Key Features
- 56-position dual-row surface mount terminal strip with 0.100" (2.54 mm) pitch for high-density board-to-board connections
- Gold-plated (Au) contacts on pin field provide low contact resistance and corrosion resistance in demanding environments
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly, reducing manufacturing time and improving placement accuracy
- Dual-row (DH) design maximizes signal density while minimizing PCB footprint compared to single-row connectors
Applications
The TSM-128-04-F-DH-A-K-TR is well suited for high-density digital interface boards, backplane interconnects, and embedded computing modules where 56-position surface mount connectivity is required. Its dual-row 0.100" pitch layout is commonly used in industrial controllers, telecommunications equipment, and test-and-measurement instrumentation. The tape-and-reel format supports high-volume automated PCB assembly lines requiring consistent, repeatable connector placement.

Frequently Asked Questions
What is the pitch and row configuration of the TSM-128-04-F-DH-A-K-TR?
The TSM-128-04-F-DH-A-K-TR uses a 0.100" (2.54 mm) pitch dual-row (DH) surface mount configuration with 56 total positions, providing 28 positions per row for high-density PCB connections in compact board designs.
How does the gold-plated contact finish on TSM-128-04-F-DH-A-K-TR benefit long-term reliability?
The gold (Au) plated contacts on the TSM-128-04-F-DH-A-K-TR deliver contact resistance typically below 20 mΩ and resist oxidation in humid or corrosive environments, making this connector suitable for mission-critical industrial or telecom applications requiring 1000+ mating cycles.
Which assembly processes are compatible with the TSM-128-04-F-DH-A-K-TR tape-and-reel packaging?
The TSM-128-04-F-DH-A-K-TR ships in tape-and-reel (TR) format, compatible with standard SMT pick-and-place machines operating at placement speeds up to several thousand components per hour. This packaging supports reflow soldering at peak temperatures up to 260°C per IPC/JEDEC standards.
For a backplane design requiring 56 signals, when is TSM-128-04-F-DH-A-K-TR preferred over a single-row connector?
When PCB real estate is constrained, the dual-row TSM-128-04-F-DH-A-K-TR routes 56 signals through a footprint roughly half the length of a single-row 56-pin alternative at 0.100" pitch, saving approximately 35 mm of board edge space while maintaining standard 2.54 mm inter-pin clearance for hand soldering or rework.
