3.5-R5

The "3.5-R5 from JST" refers to a specific type of connector produced by JST (Japan Solderless Terminal), a well-known manufacturer of electrical connectors. The "3.5-R5" designation typically indicates a particular model or series within their product line, often used in various electronic applications.

Description:

1. Connector Type: The 3.5-R5 is likely a type of wire-to-board connector, which is designed to connect wires to a printed circuit board (PCB). This type of connector is commonly used in consumer electronics, automotive applications, and industrial equipment.

2. Pin Configuration: The "3.5" in the name suggests that the connector may have a pitch (the distance between the centers of two adjacent pins) of 3.5 mm. The "R5" could indicate a specific configuration or series within the 3.5 mm pitch category, possibly referring to the number of pins or the arrangement of the connector.

3. Material and Build: JST connectors are typically made from durable plastic materials that provide insulation and protection against environmental factors. The pins are usually made from metal, often plated with gold or tin to ensure good conductivity and resistance to corrosion.

4. Design Features: The 3.5-R5 connector may feature a locking mechanism to ensure a secure connection, preventing accidental disconnection. It might also have a polarized design, which ensures that the connector can only be inserted in one orientation, reducing the risk of incorrect connections.

5. Applications: This type of connector is versatile and can be found in various applications, including:

   • Consumer electronics (e.g., audio devices, home appliances)
   • Automotive systems (e.g., lighting, sensors)
   • Industrial machinery (e.g., control systems, automation equipment)

6. Electrical Specifications: While specific electrical ratings can vary, JST connectors generally support a range of voltages and currents, making them suitable for low to moderate power applications. The 3.5-R5 connector would typically be rated for a specific current capacity, often around 3A to 5A, depending on the design and materials used.

7. Color Coding: JST connectors often come in various colors, which can help in identifying different signal types or power lines in a wiring harness. This color coding aids in organization and troubleshooting during assembly or maintenance.

8. Mounting Options: The 3.5-R5 connector may be available in different mounting styles, such as through-hole or surface mount, allowing for flexibility in PCB design and assembly processes.

In summary, the 3.5-R5 from JST is a compact, reliable connector designed for efficient wire-to-board connections in a variety of electronic applications, characterized by its 3.5 mm pitch, durable construction, and secure locking features.
