JST Cable Assemblies

Custom JST Cable Assemblies

A JST cable assembly typically consists of:

  1. Connector Housing: The plastic component that houses the pins or sockets. These housings usually have polarization features to ensure they are connected correctly and may also include latching or locking features to keep them securely connected.

  2. Terminals (or Contacts): These are the metal components that are crimped onto the wire ends and inserted into the connector housing. They make the actual electrical connection when mated with their counterparts in the other half of the connector pair.

  3. Wires: Wires that are attached to the terminals. The gauge, insulation type, and color can vary based on the application.

  4. Strain Relief or Overmold: Some cable assemblies may include strain relief features or overmolding, which provides added protection to the wire-connector junction and can improve durability and longevity.

What is JST Connectors? 

A JST connector refers to electrical connectors manufactured by J.S.T. Mfg. Co. (Japan Solderless Terminal). JST produces a wide variety of connectors for various applications, including consumer electronics, automotive, and industrial markets.


Types Of JST Connectors:

JST connectors come in various pitches (distance between pins) and styles, including wire-to-wire, wire-to-board, and board-to-board connectors.

Some popular JST series include:

  • PH series: This is a 2.0mm pitch connector, often used in battery connections for small devices.

  • XH series: This is a 2.5mm pitch connector that can be found in many RC (remote control) battery applications.

  • SH series: A tiny 1.0mm pitch connector used in compact and densely packed electronics.


Benefit Of Using JST Connector Cor Cable Assemblies

JST connectors have become increasingly popular in a range of applications, especially in consumer electronics, because of several benefits they offer. Here are some of the primary advantages of using JST connectors for cable assemblies:

  1. Compact Design: JST connectors come in a variety of sizes, including very compact designs that are suitable for small devices. This makes them ideal for applications with space constraints, like wearable devices or drones.

  2. Polarity Protection: Most JST connectors have a design that prevents them from being connected backward, which can prevent potential damage to components or circuits.

  3. Variety: JST offers a wide range of connector types, from wire-to-wire, wire-to-board, and board-to-board, providing flexibility for various applications.

  4. Secure Connection: Many JST connectors have locking or latching mechanisms that ensure a secure connection, preventing accidental disconnections.

  5. Standardization: The use of standardized connectors like those from JST can simplify design and component sourcing. Since JST connectors are widely used, they are easily available and can be sourced from multiple vendors.

  6. Reliability: JST connectors are known for their durability and reliable performance, ensuring consistent electrical connections even in environments that may have vibrations or movement.

  7. Ease of Use: The design of JST connectors, with clear markings and keying features, ensures that they are easy to use and reduces the chances of incorrect connections.

  8. Scalability: With different series and pin counts available, JST connectors can be selected for various applications, whether it's a simple two-wire connection or a multi-pin data connector.

  9. Cost-Effective: JST connectors are often a cost-effective choice, especially given their reliability. Their widespread adoption also means economies of scale, often resulting in competitive pricing.

  10. Global Acceptance: Due to their reliability and standardization, JST connectors are accepted and used in electronic applications worldwide. This global acceptance can simplify design considerations for products intended for international markets.

  11. Color-Coded: Some JST connectors come in different colors, allowing for easy identification, which can speed up assembly processes and reduce mistakes.


When choosing a connector for your application, it's essential to consider the specific requirements, such as current, voltage, mechanical constraints, and environmental conditions. However, given the range and reliability of JST connectors, they are often a top choice for many cable assembly needs.
