Metal and plastic Push-Pull Circular Connectors

Circular connectors are mainly used in the industrial world, home appliances (M5, M8, M12, M16 circular connectors/panel mount, waterproof cables). It is a cylindrical multi-pin electronic connector with a round plug surface, which is used for inter-plug connection between devices. Circular connectors contain contacts for data and power transfer and typically include low frequency ring connectors, radio frequency coaxial connectors and audio connectors.
The cylindrical structure of circular connectors is inherently strong, providing greater strength than any other shape. The shell is made of zinc alloy or PBT engineering plastic material, and the connection adopts 1/4 quick bayonet connection, plug-in connection, latch connection, quick-plug connection, thread connection, push-pull connection, etc.

The main application of circular connector
Where multiple connectors are used to interconnect components and cables, and cables and cables, circular connectors are the first choice.
Widely used in sensors, actuators, encoders, motors, industrial grating light curtains, factory automation process control, equipment batteries, semiconductors, packaging label printing equipment, fieldbus, industrial equipment, marine electronics NMEA 2000, rail transit, EMS Circuit board components, LED outdoor displays, outdoor LED lighting, etc.

why is it round
A series of IEC specifications define circular connectors. This is IEC61076, and IEC61076 defines various connectors. Regarding circular connectors, there are mainly circular connectors of various specifications such as M5, M8, M12, M16, etc., and their external dimensions, pin distribution, mechanical and electrical characteristics, etc. are specified.
For example, the A code of the M12 connector is used to transmit direct current, standard 24VDC and standard sensor signal interface, and the B code is used for DC signals, such as early Profibus, Interbus and other field buses. C code is used for alternating current, standard 24/110/230VAC, mostly used in the United States. D code is mostly used for Ethernet communication such as Profinet, Ethernet, CC-LinkIE, etc. X encoding is used for Gigebit Ethernet and more.

M8 circular connector
The common M8 connector has a thread specification of M8×1.0. Therefore, unlike the many specifications of M12, M8 only has 3-4 codes and five digits. Because the M8 pin pitch is too small, it is not suitable for high voltage applications, only suitable for occasions below 50V AC or 60V DC.
