LD28/SP28 Rear Nut Mount Waterproof Connector 2-9 PinThe LD28/SP28 Rear Nut Mount Waterproof Connector is designed for heavier-duty panel wiring where a larger cable entry, stronger current capacity, and reliable sealing are required. With its rear nut mounting structure, this connector can be firmly fixed onto equipment panels, distribution boxes, control cabinets, outdoor devices, and industrial enclosures.As a large-size waterproof circular connector, the LD28/SP28 series is suitable for applications that need both high-load power connection and multi-core signal transmission. It supports 2 pin, 3 pin, 4 pin, 5 pin, 6 pin, 7 pin, and 9 pin options, giving engineers more flexibility when designing equipment wiring systems.
The connector is built with an IP68 waterproof structure to help protect the electrical connection from water, dust, humidity, and outdoor exposure. Its threaded coupling design allows the mating connector to be tightened securely, reducing the risk of loosening caused by vibration, cable movement, or long-term operation.The LD28/SP28 rear nut mount connector supports 10-15mm cable outer diameter and is suitable for 0.5-6mm² cable wiring depending on the pin layout. The 2 pin, 3 pin, and 4 pin versions can support up to 45A current, making this series suitable for higher-power equipment and outdoor electrical systems.
Made with flame-retardant PC/Nylon66 housing, PPS insulation, and plated brass contacts, the connector offers stable electrical performance, good insulation safety, and durable mechanical strength. The screw termination design also helps simplify wiring during assembly, maintenance, and field installation.Key AdvantagesLarger LD28/SP28 size for heavy-duty waterproof wiring Rear nut mount structure for secure panel installation IP68 protection against water, dust, and moisture 2-9 pin options for power and signal connection Up to 45A current capacity for high-load applications Supports 10-15mm cable outer diameter Threaded coupling helps prevent accidental loosening Screw termination for convenient wiring and maintenance Flame-retardant housing and durable internal insulation Suitable for OEM/ODM customized connector projects
