LD16/SP16 2 Pin 2-Hole Flange Mount Waterproof Connector

LD16/SP16 Flange Connector Dimensions and Materials

LD16/SP16 2 Pin 2-Hole Flange Mount Connector Overview

The LD16/SP16 2 Pin 2-Hole Flange Mount Connector provides a fixed, waterproof power connection point for equipment housings and panels. Its compact body suits products with limited installation space, including lighting fixtures, control boxes, outdoor instruments, and small electrical equipment.

The 2-hole flange base mounts directly onto a panel with screws, offering greater stability than a free-hanging cable connector. A threaded locking structure keeps the male and female parts tightly connected, reducing the risk of loosening from vibration or movement.

Electrical and Mechanical Specifications

The 2-pin configuration is commonly used for power input and output. It supports 20A rated current and 250V AC rated voltage, making it suitable for medium-power electrical applications. The connector accepts cables with an outer diameter of 4-8 mm, offering a practical solution for compact waterproof cable assemblies.

The housing is made from flame-retardant engineering plastic, while the internal contact parts use brass with plated surface treatment for stable electrical contact. Screw wiring makes assembly straightforward and helps installers complete wiring without complicated tools.

Key Selection Considerations

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

• Mounting requirement: The 2-hole flange design is intended for panel or housing mounting; confirm your panel thickness and hole spacing match the flange dimensions.
• Environmental exposure: The IP68 waterproof design suits environments where rain, dust, moisture, or water splashing may occur, but confirm the mating pair is fully engaged for rated protection.
• Electrical load: Verify your operating current and voltage stay within the 20A / 250V AC rating, including inrush and continuous load conditions.
• Cable compatibility: The 4-8 mm cable outer diameter range determines which cable types can be terminated; confirm your cable fits before ordering.
• Mating side: Specify whether you need a male or female flange connector and confirm the corresponding plug configuration for your assembly.
