M12 4 Pin Waterproof Connector Plug Socket Power Cable Copper Contact Industrial Sensor

Waterproof Plug M12 Waterproof Mount 4pin Plug Socket Power Cable Copper Contact M12 Sensor Actuator Connector

The M12 4-pin sealed interface system is a standardized circular connector featuring a threaded coupling mechanism, engineered to deliver consistent and reliable transmission of power, signals, and data in harsh industrial and outdoor settings. Defined by its precise 12mm metric threading, it creates a sturdy, vibration-proof, and fully protected link. As a critical component within automated and networked industrial environments, the A-coded 4-pin layout ensures continuous, dependable performance for sensors, actuators, controllers, and networking devices operating in the presence of moisture, dust, chemicals, and severe thermal shifts.

• Exceptional Sealing Performance: Achieves high Ingress Protection (IP) ratings such as IP67 (dust-tight, protected against temporary immersion) and IP68/IP69K (protected against prolonged immersion and high-pressure/steam jet cleaning), ensuring reliable function in damp, contaminated, or washdown-prone locations.
• Built for Durability and Strength: Connector bodies are constructed from high-grade materials including nickel-plated brass, stainless steel, or robust engineering thermoplastics like PA66, providing excellent resistance to corrosion, mechanical impact, and ultraviolet (UV) light exposure.
• Wide Temperature Tolerance: Functions reliably across a broad temperature span from -40°C to +105°C (with options extending to +125°C), making it suitable for diverse environments from freezer storage to high-heat machinery enclosures.
• Secure, Error-Proof Design: The threaded screw-lock (M12x1.0) ensures connections remain secure even under significant vibration. The A-code keying physically prevents incorrect mating of different signal systems, protecting connected equipment.
• Versatile Application Support: Offered with 3, 4, 5, 8, 12, and 17-pin layouts. The 4-pin A-code version provides:
  • Stable signal & standard power transmission: rated 4A, 30-250V AC/DC
  • Broad compatibility with proximity sensors, photoelectric sensors, and actuator interfaces
  • Reliable 100 Mbps fast Ethernet transmission in D-coded variants
• Easy Installation & Design Versatility: Available in both straight and 90-degree right-angle form factors. Supports multiple connection methods such as screw-clamp, crimp, solder cup, and PCB mount termination for flexible integration into various systems.
• Extended Service Life & Reliability: Designed for repeated connection cycles, with a rated mechanical life of ≥500 cycles for standard plastic-housed versions and over 10,000 cycles for all-metal variants, reducing long-term maintenance and replacement needs.
• Superior Electrical Specifications: Features gold-plated contacts to maintain minimal and stable contact resistance (≤5-10mΩ), high insulation resistance (≥100MΩ), and a high dielectric strength (withstand voltage ≥1000V AC).

• Universal Standard for Compatibility: Adherence to international standards (IEC 61076-2-101) guarantees effortless interoperability with components from leading global suppliers, facilitating easier procurement, system design, and integration.
• Optimized Uptime in Demanding Conditions: The integrated benefits of superior environmental sealing, a wide operational temperature range, and vibration resistance work together to reduce unplanned downtime and maintenance expenses in tough applications, offering a lower total cost of ownership.
• Forward-Looking System Design: The 4-pin A-code layout balances signal capacity and compact size, enabling a single cohesive connector family across diverse industrial sensor and actuator applications.
