Key Features
- 58 positions dual-row surface-mount terminal strip with 0.100" (2.54 mm) pitch grid
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place SMT placement
- Polarization (-P) feature prevents incorrect mating orientation during board assembly
- Dual-row (DH) layout reduces connector body length to approximately 29 positions per row
- Surface-mount solder attachment compatible with lead-free reflow profiles up to 260°C
Applications
The TSM-129-02-S-DH-A-P-TR is deployed in embedded single-board computers, industrial control modules, and test-and-measurement backplanes requiring 58 SMT signal lines on a standard 0.100" grid. The polarization key prevents mis-insertion during field assembly or board-level test, making it suitable for removable module interfaces where incorrect mating could damage sensitive circuits.

Frequently Asked Questions
What does the -P suffix indicate on TSM-129-02-S-DH-A-P-TR, and how does it protect a design during field assembly?
The -P suffix denotes a polarization or keying feature added to the connector body. This prevents reverse or offset mating with the corresponding socket, protecting 58-pin signal lines from short circuits or damage during field installation. It is especially valuable on boards with adjacent connectors of the same pitch where an operator might otherwise insert a module into the wrong 0.100" header by mistake.
How does the 58-position dual-row format of TSM-129-02-S-DH-A-P-TR compare in footprint to a single-row 58-pin connector on a PCB?
A dual-row layout at 0.100" pitch arranges 58 contacts into two 29-pin rows, making the connector body approximately 2.8 inches long. A single-row 58-pin header at the same pitch would need about 5.7 inches, so the dual-row format saves roughly 2.9 inches of PCB edge length, freeing board area for other components or traces.
Does the tape-and-reel format of TSM-129-02-S-DH-A-P-TR support standard 12 mm or 16 mm SMT feeder widths commonly used in assembly lines?
SAMTEC's TSM series tape-and-reel connectors are packaged in carrier tape conforming to EIA-481 standards, typically using feeder widths compatible with 12 mm to 24 mm SMT feeders depending on connector body size. Designers should confirm the exact reel specification with SAMTEC's product drawing, but the TR suffix guarantees compatibility with automated placement machines for high-volume runs without manual handling of individual parts.
