The initial contact resistance of a single pair of contacts ≤20mΩ, which can effectively ensure that there is no obvious attenuation during signal and current transmission, and guarantee the stability of the whole transmission circuit.
Under normal temperature and humidity conditions, the insulation resistance ≥1000MΩ (500V DC) between each contact and between contacts and the shell, which can effectively prevent electric leakage and signal crosstalk between different circuits.
Technical Note: Regular detection of resistance parameters is recommended for M8 connectors used in harsh environments; keeping the contact surface clean, selecting connectors with gold-plated contacts and doing a good job of sealing and protection can effectively maintain the stability of resistance parameters and extend the service life.
