The Different Types of JST Connectors Explained

Types of JST Connectors

JST (Japan Solderless Terminal) connectors are widely used in electronics and electrical applications for their reliability and ease of use. They come in various types and sizes to accommodate different needs. Here are some common types of JST connectors:

1. JST XH Series

The JST XH series connectors are widely used for low-voltage applications, especially in the field of hobby electronics and battery packs. They feature a 2.5mm pitch and are available in various pin configurations, including 2-pin, 3-pin, 4-pin, and more. The XH series connectors are typically used for connecting balance leads in lithium-ion battery packs and are known for their secure and reliable connections.

2. JST PH Series

The JST PH series connectors are compact and commonly used in a wide range of applications, including consumer electronics, computers, and automotive electronics. They have a 2.0mm pitch and are available in different pin configurations. The PH series connectors are known for their secure latching mechanism, making them suitable for applications that require reliable connections in limited space.

3. JST GH Series

The JST GH series connectors are designed for higher current applications, typically in power supply and battery applications. They have a 1.25mm pitch and can handle higher current capacities compared to other JST connector series. The GH series connectors are commonly used in robotics, drones, and other applications that require reliable power connections.

4. JST SH Series

The JST SH series connectors are small, low-profile connectors with a 1.0mm pitch. They are often used in applications where space is limited, such as mobile devices, small electronics, and LED lighting. The SH series connectors are known for their secure friction lock and are designed to withstand vibration and physical stress.

5. JST VH Series

The JST VH series connectors are robust connectors suitable for high-current applications. They have a 3.96mm pitch and are commonly used in power supplies, automotive applications, and industrial equipment. The VH series connectors offer secure and durable connections, making them suitable for demanding environments.

6. JST ZH Series

The JST ZH series connectors are ultra-miniature connectors with a 1.5mm pitch. They are commonly used in applications that require high-density and space-saving connections, such as portable devices, sensors, and small-scale electronics. The ZH series connectors feature a secure locking mechanism and are suitable for low-power applications.

Conclusion

JST connectors are widely used in electronics and electrical applications for their reliability, compactness, and ease of use. The various types of JST connectors, such as the XH, PH, GH, SH, VH, and ZH series, cater to different pitch sizes, current capacities, and space requirements. Understanding the different types of JST connectors allows for the appropriate selection and usage of connectors based on the specific needs of the application at hand.
