Key Features
- 68 positions in dual-row 0.100 inch pitch for high signal density in a compact SMT footprint
- FM floating mount feature accommodates PCB misalignment in demanding assembly environments
- Tape and reel (TR) packaging optimized for automated SMT pick-and-place production
- Gold-plated (K) contacts providing reliable low-resistance mating and corrosion resistance
- DH dual-row arrangement doubles pin count versus single-row connectors of the same board length
Applications
The TSM-134-04-FM-DH-A-K-TR is designed for high-density backplane interconnects, PCB-to-PCB signal interfaces, and modular board stacking systems where 68 signal pins must be accommodated in a minimal 0.100 inch pitch SMT footprint. Its floating mount feature makes it particularly suitable for applications subject to PCB warpage or mechanical tolerance variation during assembly.

Frequently Asked Questions
What does the FM floating mount feature of TSM-134-04-FM-DH-A-K-TR offer compared to a standard fixed-mount TSM connector?
The FM floating mount design in TSM-134-04-FM-DH-A-K-TR allows up to approximately 0.5 mm of lateral movement during mating, which compensates for PCB misalignment and board warpage common in large backplane assemblies. Fixed-mount connectors at 0.100 inch pitch do not provide this compliance, leading to higher stress on solder joints in misaligned board stacks.
How many signal pins does TSM-134-04-FM-DH-A-K-TR provide, and how does its dual-row DH layout compare to single-row connectors?
TSM-134-04-FM-DH-A-K-TR provides 68 pins in a dual-row DH arrangement at 0.100 inch (2.54 mm) pitch, delivering the same signal count as a single-row 68-pin connector but using approximately half the board length. This dual-row configuration is essential for high-density interface designs where linear PCB space is limited.
Does the gold plating on TSM-134-04-FM-DH-A-K-TR contacts improve long-term reliability in industrial or test equipment applications?
Yes, the K designation in TSM-134-04-FM-DH-A-K-TR indicates gold-plated contacts, which provide corrosion resistance and stable contact resistance over thousands of mating cycles. Gold plating is particularly valuable in test and measurement equipment, industrial instrumentation, and field-replaceable modules where connector reliability across repeated insertions is critical.
What production volume considerations make TSM-134-04-FM-DH-A-K-TR's tape-and-reel packaging advantageous for board-level assembly?
The TR (tape and reel) suffix of TSM-134-04-FM-DH-A-K-TR means the connector is supplied in continuous reel format compatible with automated SMT pick-and-place equipment. This packaging supports high-volume PCB assembly at rates exceeding thousands of boards per shift, reducing manual handling and placement errors compared to tray or tube packaging for a 68-pin SMT connector.
