The M18 Waterproof Plug (also referenced in the North American market as the 7/8-inch circular connector) is a mid-large threaded interconnect built on an M18×1.0 coupling nut (≈18 mm nut OD). It sits between M12 (sensor-grade, ≤4 A) and M20/M25 (heavy power) in the industrial connector ladder, delivering IP67 as standard and IP68 optional when mated. Capable of carrying up to 16 A per contact at 250-300 V AC/DC on 2-4 pin power builds, it's available as field-wireable screw/solder plug, molded-with-cable cordset, panel flange socket, or 90° right-angle configuration. This connector serves as the default sealed interface for larger sensors, valve islands, 24 VDC/230 VAC auxiliary power, outdoor LED trunks, and 7/8-inch industrial Ethernet/fieldbus taps where M12 lacks current headroom and M20 is over-sized.
Key Benefits
16 A / 250-300 V capacity in an 18-mm shell: Covers 24 VDC valve clusters, 230 VAC cabinet auxiliary feeds, and 48 VDC LED landscape trunks without requiring M20 connectors
IP67 locked, IP68/IP69K optional: Silicone O-ring face + M18×1 threaded nut + rear gland (cable OD 5-10 mm, PG9/PG13.5 class) survives 1 m/30 min immersion, hose-down, oil mist, and dust storms
Field-wireable OR molded options: Screw-clamp accepts 0.5-1.5 mm² (20-16 AWG), solder cup to 1.5 mm², IDC optional—enables on-site cable customization and quick repairs
2-17 pins, A-coded + hybrid configurations: A-code power/sensor (2/3/4/5/7/8/12/17-pin), 2+4 power+signal hybrid, keyed polarization prevents L/N/G reverse on DC LED and AC auxiliary runs
