Kinghelm Dual-Row Housing Connector KH-A2009-2X12Y: Combining Stable Transmission and Safe Connection

Product Overview

In modern electronic systems, reliable connectors are essential for ensuring seamless signal and power transmission. The Kinghelm KH-A2009-2X12Y dual-row housing connector is specifically engineered to meet the demands of industrial, consumer, and automotive applications where stability, safety, and compact design are crucial. This 2×12 PIN connector delivers high-density connectivity while maintaining secure mechanical and electrical performance.

Designed as a wire-to-board connector, the KH-A2009-2X12Y allows for compact placement on printed circuit boards (PCBs) while supporting multiple signal channels. Its dual-row configuration maximizes space efficiency and simplifies complex wiring layouts. With a standard 2.0mm pitch, this connector provides a reliable interface for both signal and moderate current applications.

Design Features

The KH-A2009-2X12Y connector features a dual-row, 2×12 PIN layout that enables high-density connections without compromising stability. Its locking mechanism ensures a secure fit, preventing accidental disconnection caused by vibration or mechanical stress. Unlike some other models, this connector does not have side wings, resulting in a more compact footprint suitable for densely packed electronic assemblies.

The design also considers user experience during assembly. The connector’s pins are precisely aligned to facilitate smooth insertion into mating components, reducing assembly time and minimizing errors. Its dual-row design is particularly advantageous for applications requiring multiple power and signal lines within a limited PCB area.

Material and Safety

The housing of KH-A2009-2X12Y is made from PA66 (Nylon 66), an engineering-grade thermoplastic known for its high mechanical strength, dimensional stability, and chemical resistance. This material can withstand a wide operating temperature range from -25℃ to +85℃, making it suitable for both industrial and consumer electronics.

Moreover, the connector’s housing meets the UL94V-0 flame retardancy standard, ensuring that it self-extinguishes in the event of exposure to fire. This safety feature is critical for devices operating in environments with potential thermal hazards, helping to protect the device and users from fire risks.

Electrical Performance

Kinghelm ensures that the KH-A2009-2X12Y delivers robust electrical performance suitable for a wide range 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 parameters allow the connector to reliably transmit both data and power while minimizing voltage drops and ensuring stable signal integrity. The combination of low contact resistance and high insulation resistance makes it suitable for critical industrial, automotive, and consumer applications where reliability is paramount.

Applications

The KH-A2009-2X12Y dual-row housing connector is widely applicable across multiple industries:

1. Industrial Automation: Ideal for PLC modules, control boards, and sensor interfaces where vibration and thermal stability are essential.

2. Communication Equipment: Ensures stable signal transmission in networking devices, routers, and communication modules.

3. Consumer Electronics: Suitable for smart home devices, robotics, and household appliances that require reliable multi-pin connections.

4. Automotive Electronics: Can be used in vehicle diagnostic modules, battery management systems, and infotainment systems, providing secure connections even under vibration.

5. IoT Devices: Supports compact modules and embedded systems requiring high-density signal connections.

The combination of a secure locking mechanism, dual-row structure, and high-quality materials makes this connector a versatile choice for engineers seeking reliable wire-to-board connections.
