NF7220-02PA

IP67 2 Pin Waterproof Connectors

Our IP67 waterproof connector brings you superfast secure connections with total safety against dust and water immersion. This circular connector has quick-connect technology with industrial-grade environmental protection. The NF7220-02PA model features high-temperature plastic housing, gold-plated pin waterproof design, and N52 magnets. This means you get the best, superior performance in the most intense industrial environments.

What is an IP67 Waterproof Magnetic Connector?

The IP67 waterproof magnetic connector is a specialized electrical connection system that combines magnetic coupling technology with complete environmental protection against dust and water immersion. This industrial circular connector features a unique design with high-strength N52 magnets that create an above 400g coupling force while maintaining perfect alignment through north-south pole orientation. The connector’s weatherproof design ensures total dust protection and water immersion resistance, making it ideal for applications where traditional wire connector systems would fail.

Unlike conventional male female cable assemblies that require precise alignment and physical force to engage, our magnetic system allows for quick, one-handed operations even in low-visibility environments. The precision-engineered 2pin housing made from high-temperature plastic (UL 94V-0) provides outstanding durability, while the gold-plated copper contacts ensure optimal electrical performance throughout the socket’s lifespan.

Technical Drawing Specifications

• Overall dimensions: 21.3 mm x 8.30 mm x 6.30 mm (compatible with thread mounting)
• 2 pins with 0.60 mm diameter
• Housing material: High-Temperature Plastic UL 94V-0, BLACK
• Pin plating: AU 5 μ” MIN OVER 50~120 μ” Ni

How does the IP67 Rating Protect Your Connections?

The IP67 rating provides complete protection against dust ingress and temporary water immersion up to 1 meter for 30 minutes. This international protection marking, established by the International Electrotechnical Commission (IEC) & Deutsches Institut für Normung (DIN) under standard IEC 60529, offers significantly better protection than many competing products like IP44-rated systems. For applications requiring reliable vibration resistance in outdoor environments, this higher protection rating ensures connection reliability even with screw terminals exposed to challenging conditions.

The connector’s specialized waterproof seal technology creates a permanent barrier between the housing components, while the precision-engineered interface between magnetic surfaces maintains water-tight protection even after thousands of connection cycles. This level of protection approaches IP68 standards while maintaining easier connection and disconnection capabilities.

Environmental Testing Standards

• Dust protection: Complete ingress protection (first digit: 6)
• Water protection: Immersion up to 1m for 30 minutes (second digit: 7)
• Salt spray resistance: Magnet 24 Hours, Contact 48 Hours
• Mechanical durability: Rated for 500+ mating cycles under environmental stress

What are the Technical Specifications of Our Magnetic Connector?

The connector’s electrical specifications ensure reliable power delivery for applications from control systems to critical industrial equipment while maintaining safety margins. Our model NF7220-02PA undergoes 100% quality inspection including terminal resistance testing, magnetic force verification, and full environmental simulation to guarantee performance.

How does the Magnetic Connection System Work?

The magnetic connection system utilizes precision-aligned north and south poles to create a self-orienting connection that engages only when properly aligned. This power connector consists of two components: a male connector with exposed pins and a female socket with corresponding contacts. When brought within proximity, the N52 magnets pull the connectors together with over 400g of force, ensuring proper pin alignment and creating a secure electrical connection.

The self-aligning nature of magnetic poles ensures that connectors can only engage in the correct orientation, eliminating the risk of reversed polarity connections. This magnetic guidance system makes connections possible even in low-visibility conditions or when direct line-of-sight is not available.

Additionally, the magnetic connection provides built-in strain relief for the wire, as excessive force will cause a clean break rather than damaging the connector or attached cables. This quick-disconnect capability protects equipment during accidental pulls or drops while maintaining the waterproof integrity of each connector half.

Magnetic Connector Construction

• North-South pole orientation for self-alignment
• Waterproof glue between housing and components for IP67 sealing
• Precise pin alignment through magnetic guidance
• Working height (quiescence) optimized for 50 mOhm maximum contact resistance
• The overmolding process creates seamless protection over critical junction points

Why Choose Magnetic Connectors Over Traditional Options?

Magnetic connectors offer significant advantages over traditional screw-type or push-in connectors, particularly in challenging environments. The quick-connect capability reduces connection time by up to 80% compared to threaded 2pin or 3 pin alternatives, with single-handed operation even when wearing gloves. This waterproof plug is a very useful solution for time-sensitive applications like medical equipment setup or field maintenance.

Unlike conventional screw-locking systems that wear down with repeated connections, our magnetic system maintains consistent performance over thousands of connection cycles. The absence of mechanical lock mechanisms eliminates common failure points like stripped threads, broken latches, or bent pins that plague traditional panel mount connectors.

The magnetic system also provides enhanced safety through instant disconnection when excessive force is applied, protecting both equipment and personnel. This “break-away” functionality is particularly valuable in applications where cable entanglement could cause equipment damage or personal injury.

Key Advantages of Magnetic Connectors

• Quick-connect capability with above 400g magnetic mating force
• Self-aligning design for perfect connection every time
• Break-away safety feature for equipment protection
• No mechanical wear components for extended service life
• Waterproof integrity is maintained through separation and reconnection
• Pollution degree 3 rating, suitable for conductive contamination environments

What Industries Benefit Most from IP67 Magnetic Connectors?

Medical device manufacturers benefit significantly from these connectors, particularly in equipment requiring frequent cleaning or sterilization. The waterproof connector with IP67 protection maintains integrity during washdown procedures while allowing quick disconnection for maintenance or reconfiguration.

Automotive and transportation systems utilize these waterproof male connectors in exterior sensors, lighting, and diagnostic ports exposed to harsh environmental conditions. The quick-connect functionality facilitates efficient assembly and maintenance, while the IP67 2 pin rating ensures performance through car washes, road spray, and extreme weather conditions.

As a manufacturer of high-quality circular connectors, we’ve designed these systems for diverse applications, including:

• Communications industry: Data transmission in marine and outdoor environments
• Automotive industry: Exterior sensors, lighting control systems

How do we Ensure Quality and Reliability?

As a reliable supplier, Promax Pogo Pin implements a comprehensive quality control system, testing each connector for electrical performance, magnetic strength, and environmental protection. Every connector undergoes contact resistance measurement at working height, ensuring consistent power transfer within the 50 mOhm maximum specification. Magnetic mating force testing verifies the above 400g connection strength required for secure operation.

Environmental testing for top quality includes salt spray exposure (24 hours for magnets, 48 hours for contacts) to verify corrosion resistance, particularly important for marine and outdoor applications. Full IP67 verification testing confirms that our 2 pin male connector meets international standards for environmental protection, with certification documentation available upon request.

Our manufacturing process utilizes high-precision injection molding with specialized waterproof glue application to create a permanent environmental seal. Gold-plated contacts undergo multiple inspection points to ensure conductivity and corrosion resistance throughout the connector’s service life.
