Design Features

The KH-A2009-2X04Y features a 2×4 PIN dual-row layout with a locking mechanism to secure the connection and prevent accidental disconnection due to vibration, handling, or external stress. Unlike other models, this connector does not include side wings, which results in a smaller overall footprint and simplifies installation in high-density boards or compact modules.

The connector’s design prioritizes ease of assembly, with pins and housing carefully engineered to ensure smooth insertion into mating components. The locking feature provides audible and tactile feedback, confirming a secure connection during installation. Its small size and dual-row structure make it ideal for applications requiring multiple signal lines in limited space.

Material and Safety

KH-A2009-2X04Y is manufactured from PA66 (Nylon 66), a high-performance engineering plastic known for its strength, dimensional stability, and chemical resistance. The connector can operate reliably within a temperature range of –25°C to +85°C, making it suitable for both industrial and consumer electronic environments.

In addition, the housing is rated UL94V-0 for flame retardancy, ensuring it self-extinguishes if exposed to fire or heat. This safety feature is critical for protecting devices and users in applications where thermal safety is a concern.

Electrical Performance

Kinghelm ensures KH-A2009-2X04Y delivers reliable electrical performance for a variety of applications. Key specifications include:

l Current rating: 3A AC/DC

l Voltage rating: 250V AC/DC

l Contact resistance: ≤ 20 mΩ

l Insulation resistance: ≥ 1000 MΩ

l Withstanding voltage: 800V AC/minute

These specifications make the connector suitable for signal transmission and moderate power delivery. Its low contact resistance ensures minimal voltage drop, and its high insulation resistance prevents leakage and short-circuit risks. Combined with the locking design, this connector provides stable and secure connectivity for compact modules and boards.

Applications

The KH-A2009-2X04Y locking housing connector is versatile across multiple industries and device types:

1. Embedded Control Boards: Perfect for small-scale PCBs in industrial or consumer devices where multiple signal lines are required.

2. Sensors and Actuators: Supports compact sensor interfaces, actuator modules, and control circuits, maintaining reliable connections in tight spaces.

3. Communication and Networking Devices: Suitable for small routers, IoT gateways, and networking modules where stable signal transmission is needed.

4. Consumer Electronics: Ideal for smart home devices, robotics, and portable electronics requiring compact and reliable connectors.

5. Automotive and IoT Modules: Can be applied in auxiliary electronic modules or vehicle interior electronics where vibration resistance and stable connections are important.

Its compact size, locking mechanism, and high-quality PA66 housing make KH-A2009-2X04Y a reliable choice for engineers designing high-density wiring layouts in modern electronics.
