What is an M12 connector and why is it used on waterproof PCs?
An M12 connector is a 12 mm threaded, circular industrial connector. It provides secure, vibration-resistant connections for signal, data, and power. It is ideal for waterproof panel PCs because the screw-lock design prevents accidental disconnection. Additionally, IP67, IP68, and IP69K ratings protect against dust, moisture, chemicals, and high-pressure washdown.
M12 connectors are especially suited for waterproof PCs because they help maintain enclosure integrity, support high-density I/O in compact spaces, and deliver reliable connectivity in harsh environments such as food processing, pharmaceutical manufacturing, water treatment, and outdoor industrial installations—where uptime and durability are critical.
