Standard M8 connectors (IP67/IP68 grade) have their own professional waterproof performance, which can meet the waterproof requirements of conventional industrial humid environments and short-term water immersion; additional sealing reinforcement is recommended for the scenarios with long-term water immersion and high humidity to avoid water ingress failure.
Technical Note: Homemade waterproof sealing treatment must be carried out on the premise that the connector is fully mated and locked; the sealant and waterproof tape used should be resistant to high/low temperature and industrial oil to avoid aging and falling off in harsh environments; it is recommended to regularly check the sealing state of the reinforced position and reprocess it in time if there is damage.
