Key Features
- 68-position dual-row configuration with 0.100" (2.54 mm) pitch supports wide parallel bus routing on compact PCBs
- FM (flash gold on mating area) contact finish ensures reliable low-resistance connections across many mating cycles
- Tape-and-reel (TR) format optimized for high-speed automated SMT pick-and-place assembly
Applications
The TSM-134-03-FM-DH-A-K-TR serves backplane and board-to-board interconnect applications in industrial control systems, test equipment, and communications hardware. The 68-position layout handles parallel data buses up to 64 bits wide plus control signals in a single connector. The FM (flash gold) contact finish reduces contact resistance, making this connector suitable for high-frequency digital signals and low-level analog interfaces.

Frequently Asked Questions
What contact finish does TSM-134-03-FM-DH-A-K-TR use, and why is it preferred for certain signal interfaces?
The TSM-134-03-FM-DH-A-K-TR uses FM (flash gold) contact finish, which deposits a thin gold layer over the mating surface. Gold provides a contact resistance typically below 20 mΩ and prevents oxidation, making it ideal for low-level analog signals and high-speed digital interfaces where stable, low-resistance contacts are required over many thousands of mating cycles.
How many signal lines can be routed through the TSM-134-03-FM-DH-A-K-TR in a 64-bit bus architecture?
The TSM-134-03-FM-DH-A-K-TR provides 68 positions in a dual-row layout, allowing a 64-bit data bus plus 4 additional lines for address, control, or power signals. At 0.100" pitch with 34 contacts per row, the connector fits standard 2.54 mm dual-row PCB pads and mates with compatible headers in backplane or daughter card designs.
How does TSM-134-03-FM-DH-A-K-TR differ from the TSM-134-03-SS-DH-A-K-TR in terms of contact material?
TSM-134-03-FM-DH-A-K-TR uses a flash gold (FM) contact finish applied over a base metal, while the SS variant uses stainless steel contacts. Flash gold provides lower contact resistance (typically below 20 mΩ) and better performance for sensitive analog and digital signals, whereas stainless steel contacts offer superior corrosion resistance in harsh environments at the cost of slightly higher contact resistance.
Is tape-and-reel packaging of TSM-134-03-FM-DH-A-K-TR compatible with standard SMT assembly equipment?
Yes, the TSM-134-03-FM-DH-A-K-TR tape-and-reel (TR) packaging is compatible with standard SMT pick-and-place machines using 12 mm or wider feeders. The embossed carrier tape maintains consistent part orientation at the 0.100" pitch, ensuring accurate automated placement on PCB pads and enabling high-throughput production on standard reflow soldering lines.
