Understanding the differences between various IP ratings is crucial when choosing waterproof connectors. IP67-rated connectors, like some M12 waterproof models, ensure protection from water immersion up to 1 meter for short durations and are perfect for applications such as industrial automation and factory equipment exposed to occasional splashes or wet cleaning procedures. On the other hand, IP68-rated connectors offer higher protection, capable of enduring continuous submersion in greater water depths, making them ideal for marine and underground applications that demand consistent operation in persistently wet conditions. Choosing the correct rating depends on your specific use case, but both certifications offer peace of mind in maintaining long-term signal integrity in challenging environments.
