1.27mm pitch / 2.0mm pitch connector

1.27mm pitch and 2.0mm pitch connectors are widely used in electronics and industrial applications, each with different design requirements and applications. Due to the difference in pitch (distance between pins), each type has its own characteristics in connection density, durability, and power capacity, allowing you to select the optimal one according to the equipment and environment in which it will be used.

Features of 1.27mm pitch connector

1.27mm pitch connectors have narrow pin spacing of 1.27mm, making them suitable for small electronic devices that require high-density wiring. The main features are:

• High density connection: Design with narrow pin spacing allows many contacts to be placed in a limited space. It is especially suitable for small devices and space-saving designs on printed circuit boards.
• Low power/signal transmission applications: Suitable for small and precise signal transmission, mainly used in communication equipment, computers, industrial equipment, etc.
• lightweight and compact: Due to its small size and lightweight design, it is often used in portable electronic devices, laptops, tablets, etc.

Features of 2.0mm pitch connector

2.0mm pitch connectors have a wider pin spacing of 2.0mm, making them more durable and capable of delivering power than 1.27mm pitch connectors. Below are the main features:

• Improved durability: Due to the wide pin spacing and robust structure, it has high resistance to vibration and shock. Suitable for use in harsh environments such as industrial equipment, automotive equipment, and military devices.
• High power transmission:Has a larger current capacity than 1.27mm pitch, making it suitable for applications that require power supply.
• Easy to handle: Wide pin spacing makes assembly and maintenance easy, and handling during the manufacturing process is easy.

Applications and fields of application

1.27mm pitch and 2.0mm pitch connectors are selected depending on the application and design needs.

• 1.27mm pitch：

• Small electronic devices (smartphones, wearable devices)
• Communication/network equipment (routers, switches)
• Industrial automation (compact control equipment)

• 2.0mm pitch：

• In-vehicle equipment (engine control unit, vehicle infotainment)
• Industrial equipment (heavy machinery, manufacturing equipment with a lot of vibration)
• Defense and aviation equipment (connections that require durability)

Points to consider when selecting

To select the appropriate connector, it is important to consider the following points:

• Installation space: 1.27mm pitch is suitable when many contacts are required in a limited space, and 2.0mm pitch is suitable when large current or durability is required.
• Power capacity: You need to check whether it can meet the power requirements of the device you are using.
• Environmental resistance: The more robust 2.0mm pitch is suitable for environments with large vibrations, shocks, and temperature changes.
• Maintainability: 2.0mm pitch with wide pin spacing makes removal and maintenance easy.

In conclusion

1.27mm pitch and 2.0mm pitch connectors have different characteristics depending on their pitch size, and are important elements that support the design according to the application. 1.27mm pitch is optimal when a small, high-density connection is required, and 2.0mm pitch is optimal for applications that require large power supply or durability, and the optimal selection is required depending on the equipment specifications and usage environment.
