What are the key features of TSM-129-04-FM-DH-A-K-TR?
- 58-position dual-row configuration at 0.100" (2.54 mm) industry-standard pitch
- Female mating (FM) with integrated polarization key (K) for foolproof board-to-board mating
- Right-angle (A) orientation enabling horizontal signal routing on PCB edge
- Surface mount termination compatible with standard SMT reflow processes
- Tape-and-reel (TR) packaging for high-volume automated pick-and-place production
What is TSM-129-04-FM-DH-A-K-TR used for?
The TSM-129-04-FM-DH-A-K-TR suits backplane and daughtercard interconnects where a 58-position right-angle female header is needed to connect boards at a 90-degree angle, such as in VME, PCIe card cages, and industrial PLC I/O racks. The integrated polarization key prevents misalignment during assembly, making it reliable for production environments where manual mating by field technicians must be foolproofed.

Frequently Asked Questions
What orientation does the TSM-129-04-FM-DH-A-K-TR provide, and how does it affect PCB layout?
The A suffix designates a right-angle orientation, meaning the 58-position dual-row connector mounts on the PCB surface while the mating direction is parallel to the board plane. This allows signals to enter horizontally from a daughtercard or backplane, saving vertical board height compared to vertical (straight) mount alternatives at the same 2.54 mm pitch.
Does the TSM-129-04-FM-DH-A-K-TR include a polarization key to prevent incorrect mating?
Yes, the K suffix indicates that this connector includes a physical polarization key. The key mechanically prevents misoriented insertion, ensuring the 58-pin interface always connects in the correct polarity. This feature is particularly valuable in field-serviceable equipment where an inexperienced technician must mate the connector without visual pin-1 reference markings.
What alternative part should I use when I need the same 58-position count without the right-angle orientation?
For the same 58-position dual-row count in a vertical (straight) surface mount orientation, evaluate the TSM-129-01 base series from SAMTEC, which shares the 0.100 inch (2.54 mm) pitch and the same dual-row DH housing. The pinout and mating headers remain identical, so switching between right-angle and vertical mount typically only requires a footprint rotation change on the PCB layout.
