What are the key features of TSM-129-04-TL-DH-A-K-TR?
- 58-position dual-row layout at 0.100 inch (2.54 mm) pitch for high-density signal routing
- Shrouded latching and keyed (K) design preventing misalignment and accidental unmating
- Surface-mount termination for automated SMT reflow assembly on multilayer PCBs
- Tape-and-reel (TR) packaging enabling high-volume pick-and-place production
- Dual-row construction routing 58 signals in roughly half the board-edge length of single-row alternatives
What is TSM-129-04-TL-DH-A-K-TR used for?
The TSM-129-04-TL-DH-A-K-TR is used in high-pin-count board-to-board and board-to-cable assemblies for industrial automation, FPGA carrier boards, and multi-channel data-acquisition platforms requiring secure, keyed connectors. Its 58-position keyed and latching design reduces field assembly errors in systems where accidental mismating of a 58-pin connector could damage signal lines or power rails.

Frequently Asked Questions
What does the K suffix indicate on the TSM-129-04-TL-DH-A-K-TR connector, and why does it matter in assembly?
The K suffix designates a keyed housing that physically prevents incorrect mating orientation on the 58-pin, 0.100 inch pitch connector. Keying is critical in dense 58-position assemblies where reverse mating could short power and signal pins, potentially damaging expensive FPGA modules, DSP boards, or industrial control circuitry.
How many signals does the TSM-129-04-TL-DH-A-K-TR route, and what pitch does it use?
The TSM-129-04-TL-DH-A-K-TR routes 58 signals in a dual-row surface-mount configuration at a standard 0.100 inch (2.54 mm) pitch. With 29 contacts per row, it supports high-density wiring of analog, digital, power, and ground signals across a single compact SMT connector footprint.
Is the TSM-129-04-TL-DH-A-K-TR suitable for high-volume automated production?
Yes, the TR suffix confirms tape-and-reel delivery, which feeds directly into automated pick-and-place equipment for SMT reflow assembly. Manufacturing lines can place the 58-pin connector at standard machine rates, maintaining consistent orientation and solder joint quality across thousands of units in a single production run.
When should a designer choose the TSM-129-04-TL-DH-A-K-TR over a 56-position alternative like TSM-128 series?
Engineers choose the 58-position TSM-129-04-TL-DH-A-K-TR over a 56-pin variant when the design requires 2 additional signal or power pins within the same 0.100 inch dual-row footprint. The extra 2 contacts at 2.54 mm pitch can accommodate dedicated power-good, enable, or status lines without adding a secondary connector to the PCB.
