Waterproof connectorWhat is the difference between metal head waterproof connectors and nylon head waterproof connectors, which are commonly used? Below is a detailed introduction by Shenzhen Dongshengda.

1. Electrical performance

The specified standard values for current level, contact impedance, voltage level, insulation resistance, etc. are consistent between metal and nylon.

2. Environmental parameters

The main environmental parameters are environmental temperature, humidity, signal interference, temperature emergency, atmospheric pressure, and corrosive environment. The use, storage, and transportation environment of waterproof connectors have a significant impact on their performance. In this regard, metal shells have better stability than nylon shells.

3. Termination method

The terminal connection method refers to the hardware contact and wire and cable connection method of the waterproof connector male and female connectors. There is no obvious difference between metal and nylon shells.

4. Mechanical life

The mechanical lifespan of waterproof connectors refers to the lifespan of the number of insertion and extraction times, which is generally specified between 1000 and 1500. The contact resistance, insulation resistance, contact resistance, insulation resistance, and pressure resistance of waterproof connectors shall not exceed the specified standard values.

5. Price

The metal of the waterproof connector shell is generally copper or aluminum, and the surface can be nickel plated to brighten or oxidized to blacken as needed. The price of metal shells is definitely better than nylon shells. The main advantage of metal shells is reflected in environmental parameters. If signal shielding is required or the usage environment is not good, it is recommended to use a metal shell, while nylon shells are better in other environments.
