Key Features
- 29-position dual-row 0.100" pitch surface mount terminal strip with shrouded housing for guided mating and mismatch prevention
- Single-row vertical SMT footprint with tape-and-reel packaging for automated pick-and-place assembly in production lines
- Short-tail (STL) contact variant providing optimized solder joint geometry for improved coplanarity on surface mount boards
Applications
The TSM-129-05-STL-SH-P-TR is suited for surface mount board-to-board or board-to-cable interconnects in embedded systems, industrial controllers, and test equipment requiring 29 positions at 0.100" pitch. The shrouded housing guides mating connectors into correct alignment, reducing assembly errors in dense wiring environments, while the tape-and-reel format enables efficient automated SMT placement.

Frequently Asked Questions
How does the short-tail (STL) contact variant of the TSM-129-05-STL-SH-P-TR improve surface mount solder joint quality compared to standard-tail versions?
The shorter contact tail on the STL variant reduces the distance between the contact body and the PCB pad, improving coplanarity across all 29 positions. Better coplanarity means more uniform solder paste coverage during reflow, which reduces open-joint defects in automated SMT assembly. For boards processed at 250°C reflow temperatures with standard no-clean paste, this translates to higher first-pass yield.
For a motor control unit with 29 I/O signals, what benefit does the shrouded housing of the TSM-129-05-STL-SH-P-TR provide during field wiring?
The shroud mechanically constrains the mating cable connector to a single correct orientation, preventing a technician from inserting the cable connector offset by 1 or 2 positions — a risk that could cross 29 signals and damage the motor drive circuitry. This keying feature is especially valuable in field installations where vibration, dim lighting, or tight enclosures make careful alignment difficult.
When is TSM-129-05-STL-SH-P-TR a better procurement choice than the TSM-129-05-TL-SH-P-TR for a new SMT production line?
The STL variant's shorter solder tail is preferable when PCB thickness is below 1.6 mm or when the reflow oven profile is optimized for fine-pitch SMT components, since the reduced tail length minimizes thermal mass at the joint and keeps the contact tip within the solder paste deposit zone across all 29 positions. The TL variant suits thicker boards where a longer tail improves mechanical anchor strength.
