m8 connector IP67 Waterproof Connector aviation plug M8 signal connector male and female connector

Product Description

The full-metal integrated structure delivers superior anti-corrosion, EMI shielding and mechanical impact resistance compared to plastic M8 connectors. Double silicone independent sealing rings at the mating surface and cable inlet realize stable IP67 protection against workshop cutting fluid, ink mist, fine metal dust and cooling water splashing. Screw-type solder terminals enable easy on-site wire assembly without specialized crimp tools, allowing customers to freely match custom-length PVC/PUR shielded/unshielded thin signal wires. All metal components pass a 48-hour neutral salt fog test, fully RoHS compliant, widely used in metal processing machine tools, digital printing equipment, laboratory precision micro testers and lightweight mini AGV obstacle detection modules.

Advantages

Full nickel-plated brass all-metal 360° shielding housing: Unique to metal M8 connectors, fully isolates electromagnetic interference from servo motors and frequency converters to avoid micro sensor signal drift and misdetection, a key upgrade over plastic unshielded M8 plugs.
Screw compression quick-wiring design: Eliminates soldering iron and crimp tool requirements; only a small screwdriver is needed to lock wire conductors, drastically cutting on-site assembly and maintenance time for printing/machinery production lines.
Double silicone dual-layer IP67 waterproof sealing system: Separate front mating and rear cable inlet gaskets form two independent waterproof barriers, reliably blocking printing ink mist, metal cutting fluid splashes and fine workshop dust infiltration.
Solid brass anti-corrosion mechanical structure: Superior impact, compression and salt fog resistance vs plastic M8 connectors, long service life in oil mist, humid metal processing and digital printing workshop harsh environments.
Straight inline universal layout: Linear cable outlet fits deep narrow sensor mounting holes on mini automation equipment, avoids 90° elbow lateral protrusion and cable extrusion fatigue cracking.
Multi-scenario industrial customization service: Supply single male/female plugs or pre-assembled finished harnesses of arbitrary lengths; small-batch prototype samples available for new miniature sensor, printing machinery and desktop collaborative robot product verification.

FAQ

Q1: What is the biggest advantage of full metal M8 plugs compared to plastic M8 connectors?

A: The closed all-metal housing forms a 360° electromagnetic shielding layer, which effectively filters EMI interference from servo motors and inverters to prevent sensor signal distortion; solid brass also delivers better anti-rust, impact and salt fog performance.

Q2: Do I need a soldering iron to wire this M8 screw-type connector?

A: No. It adopts rear screw compression terminals: strip wire insulation, insert the bare copper core into the terminal cavity, and tighten the screw with a small screwdriver to fix the wire firmly, no soldering required.

Q3: Can this full metal M8 plug work stably in machine tool workshops with cutting fluid and heavy oil mist?

A: The entire nickel-plated brass shell passes a 48-hour salt fog test; matched oil-resistant PUR shielded cable resists long-term corrosion by lubricating oil and water-based cutting fluid, paired with double silicone IP67 sealing to block liquid infiltration.

Q4: Does this straight full metal M8 plug support shielded twisted signal wires?

A: Yes, we can supply aluminum foil + copper braided overall shielded PUR cables. The all-metal shell connects to the cable shielding layer to form a complete ground shielding loop for maximum anti-interference performance.

Q5: What circuit applications are the 3Pin/4Pin M8 metal plugs suitable for?

A: 3Pin for 24V DC two power lines + single digital signal of basic proximity sensors; 4Pin for dual power + analog signal + temperature detection composite circuits of multi-function miniature transmitters.
