What are the key features of TSM-133-01-STL-DH-A-K-TR?
- 66-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch for high pin-count board-to-board interconnects
- STL (short top-load) mating style allowing low-profile stacking with reduced connector body height above the PCB
- K keying feature preventing incorrect insertion orientation, safeguarding all 66 signal channels against assembly errors
- Tape-and-reel (TR) format enabling automated pick-and-place surface mount assembly at high production volumes
What is TSM-133-01-STL-DH-A-K-TR used for?
The TSM-133-01-STL-DH-A-K-TR is designed for space-efficient high pin-count mezzanine and daughter card interfaces in industrial computing, FPGA platforms, and test equipment. Its 66-position dual-row layout at 0.100" pitch and short top-load profile enable compact stacked board assemblies in 1U rack systems and embedded modules with limited vertical clearance. The keyed and tape-and-reel format ensures reliable high-volume automated assembly and field-replaceable module designs.

Frequently Asked Questions
How does the STL (short top-load) designation affect connector height and mating on this 66-pin strip?
STL designates a short top-load style where the mating connector inserts from above with a reduced body profile, typically 3 mm to 5 mm shorter than standard top-load variants. On a 66-position dual-row connector at 0.100" pitch, this allows the mated board pair to achieve a lower overall stack height, which is essential in 1U rack enclosures and compact embedded platforms.
When would a designer choose TSM-133-01-STL-DH-A-K-TR over TSM-133-01-TM-DH-A-K-TR?
The STL variant is preferred over the TM (top-mount) style when PCB height clearance between stacked boards is constrained and a low-profile mating interface is needed without sacrificing all 66 signal channels. If the design requires 8 mm or less of vertical board separation on a 0.100" pitch 66-pin interface, the short top-load geometry of the STL version provides that clearance reduction compared to standard-height TM alternatives.
Is the TSM-133-01-STL-DH-A-K-TR suitable for high-speed digital signals or primarily for low-frequency use?
At 0.100" (2.54 mm) pitch, this connector series is optimized for mixed signal and power routing rather than differential high-speed channels above 500 MHz. For signals below 200 MHz, the TSM-133-01-STL-DH-A-K-TR provides adequate impedance and crosstalk performance across its 66 pins. Designers targeting multi-gigabit interfaces should instead evaluate SAMTEC's high-speed mezzanine series with controlled-impedance contacts.
