitions on the PCB, making the TSM-133-04-FM-DH-A-K-TR adaptable to board layouts where vertical clearance is limited or signal traces must exit at an angle beneath the 66-position connector body.
How does the K keying option on TSM-133-04-FM-DH-A-K-TR prevent connector mating errors?
The K suffix adds a keying polarization feature that mechanically prevents the connector from mating in the wrong orientation, which is critical for 66-position dual-row connectors where reversing the mating pair would short all 66 signals. This reduces assembly risk in high-density backplane and server board applications, particularly during field maintenance when technicians replace modules under time pressure.
Is TSM-133-04-FM-DH-A-K-TR suitable for automated SMT assembly, and what packaging format does it use?
Yes, the TR suffix confirms tape-and-reel packaging, which is directly compatible with standard pick-and-place equipment used in SMT assembly lines. Each reel contains multiple units of the 66-position connector, enabling consistent placement at 2.54 mm pitch accuracy. This format is preferred for high-volume production in telecommunications, server hardware, and industrial electronics manufacturing.
