Circular M12 and M8 connectors are used in industrial automation to connect devices securely. M12 designs can also be used for fieldbus connections. M12 connectors are available as 3-, 4-, 5-, 6-, 8-, and 12-pin styles and are especially suited to harsh environments where washdown and corrosion may occur, as they usually come with IP65, IP68 and IP69K ratings.
The M8 connector is used specifically with industrial sensors. This connector features a waterproof 3-pin screw. It comes pre-assembled and will remain watertight even if submerged.
Common applications for these connectors include sensors, actuators, switches, PLCs, I/O boxes, and more in food and beverage processing, machine building, rubber and plastics, textile and printing presses as well as valves in HVAC systems.
A chief advantage to using M12 and M8 connectors comes in time spent installing wiring systems and maintaining them. This reduces setup time and the need to use electricians or qualified technicians.
