JST 4 Pin Connector Types
Introduction:
JST (Japan Solderless Terminal) connectors are commonly used in electrical and electronic applications due to their reliability and ease of use. This article will provide an overview of the different types of JST 4 pin connectors and their specific uses.
I. JST XH Series:
The JST XH series connectors are widely used in the electronics industry for connecting wires to printed circuit boards (PCBs). These connectors have a pitch of 2.5mm and are primarily used for low voltage and low current applications. The XH series connectors feature a secure locking mechanism that ensures a reliable connection, making them suitable for use in consumer electronics, computer peripherals, and LED lighting systems.
II. JST PH Series:
The JST PH series connectors are smaller and more compact than the XH series. With a pitch of 2.0mm, these connectors are commonly used in applications where space is limited. They are designed for higher current and voltage ratings compared to the XH series, making them suitable for various power supply applications. The PH series connectors are often found in portable electronic devices, such as laptops, tablets, and mobile phones.
III. JST EH Series:
The JST EH series connectors are designed for higher current and voltage requirements, making them suitable for power distribution applications. These connectors have a pitch of 2.5mm and can handle currents up to 5A. The EH series connectors feature a robust design with a secure locking mechanism, providing a reliable connection in harsh environments. They are commonly used in automotive applications, industrial equipment, and power distribution units.
IV. JST SM Series:
The JST SM series connectors are commonly used for wire-to-wire and wire-to-board connections in applications that require a higher current carrying capacity. These connectors have a pitch of 2.54mm and can handle currents up to 3A. The SM series connectors are often used in the automotive industry, as well as in audio and video equipment.
Conclusion:
JST 4 pin connectors provide a reliable and efficient solution for a wide range of electrical and electronic applications. The XH series, PH series, EH series, and SM series connectors offer different specifications and features to meet the specific requirements of various applications. Whether it’s connecting wires to PCBs, power supply applications, power distribution systems, or audio and video equipment, JST connectors are trusted components that ensure a secure and stable connection.
