This 4-core male round connector is an industrial grade interconnect component used for electrical signal and power transmission, mainly solving the problem of fast cable docking and stable conductivity between devices. It adopts A-type foolproof coding design, effectively preventing accidental insertion, and is suitable for automation equipment, instruments and control cabinets that require high reliability connections. This product supports a maximum voltage of 250V and a current of 4A, which can meet the connection needs of most small and medium power devices. It is an efficient solution to replace traditional soldering or complex wiring, ensuring stable contact even in vibration environments.

  This circular connector focuses on durability and conductivity in its specification design. The pin terminals are made of high-quality solid brass and have a surface treated with 3 μ gold plating, significantly reducing contact resistance and enhancing oxidation resistance. Its wiring method adopts convenient locking screw type terminals, supporting various wire gauges from 24AWG to 20AWG (0.25mm ² -0.5mm ²), suitable for connecting wires of different thicknesses. The product has a non shielded structure, a straight head design for easy installation in narrow spaces, and strict industrial manufacturing standards to ensure the airtightness and mechanical strength of each contact, in compliance with conventional electrical safety regulations.

  When selecting, it is necessary to clarify that this product is a 4-core male connector and has an A-type code. It is important to confirm that the female connector of the socket is also the corresponding A-type code to match the key position and avoid situations where it cannot be physically inserted. Due to its unshielded structure, it is not recommended for sensitive analog signal transmission in strong electromagnetic interference environments. It is more suitable for power supply, digital signals, or general control circuits. If high current transmission is required, please note that its rated current is 4A, exceeding this range may cause heating; At the same time, confirm that the wire diameter is between 0.25mm ² and 0.5mm ², and that cables that are too thick or too thin cannot be securely fixed with locking screw terminals.

  When installing the circular connector, it is recommended to use a screwdriver of appropriate size to tighten the terminal screws to avoid damaging the threads or compressing the wire core with excessive force. After wiring is completed, a tensile test should be conducted to ensure stability. In daily maintenance, regularly check the fit tightness between the plug and socket, as well as whether there are serious signs of wear or oxidation on the gold plating layer, especially when used in high temperature or high humidity environments. Common faults are often caused by poor contact, usually due to loose screws or oxidized terminals. Re tightening or cleaning the contacts can restore them, and the working temperature range is -40 ° C to 105 ° C, covering the vast majority of industrial site environments.
