KH-A42002-2X2AW 4.2 mm Right-Angle Wire-to-Board Connector

In circuit board design, connectors are often an “unnoticed” component that can nevertheless determine the success or failure of an entire product. The reliability of wire-to-board connections has a significant impact on whether equipment can be assembled smoothly and operate stably over the long term. When engineers need to route wires from the side of a PCB and neatly guide cables toward one side of an enclosure, a well-designed right-angle connector can greatly simplify the overall layout. Kinghelm’s KH-A42002-2X2AW is specifically designed to meet this type of side-wiring requirement.

Let’s start with its most obvious mechanical feature. The KH-A42002-2X2AW adopts a standard 4.2 mm pitch, a widely used dimension in industrial and consumer electronics applications. Its compatibility is excellent, and the corresponding wire terminals and crimping tools are mature and readily available, helping reduce overall costs from component selection through mass production.

The product features a 2×2P pin configuration, with four pins arranged symmetrically in two rows. This structure can support two independent power or signal channels while maintaining balanced mechanical forces during mating, helping prevent pin deformation or poor contact caused by uneven loading.

Key Specifications

• Brand: Kinghelm
• Part Number: KH-A42002-2X2AW
• Pin Configuration: 2×2P
• Pitch: 4.2 mm
• Mounting Type: Right-angle
• Rated Current: 7 A
• Operating Temperature: -25°C to +85°C
• Rated Voltage: 600 V

The right-angle mounting configuration is the core highlight of this product. Compared with a straight connector, the pins of a right-angle connector are positioned parallel to the PCB after soldering, allowing the cable to exit parallel to the board surface. This makes it particularly suitable for applications where circuit boards are installed closely together inside an enclosure and cables need to be routed sideways.

This configuration not only reduces cable bending stress but also makes wiring and maintenance more convenient, making it an ideal choice for space-constrained equipment.

In terms of electrical performance, this connector delivers practical and reliable specifications. With a rated current of 7 A and a rated voltage of 600 V, it provides sufficient current-carrying capability for power transmission and signal distribution in most small- and medium-power equipment. The 600 V rated voltage also provides ample electrical margin for applications such as industrial control systems, LED drivers, and power modules.

With an operating temperature range of -25°C to +85°C, the connector can operate reliably in conventional industrial environments as well as in certain outdoor equipment applications.

In terms of materials and manufacturing processes, the KH-A42002-2X2AW is equally well engineered. The housing is made of PA66 engineering plastic, which offers excellent heat resistance and mechanical strength and is less prone to deformation or cracking during long-term use.

The transparent housing allows assembly personnel to visually inspect the pin positions and mating status, making production-line inspection and troubleshooting more convenient. The housing has a UL94 V-2 flammability rating, which helps limit the spread of flames in the event of abnormal overheating or a short circuit, adding another layer of safety to the overall equipment.

The contacts are made of brass with tin plating, combining good electrical conductivity with oxidation resistance and durability during repeated mating cycles. This helps maintain stable contact resistance and reliable signal transmission over long-term use.

In terms of applications, this wire-to-board connector is widely suitable for LED lighting fixtures, household appliances, power adapters, industrial control boards, and other applications requiring reliable connections between wire harnesses and PCBs.

Whether used for power input, signal distribution, or interconnection between control boards and functional boards, the KH-A42002-2X2AW can help engineers shorten development cycles and improve production yield through its stable electrical performance and convenient installation.

Overall, the Kinghelm KH-A42002-2X2AW wire-to-board connector combines a mature 4.2 mm pitch platform, reliable right-angle configuration, and solid electrical specifications, achieving a good balance between performance, cost, and assembly convenience.

For engineers looking for a cost-effective solution for side-entry wiring, the KH-A42002-2X2AW is worth considering as part of the connector selection process.
