IP67 Waterproof Wire Connectors M16 10A 2 3 4 Pin Screw Locking Solder Wire Connector
Waterproof M16 Panel Aviation Plug Socket IP67 10A 2/3/4 Pin Screw Locking Wire/Soldering Connector for Outdoor LED Light
The M16 Board-End Connector (also called M16 panel-mount receptacle, M16 flange socket, M16 PCB-mount circular connector) serves as the enclosure-faceplate interface of the 16 mm-class threaded circular system, built to IEC 61076-2-106 / IEC 60130-9 standards.
This connector brings field-side power and signal through enclosure walls directly onto control boards via an M16×1.0 coupling face and M18×0.75 panel thread, with rear tails terminated as 180°/90° PCB DIP pins, solder cups, Faston tabs, or flying leads. When mated with a standard M16 field plug, the panel penetration maintains IP67 sealing (IP68 optional).
Positioned between M12 (≤4 A) and M20 (≥20 A) connectors, it handles up to 7 A on 2/3-pin configurations at 250 V, 6 A on 4-pin, 5 A on 5-8-pin, down to 1 A on 24-pin configurations. This makes it ideal for 24 VDC auxiliary buses, sensor clusters, encoder+power combinations, PROFIBUS B-code, and AISG/RET telecom lines.
- Integrated Sealed Solution: Panel O-ring + M16 threaded lock provide IP67 protection at the sheet-metal wall; rear tail connects directly to PCB—eliminating flying leads through PG glands, internal terminal blocks, and loose cabinet wiring
- High Current Capacity: 2/3-pin: 7 A at 250 V, 4-pin: 6 A at 250 V—covers 24 VDC sensor power, IO-Link auxiliary, small AC/DC motor feeds, and fieldbus communications
- Coding Prevents Mismating: A-code (power/sensor), B-code (PROFIBUS/AISG/fieldbus) with keyed inserts prevent L/N/G or TX/RX reversal during installation
- Flexible Mounting Options: Front/rear/flange mounting with straight/90° PCB orientations saves depth on dense boards
- Industrial-Grade Construction: Phosphor-bronze/brass contacts with gold flash (3µ"+), PA66+GF inserts, Ni-plated brass or Zn-diecast shells with 360° shielding options
- Reduced BOM Complexity: Single component replaces panel gland + internal terminal block + strain relief + fly-wire for cleaner EMC and faster harness assembly
- Field Serviceable: Unscrew M16 field plug while flange receptacle remains panel-mounted—enables PCB replacement without cutting external cordsets
