Key Features
- 7-position single-row horizontal layout on 2.54 mm pitch minimizes PCB footprint for compact SMT designs
- Gold-plated (G) contacts ensure low-resistance, corrosion-resistant connections suitable for high-reliability signal interfaces
- SH horizontal orientation allows mating from the side, enabling low-profile board-edge interconnection
Applications
The TSM-107-01-G-SH-A is used in low-profile sensor interfaces, compact embedded controller boards, and edge-accessible test points requiring horizontal mating on a 7-pin, 2.54 mm pitch SMT footprint. The gold contact finish suits precision analog and high-cycle-life digital interfaces in medical instruments, robotics, and laboratory equipment. Its single-row horizontal format is ideal for slim enclosures where vertical clearance is limited.

Frequently Asked Questions
What is the contact orientation and pitch of the TSM-107-01-G-SH-A?
The TSM-107-01-G-SH-A uses a single-row horizontal (SH) orientation on a 2.54 mm (0.100 inch) pitch with 7 positions. The horizontal configuration allows a mating cable or header to connect from the board edge, achieving a mated height profile as low as approximately 8.5 mm above the PCB surface.
Why choose gold-plated contacts on TSM-107-01-G-SH-A versus tin-plated alternatives?
The G suffix specifies gold plating over the contact surfaces, typically 0.38 µm or greater Au over nickel. Gold provides stable contact resistance below 20 mΩ even after thousands of mating cycles and resists oxidation in humid or mildly corrosive environments, making it preferable for precision analog signals and high-reliability applications over standard tin-plated contacts.
In which application areas does the 7-pin horizontal TSM-107-01-G-SH-A offer a layout advantage?
The 7-position horizontal layout of TSM-107-01-G-SH-A is advantageous in slim handheld instruments, side-panel I/O on rack cards, and wearable device PCBs where vertical connector clearance is under 10 mm. The SMT footprint keeps the board stackup simple while the horizontal exit direction aligns with enclosure side-access ports without additional cable bending.
How does TSM-107-01-G-SH-A current rating affect power rail routing on a compact board?
Each of the 7 contacts supports 3 A continuous current, yielding a combined capacity of 21 A if all pins are dedicated to power. In practice, designers typically allocate 2 to 4 pins for power and ground with the remainder for data, leaving sufficient margin on a 3.3 V or 5 V rail without derate on an FR4 PCB at 25°C ambient.
