M8 circular connector is a mainstream miniaturized connecting device in the industrial field. With a diameter of 8mm and a thread specification of M8*1.0, it is suitable for scenarios with limited space. It has a basic protection level of IP67, and some models reach IP69K. It can resist water, dust, oil, and cold, and maintain stability in a temperature range from - 40°C to + 125°C. It adopts a metal contact surface and a screw - lock design, with a contact resistance of ≤10mΩ, ensuring reliable signal and power transmission. It is widely used for connecting devices such as sensors and actuators.
☑Compact size: The M8 circular connector is renowned for its compact form factor, making it highly suitable for space-constrained applications.
☑Thread locking mechanism: The M8 circular connector is equipped with an M8×1.0 specification thread locking mechanism, ensuring the safety and stability of the connection. It can prevent accidental disconnection caused by vibration or other mechanical stress and is suitable for use in industrial environments with frequent vibration.
☑Used in industrial environments. Protection level: It has a protection level of IP67 or even higher, capable of dust and water resistance, and is suitable for applications in harsh environments.
☑Pin configuration: The M8 circular connector offers a variety of pin configurations, typically featuring a 3-pin or 4-pin design, suitable for different signal transmission requirements.
