SP21 5Pin PanelMount Aviation Waterproof Connector Socket for Industrial and Solar Applications Key benefits Reliable watertight connections for outdoor and harsh environments thanks to IP68 ingress protection. Secure, vibrationresistant locking keeps power and signal lines stable in industrial and mobile installations. Panelmount socket design makes installation neat and accessible while keeping wiring protected behind the panel. Five contact pins support combined power and signal wiring without extra adapters, simplifying system wiring. Compact circular form factor saves space and integrates cleanly into enclosures, junction boxes, and equipment panels. What it does Provides a secure, circular 5pin socket for connecting cables to panels and equipment. Seals the connection against dust and water to maintain electrical continuity and reduce maintenance. Enables straightforward wiring to equipment via a panelmounted connector that mates with the corresponding 5pin plug. Key features and attributes Model: SP21 5pin socket, panelmount aviation style connector. Function: Fixed panel socket for cable connections, designed to mate with SP21 5pin plugs. Compatibility: Works with standard SP21 5pin mating plugs used in industrial, solar, lighting, and control systems. Form factor: Circular, panelmount design for secure front or bulkheadstyle installation. Contacts: Five contact positions to carry power, ground, and signal lines as required by your application. Sealing: Designed for IP68level protection to resist dust and temporary immersion in water. Construction: Engineered for robust mechanical retention and repeatable mating cycles to support longterm installation. Installation and use notes Install into a standard SP21 panel cutout and secure with the provided mounting hardware. Route cables through the rear of the connector and make connections to the contact terminals according to wiring diagrams. Pair with the matching SP21 5pin plug for a complete waterproof cabletopanel connection. Periodically inspect the sealing surfaces and mating interface for debris to maintain performance in exposure settings. Practical applications Solar power systems: Connect solar panels, inverters, and junction boxes where outdoor sealing and reliable power transfer are required. Outdoor and industrial lighting: Provide protected power and control connections for LED fixtures, floodlights, and street lighting controllers. Industrial equipment and automation: Use on control panels, sensors, and motor controllers where a durable, sealed cable interface is needed. Why choose this connector Designed specifically to provide a compact, reliable, and sealed panel connection for power and signal in demanding environments. Reduces installation complexity by combining five contacts in a single mating interface and securing the connection against moisture and dust. Suited for repeated mating cycles while maintaining contact integrity and physical stability in industrial and outdoor deployments.
