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 shape, making it highly suitable for applications with limited space.
☑ Threaded Locking Mechanism: The M8 circular connector is equipped with a threaded locking mechanism of M8×1.0 specification, ensuring connection safety and stability. It can prevent accidental disconnection caused by vibration or other mechanical stresses, and is suitable for industrial environments with frequent vibrations.
☑ Industrial Environment Applications. Protection Level: Its protection level reaches IP67 or even higher, providing dust - proof and waterproof capabilities, thus being applicable to applications in harsh environments.
☑ The housing is usually made of zinc alloy or PBT engineering plastics. These materials are not only robust and durable but also have excellent chemical corrosion resistance.
