The M16 Fast-Lock Weatherproof Connector is a medium-sized circular interface featuring a 16 mm coupling body and a push-lock or bayonet quick-release ring that engages and seals in a single push-and-twist motion—no spanner, no multiple rotations, no heat-shrink tubing. It occupies the middle ground between M12 (sensor-grade, ≤4 A) and M20 (heavy power, 20 A) in the industrial connector hierarchy, delivering up to 10 A per contact at 300 V AC/DC with IP67 (optional IP68) sealing in a compact, glove-friendly housing.
"Fast-Lock" refers to a spring-loaded sleeve or quarter-turn bayonet: align the guide slot → press inward → click into place with audible and tactile feedback → pull the sleeve or reverse-turn to release. Field-terminable screw and solder versions accept raw cable; pre-molded versions arrive factory-wired. It is the preferred choice when you need quicker mating than threaded M12, more pins than M12 allows, and a smaller footprint than M20 on outdoor LED, solar, sensor, and light-power installations.
Key Benefits
One-hand click lock, 3-second connection: Push-lock outperforms threaded M12/M20 on lamp posts, solar rails, and rack backs—one gloved hand, no tool, audible click confirms the seal. Reduces harness installation time by 30-50% on projects with 100+ nodes.
10 A / 300 V within a 16 mm shell: 2/3/4-pin power at 10 A, 5-pin at 8 A, 6(2+4)-pin at 10+5 A, 7/8-pin at 5 A signal—covers LED fixtures, 24/48 VDC battery taps, sensor and valve clusters, and combined power-plus-signal on a single barrel.
IP67 standard, IP68 optional (when mated): Dual silicone O-rings plus rear gland seal, verified for 1 m/30 min immersion; withstands rain, pressure washing, dust, UV radiation, and electrolyte mist on solar sites.
Field cut-to-length: Screw-terminal or solder-cup inserts accept 0.3-1.5 mm² (24-16 AWG), cable outer diameter 3-9 mm (via gland insert swap)—no factory cordset minimum order quantity, repair a damaged run in 8 minutes.
Keyed misconnection prevention plus colored shells: Polarized guide slot (A/B/D style or custom), black/blue/yellow/grey shells for Live/Neutral/Ground or positive/negative identification; no reversed polarity on DC battery links.
Industrial-grade contacts and housing: Copper alloy pins, gold flash (signal) or tin/silver (power), ≤ 5 mΩ contact resistance; PA66+GF / PBT shell UL94-V0, -40 °C to +105 °C, UV-stable.
Vibration-resistant, reusable: Spring lock withstands 5-200 Hz vibration (robots, AGVs, solar trackers), ≥500-3000 mating cycles depending on build; unscrew shell, re-terminate, reuse.
Fewer stock-keeping units than junction boxes: One connector family replaces field splices, tape, and small junction enclosures for branching, extending, and joining tasks.
Ratings: IP67 standard / IP68 optional; 300 V (2/3P), 125 V (4/5P), 60 V (7/8P); 10 A / 8 A / 5 A respectively

Competitive Advantages
Versus threaded M12: 2.5× the current (10 A vs 4 A), up to 8 pins vs M12's 17-pin limit aside, one-hand mating, better suited for power-plus-signal combinations
Versus threaded M20: same locking principle, 35% smaller profile, lower bill-of-materials cost, sufficient for ≤10 A runs without overspecifying
Versus junction box plus tape: IP-rated click seal, no cover screws that can seize, reusable, 70% faster field connection
Versus Anderson / SB / blade connectors: fully sealed, keyed, polarized, presents a clean appearance on outdoor fixtures
