Waterproof Connector 7W2

Waterproof D Sub Ip67 connector is a high-performance connection solution designed precisely for these harsh challenges. Ip67 Connectors 7 Pin is a professional-grade connector that integrates high current-carrying capacity, IP67 or higher protection rating, and a rugged metal shell. It is suitable for various scenarios requiring stable power and signal transmission in harsh environments such as high humidity, dust, vibration, and corrosion. The 7W2 metal high-current waterproof d sub connector  generally achieves an IP67 rating or higher, meaning it is completely dust-tight and can function normally after being submerged in 1 meter of water for 30 minutes. Some models can be customized to IP68, providing long-term continuous immersion protection.Sub D Connector 7 Pin is PANDI’s primary product.

90° Right-angle PCB Mount Type: The right-angle bent pin design effectively saves internal equipment space, making it suitable for compact layouts. It meets customers' special space requirements, effectively saves space, and maintains stable transmission performance. The 7 pins feature gold-plated solid machined contacts, ensuring stable output, strong conductivity, low resistance, and long service life. Environmentally friendly materials comply with EU environmental requirements.

Its core advantage lies in "handling power and signal in one connector":

7 signal pins/sockets: Responsible for data or control signal transmission.

2 high-current pins/sockets: Responsible for high-power electrical transmission.

Bent (90°): Designed specifically for PCB termination, saves space, and solves the problem of vertical cable exit.

Metal waterproof: Adapts to harsh environments.

Based on these features, it is mainly used in fields that require simultaneous power supply and data transmission, especially in complex environments. Specific application scenarios include:

1. Industrial Automation & Control – the most core application area. Industrial equipment often needs to supply power to sensors or actuators while reading data.

Servo motors & drives: Needs power to drive the motor while transmitting encoder signals.

PLC systems: Used for I/O module connections.

Industrial robots: Joint connections require compact 90° design to fit tight spaces.

Variable frequency drives: Control panel to main board connections.

2. New Energy & Energy Storage – high current capacity and waterproof/dustproof features make it ideal for outdoor or high-interference environments.

Energy storage battery cabinets (ESS): Connections between battery modules (power + communication).

Photovoltaic inverters: DC side connections in solar power systems.

Charging piles/guns: Internal connections between control units and main boards.

3. Professional Audio/Video & Broadcast Equipment – analog signals and power often need isolation, but the connector integrates them.

Professional amplifiers: Transmit audio signals while providing trigger voltage.

Broadcast cameras: Outdoor broadcast vans or fixed positions require waterproofing and stable signal transmission.

Stage lighting: Control and power supply for high-power LED luminaires.

4. Rail Transit & Marine – metal shell provides excellent EMI/RFI shielding to prevent signal interference.

Train control systems: Signal and low-voltage power supply at carriage connections.

Marine electronic equipment: Navigation or communication devices on deck (IP67 waterproof required).

5. Medical & Test Equipment – high-end medical imaging (e.g., CT/MRI): Probe to console connections. Automated test equipment (ATE): Test fixture to mainframe connections; 90° design is often used inside test racks.

6. Military & Aerospace – radar systems: High reliability requirements. Ground support equipment: Needs to operate in harsh field environments.
