Analysis of Unionwell G23D Charging Gun Motor Electronic Lock Technology

In the DC fast charging scenario of new energy vehicles, the electronic lock (electronic lock motor) of the charging gun is the core component to ensure charging safety. In order to achieve precise control and status feedback in high temperature, high humidity, and complex outdoor environments, the well-known microswitch brand Unionwell has launched the G23D series of charging electronic lock microswitches. This article will provide a detailed introduction to the core parameters of this product and its application advantages in DC charging guns.

1、 Product Overview and Core Application Scenarios
The Unionwell G23D series electronic lock switch is a high-performance micro switch designed specifically for new energy charging facilities. It is mainly used in the electronic lock of DC charging gun motor, responsible for providing safe and stable control and gear status feedback. Its reliable locking mechanism can effectively prevent accidental gun pulling during the charging process, ensuring a stable connection between the vehicle and the charging station.

2、 Core technical parameters and protective capabilities
Reliable guarantee in harsh environments: IP 67 and wide temperature range
The working environment of a charging gun is complex and varied, and may face harsh conditions such as rain, snow, sandstorms, and high humidity, which puts extremely high demands on the protective capabilities of internal electronic components. The G23D series micro switch adopts a high sealing structure design, with a protection level of IEC IP67 standard, which can effectively prevent dust from entering and maintain stable performance under short-term immersion.
Meanwhile, this series of switches supports a wide operating temperature range of -40 ℃ to+85 ℃. This feature enables it to adapt to various climate conditions from cold winters in the north to hot summers in the south, ensuring accurate status feedback for vehicle control systems even in extreme temperatures.
Precise control and long lifespan: meeting high-frequency charging scenarios
During the charging process, the micro switch needs to cooperate with the vehicle's ECU (Electronic Control Unit) to complete real-time signal transmission of the lock/unlock status. The G23D series has clear gear feedback and precise positioning control, with a locking mechanism action stroke of 30 °± 2 °, ensuring accurate signal output.
In response to the high-frequency charging requirements of new energy vehicles, the electrical and mechanical lifespan of this series of switches has reached 60000 cycles. Its typical driving time is 200 ms (with an interval of 2 s), which meets the control requirements of the vehicle for signal response rhythm and balances sensitivity and stability.
Dual unlocking mechanism and structural strength
Safety and reliability design are integrated throughout the G23D series. It supports both electric and manual unlocking methods. In emergency situations such as motor drive failure, manual operation can be used to unlock, providing redundant protection for charging safety.
In terms of mechanical structure, its shaft strength is as high as 200 N, and the operating force is not less than 700 g. The sturdy internal contacts and housing design ensure stable electrical connection even in long-term insertion and vibration environments. In addition, its compact wired design also facilitates flexible installation inside the charging gun, compatible with multiple charging modules and electronic lock mechanisms

3、 Why choose G23D for DC charging gun?
In the process of DC fast charging, the generation of high current requires extremely high safety of the connector. The advantages of G23D micro switch are:
High safety: The reliable locking mechanism, combined with precise status feedback, effectively prevents gun pulling under load and protects personnel and equipment safety.
Strong stability: IP67 protection and wide temperature design solve the problems of water ingress and aging of charging guns in outdoor environments.
Good compatibility: As a standard micro switch component, it is easy to integrate into various DC charging gun motor electronic lock structures.

4、 Summary
For the charging system of new energy vehicles, although the micro switch is small, it is a "bridge" connecting physical locking and electrical control. The Unionwell G23D series micro switch provides a safe and stable control and status feedback solution for the electronic lock of DC charging guns, thanks to its IP67 high sealing performance, wide temperature range adaptability from -40 ℃ to+85 ℃, long lifespan of 60000 cycles, and reliable mechanical structure. It is a key link in ensuring the safety and reliability of the charging process.
