SD20/SP20 Square Flange Connector Design and Installation Guide

SP29 Electrical Flange Connector Overview

The SP29 electrical flange connector is a large-size industrial circular connector designed for high-reliability power and signal connections in demanding environments. With a reinforced flange mounting structure and robust housing design, it provides secure installation and stable electrical performance for heavy-duty equipment and outdoor systems.

This connector is available in multiple pin configurations from 2 to 26 pins, allowing flexible integration into complex electrical systems that require multi-circuit connections. Its larger contact capacity and strong mechanical structure make it suitable for applications where durability, safety, and long-term reliability are critical.

Built for Heavy-Duty Electrical Applications

Compared with smaller connector series, the SP29 connector is engineered to handle higher load requirements and more complex wiring configurations. The flange mounting design ensures firm attachment to equipment panels, reducing movement and improving connection stability during operation.

Key functional characteristics include:

• Heavy-duty flange mounting structure
• IP67 / IP68 waterproof and dustproof protection
• High mechanical strength for industrial environments
• Stable power and signal transmission
• Reliable performance under vibration and outdoor conditions

Flexible Engineering & Configuration Options

The SP29 flange connector is designed to support a wide range of electrical and mechanical installation requirements:

• Multiple pin options: 2 - 26 Pins
• Panel mount flange installation structure
• Solder or crimp termination types
• Compatibility with larger cable diameters
• Optional protective caps and sealing accessories
• OEM customization for mechanical design and branding

This flexibility makes the connector suitable for both standard industrial equipment and customized system integration projects.
