LD32/SP32 4 Pin Square 4-Hole Flange Connector IP68 WaterproofFor equipment that needs a fixed waterproof power interface, the LD32/SP32 4 Pin Square 4-Hole Flange Connector offers a strong and dependable panel connection solution. It is designed for larger cables, higher electrical loads, and installations where the connector must stay firmly mounted on the enclosure during long-term use.The square flange base is fixed with four screws, giving the connector excellent mounting strength on control cabinets, distribution boxes, machinery panels, outdoor enclosures, and power equipment. This structure is especially useful when the connector may face cable pulling, vibration, frequent maintenance, or repeated plug-in and unplug-out operations.
With a 4 pin configuration, this model is suitable for multi-core power wiring in industrial and outdoor systems. The LD32/SP32 size supports thicker cable assemblies and provides enough space for stable wiring, making it a good choice for equipment that requires a more powerful connector than compact waterproof series.The connector adopts an IP68 sealing structure to reduce the risk of water, dust, and humidity affecting the electrical contact area. After the mating side is tightened, the threaded connection helps create a firm lock between plug and socket, supporting safer operation in demanding working environments.
Inside the connector, plated brass contacts help maintain efficient current transmission, while flame-retardant engineering plastic and PPS insulation improve durability and electrical safety. The screw wiring method allows technicians to complete assembly without complex tools, making it suitable for both factory production and on-site installation.Product HighlightsFour-screw square flange for stronger panel fastening Designed for LD32/SP32 heavy-duty waterproof wiring systems 4 pin layout for power distribution and equipment connection IP68 sealed construction for outdoor and wet environments Suitable for thicker cable applications Threaded mating system helps prevent accidental disconnection Screw terminal design supports practical field wiring Durable plastic housing with reliable insulation performance Suitable for industrial equipment, cabinets, and outdoor power systems
Where It Can Be UsedThis connector can be applied to electrical control cabinets, industrial machines, outdoor power boxes, solar equipment, marine electrical systems, large LED installations, charging equipment, automation systems, communication devices, and other equipment requiring a fixed waterproof 4 pin power interface.Manufacturer CapabilityOur factory focuses on connector manufacturing and customized cable connection solutions for industrial and outdoor applications. We provide in-house support for product design, mold development, plastic molding, metal component processing, assembly, testing, and packaging, which helps us maintain better control over product consistency and delivery schedules.
Quality inspection is carried out with dedicated equipment for waterproof sealing, air leakage, insertion and withdrawal force, salt spray resistance, voltage withstand performance, insulation resistance, electrical continuity, and dimensional accuracy. These tests help ensure that each connector is suitable for real working environments rather than only sample display.
The factory operates with a strict quality management system and can support market requirements such as ISO9001, CE, RoHS, UL, BSCI, and high-tech enterprise certification. For project orders, we can also provide customization for cable length, molded cable assemblies, connector color, pin arrangement, mounting structure, labeling, packaging, and other OEM/ODM requirements.
