I. Core Specifications & Technical Highlights

1. Precision Design Enhancing Compatibility and Space Utilization

Pitch and Pin Configuration: The industry-standard 1.27mm pitch with a single-row, 2-pin (1×2P) layout meets basic circuit connectivity needs while saving PCB space, especially suitable for compact, high-density designs.

Dimensional Details: With a total length of 7.2mm (mating pin: 3.9mm, termination pin: 2.3mm, insulator height: just 1mm), this pin header ensures high installation precision and is well-suited for automated SMT processes.

2. Materials & Craftsmanship for Performance Assurance

Material: Made from high-conductivity alloy with gold-plated contacts, offering a low contact resistance of 20mΩ, excellent corrosion resistance, and a lifespan exceeding 5,000 mating cycles.

Manufacturing Process: Precision stamping ensures consistent pin dimensions. The through-hole (DIP) design supports soldering for enhanced mechanical retention with tensile strength >5kgf.

3. Outstanding Environmental Adaptability

Operating Temperature: Ranges from -40℃ to +105℃, ideal for industrial-grade applications, including automotive engine compartments and outdoor systems.

Protection Rating: Complies with IP20 standards and supports conformal coating for moisture, dust, and shock resistance, ensuring stable signal transmission in harsh conditions.

4. Superior Electrical Performance

Rated Current: 1A, suitable for low-power circuits such as sensor modules or debug interfaces.

Signal Integrity: Gold-plated contacts minimize signal loss, enabling high-frequency transmission for applications requiring precision like data acquisition and control signals.

II. Core Value & Application Scenarios

1. Foundational Component in Electronic Manufacturing
In motherboards, graphics cards, and industrial controllers, pin headers are essential for board-to-board connectivity, handling power and signal transmission. The KH-1.27PH180-1X2P-L7.2 simplifies PCB routing with its single-row layout and is especially well-suited for dense embedded systems. The 2-pin configuration allows for quick, easy integration of debugging or expansion ports.

2. Reliable Solution for Automotive Electronics
Automotive ECUs and sensor modules demand high resistance to heat and vibration. With an operating range of -40℃ to +105℃ and a through-hole structure, this pin header is built to endure the heat of engine bays and the mechanical shocks of driving, ensuring consistent signal delivery.

3. Ideal for Industrial Automation and IoT Devices
In environments like PLCs and industrial sensors, connectors must withstand electromagnetic interference and frequent mating cycles. The gold-plated contacts and reinforced base of the KH-1.27PH180-1X2P-L7.2 reduce the risk of poor contact, while bag packaging makes it easy to access on the production line—improving assembly efficiency.

III. Industry Trends & Selection Guidance

1. Development Trends in Pin Header Technology

Miniaturization & High-Density: With the rise of 5G and AIoT, ultra-fine pitch headers (e.g., 0.8mm) are increasingly used in wearables. Leading brands like Kinghelm are already investing in this frontier.

Multifunction Integration: Future pin headers may integrate power management or signal conditioning, such as NFC-enabled real-time parameter monitoring.

Eco-Friendly Materials: The adoption of bio-based plastics and lead-free solder aligns with global carbon neutrality goals.

2. Key Considerations for Product Selection

Pin Count & Pitch: Choose 2P, 4P, etc., based on your board layout. The 1.27mm pitch fits most standard sockets.

Mounting Method: Through-hole (DIP) is ideal for prototyping and small batches; surface-mount (SMT) suits automated production lines.

Environmental Adaptability: For industrial scenarios, prioritize models with wide temperature ranges and higher protection ratings.
