LD32/SP32 4 Pin Square 4-Hole Flange Connector IP68 Waterproof

For equipment requiring a fixed waterproof power interface, the LD32/SP32 4 Pin Square 4-Hole Flange Connector provides a robust panel-mount solution. It is engineered for larger cables, higher electrical loads, and installations where the connector must remain securely mounted to the enclosure during long-term operation.

The square flange base, secured with four screws, delivers strong mounting integrity on control cabinets, distribution boxes, machinery panels, outdoor enclosures, and power equipment. This design is particularly beneficial in applications subject to cable strain, vibration, frequent maintenance, or repeated mating cycles.

Selection and Application Fit

With a 4-pin configuration, this model supports multi-core power wiring in industrial and outdoor systems. The LD32/SP32 size accommodates thicker cable assemblies and provides ample space for stable wiring, making it a suitable upgrade from compact waterproof series when higher power capacity is required.

• Mounting: Four-screw square flange for secure panel fastening
• Sealing: IP68-rated construction for outdoor and wet environments
• Mating: Threaded coupling system helps prevent accidental disconnection
• Termination: Screw terminal design supports practical field wiring
• Construction: Durable plastic housing with reliable insulation performance

Construction and Reliability

The connector employs an IP68 sealing structure to minimize the risk of water, dust, and humidity affecting the electrical contact area. Once the mating side is tightened, the threaded connection creates a firm lock between plug and socket, supporting safer operation in demanding environments.

Internally, plated brass contacts help maintain efficient current transmission, while flame-retardant engineering plastic and PPS insulation enhance 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.

Typical Applications

This connector is applicable to electrical control cabinets, industrial machinery, outdoor power boxes, solar equipment, marine electrical systems, large LED installations, charging equipment, automation systems, and communication devices requiring a fixed waterproof 4-pin power interface.

Quality Assurance and Customization

Our factory specializes in 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, ensuring better control over product consistency and delivery schedules.

Quality inspection is performed using 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 each connector is suitable for real working environments.

The factory operates under a strict quality management system and supports market requirements such as ISO9001, CE, RoHS, UL, BSCI, and high-tech enterprise certification. For project orders, customization is available for cable length, molded cable assemblies, connector color, pin arrangement, mounting structure, labeling, packaging, and other OEM/ODM requirements.

Selection Considerations and Inquiry Checklist

When evaluating this connector for your application, consider the following factors:

• Mating side: Confirm whether you need a plug, socket, or complete cable assembly
• Cable specifications: Provide cable outside diameter and conductor size for proper fit
• Electrical load: Specify operating current and voltage requirements
• Environmental conditions: Detail exposure to water, dust, chemicals, or temperature extremes
• Order quantity: Indicate volume for production planning and lead time

For detailed dimensional data and material specifications, refer to the LD32/SP32 Square Flange Connector Dimensions and Materials. For application-specific guidance, see this LD32/SP32 Square Flange Connector for Semiconductor Equipment case study.

To ensure correct matching, please provide your mating-side requirement, pinout or drawing, cable outside diameter, conductor size, electrical load, environment, and order quantity when submitting an inquiry.
