What are the key features of TSM-129-01-FM-DH-A-P-TR?
- 58 positions (29 per row) on 0.100" (2.54 mm) dual-row pitch for dense PCB signal interfaces
- Flush-mount (FM) insulator design minimizes connector height above the PCB surface
- Polarized (P) keying prevents incorrect mating on 58-pin interfaces
- Alignment peg (A) option for accurate mechanical registration during SMT reflow
- Tape and reel (TR) packaging supports automated SMT pick-and-place assembly
What is TSM-129-01-FM-DH-A-P-TR used for?
The TSM-129-01-FM-DH-A-P-TR is designed for high-density dual-row signal interconnects on embedded SBCs, FPGA carrier boards, and industrial I/O expansion modules where 58 positions on a 0.100" grid must be routed reliably. Its flush-mount insulator reduces the total PCB stack height, and the polarized keying feature ensures correct mating in field-replaceable module systems.

Frequently Asked Questions
How many positions does the TSM-129-01-FM-DH-A-P-TR provide, and how are they laid out on the PCB?
The connector provides 58 positions arranged in a dual-row (2 × 29) layout on a 0.100" (2.54 mm) pitch. This high position count in a single surface mount footprint supports routing of wide data buses, mixed signal lines, or power-plus-signal combinations in compact embedded system designs.
What does the flush-mount (FM) insulator designation mean for the TSM-129-01-FM-DH-A-P-TR, and when should engineers choose it over a standard-height variant?
The FM (flush-mount) insulator sits at a lower profile height above the PCB than standard or high-profile variants, reducing the gap between the board surface and the connector body. Engineers select the FM version in multi-board assemblies or slim enclosures where the 58-pin connector must not exceed a specific height limit to allow proper PCB-to-PCB clearance.
How does the polarization keying feature protect a 58-pin interface from mating errors during field installation?
The P (polarized) keying introduces a mechanical asymmetry that physically prevents the mating receptacle from being inserted 180° inverted. On a 58-pin dual-row interface, an inverted mating would reverse all signal assignments, potentially connecting supply rails to ground or applying logic signals to output pins, causing immediate circuit damage across 29 signal lines per row.
What is the purpose of the alignment peg (A) on the TSM-129-01-FM-DH-A-P-TR during PCB assembly?
The alignment peg registers the connector body into matching holes in the PCB before reflow soldering, preventing lateral movement caused by paste surface tension during the reflow oven cycle. For a 58-pin connector spanning approximately 1.4 inches of PCB length, peg alignment ensures all 58 contact pads remain correctly positioned over their corresponding PCB pads.
