What is a JST Connector?

 

JST connectors are electrical connectors developed and manufactured by the Japan Solderless Terminal (JST) company, formerly known as Delphi. They come in various series and are characterized by their small size, light weight, and ease of installation.

This article discusses some of the most common JST connector series, exploring their features, advantages, and applications.

 

JST Connector Series

JST connectors are electronic component connectors, acting as a bridge between circuit boards and cables. JST produces a wide variety of connectors, and some common series are listed below:

 

PH Series:

The PH series connector is a 0.5mm pitch single-row connector commonly used for connecting circuit boards and wires.

Features:

Small and Lightweight: PH series connectors are designed to be compact and lightweight, reducing the overall size and weight of electronic devices, making them suitable for space-constrained applications.

High Performance: The metal material used in the contact area of the PH series connectors offers excellent conductivity and stability.

Easy Installation: PH series connectors can be quickly installed and removed, reducing labor and time costs for device maintenance and improving efficiency.

PH series connectors are available in various colors and sizes to meet specific needs and are widely used in electronic devices such as computers, mobile phones, and cameras.

 

XH Series:

The XH series connector is a 2.5mm pitch single-row connector designed for low-voltage and low-current applications. It shares the same advantages as the PH series, such as being small, lightweight, and easy to install, but specifically caters to low-voltage and low-current applications like LED lights and electronic toys.

 

VH Series:

The VH series connector is a 3.96mm pitch single-row connector typically used for high-power and high-current applications. In addition to the small size, lightweight design, high performance, and color and size options of the PH and XH series, the VH series can also withstand high currents, making it suitable for high-power and high-current electronic devices. Due to these advantages, VH series connectors are widely used in various high-power and high-current electronic devices, such as motor controllers, power controllers, and home appliances.

 

NH Series:

The NH series connector, manufactured by JST, is a 2.5mm pitch double-row connector primarily used for connecting signal lines and low-current circuits, rather than high-current circuits. NH Series Double-Row Connector: The NH series is a double-row connector capable of connecting multiple signal lines and low-current circuits, commonly used in computer motherboards, monitors, printers, and other electronic devices.

 

SM Series and SH Series:

Both the SM and SH series connectors are small-sized connectors. The SM series has a 1.25mm pitch, while the SH series has a 1.0mm pitch. They are commonly used in electronic devices requiring small connectors, such as digital cameras, handheld game consoles, and smartphones.

These connectors are made of various materials, usually including a plastic housing, metal pins, and contact pieces. They are available in various forms, including through-hole, surface mount, and header types.

SM and SH series connectors are also frequently used in outdoor electronic devices due to their excellent waterproof and dustproof capabilities. Their small size and robust environmental protection make them indispensable in electronic device design.

 

ZH Series:

The ZH series connector is a high-density connector with a 1.5mm pitch. It is commonly used in high-density electronic devices such as laptops, tablets, and smartphones.

The ZH series connector can meet different application needs by varying the number of pins and arrangement.

 

JST Connector Features and Applications

1. Electronics: JST connectors are small, lightweight, and highly reliable, making them suitable for smartphones, tablets, digital cameras, and other consumer electronics.
2. Automotive: With the rapid development and increasing functionality of automobiles, JST connectors are used in automotive electronic systems for connecting sensors, control modules, lighting equipment, such as lights, horns, and audio systems.
3. Industrial Control: Offering stable performance and excellent transmission in harsh environments, JST connectors are resistant to high and low temperatures, high humidity, and corrosion. They facilitate connections between sensors, actuators, PLCs, and other equipment for automated production and equipment monitoring, significantly improving production efficiency and safety.
4. Medical Devices: Medical devices demand stability, accurate readings, and reliable data transmission for patient monitoring. JST connectors are commonly used for electrical connections in monitoring instruments and handheld medical devices.
