LD24/SP24 Waterproof In-line Cable 4 Pins Connector Overview

The LD24/SP24 Waterproof In-line Cable 4 Pins Connector is designed for applications requiring robust mechanical strength and dependable power transmission. Its larger housing and reinforced construction make it a practical choice for heavy-duty equipment where consistent performance under demanding conditions is essential.

SP20 Connector

The precise docking interface ensures accurate alignment and secure mating, contributing to stable electrical performance in challenging industrial settings.

Key Selection Criteria for the LD24/SP24 Series

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

  • Structural Capacity: The larger size offers enhanced mechanical strength compared to smaller series, suitable for equipment exposed to vibration and impact.
  • Power Delivery: The 4-pin configuration is optimized for stable power transmission, supporting reliable system operation.
  • Mating Security: The docking mechanism promotes firm engagement, reducing the risk of poor contact during operation.
  • Environmental Protection: The sealed design helps resist water and dust ingress, supporting use in outdoor or harsh environments.
  • Mechanical Resilience: Engineered to maintain connection integrity under mechanical stress and continuous movement.

Construction and Material Considerations

The connector's housing is available in PC or Nylon66, offering a balance of durability and weight. The cores are made of brass plated with gold, ensuring good conductivity and corrosion resistance. The insulator material is PPS, which provides stable performance across a range of operating temperatures. These material choices contribute to the connector's suitability for industrial applications.

LD24 Connector

Manufacturing and Quality Assurance

Our manufacturing process integrates die-casting, mold development, machining, injection molding, and assembly in-house. This vertical integration supports consistent quality control. Each connector undergoes testing for electrical performance, mechanical durability, and environmental resistance before delivery.

SP20 Connector

We also offer customization services, including adjustments to pin layout, materials, and other application-specific requirements.

Circular Connector

Suitable Applications and Boundaries

This connector is well-suited for heavy industrial equipment, power supply systems, automation machinery, outdoor energy equipment, and electrical control systems. It is designed for applications with high reliability requirements.

However, it is not intended for applications requiring high-frequency signal transmission or where space constraints demand a more compact connector. For those needs, consider other series within our product range.

Connector

Information Needed for Accurate Selection

To ensure the correct configuration for your project, please provide the following details when making an inquiry:

  • Mating-side requirement (plug or socket, male or female)
  • Pinout or wiring diagram
  • Cable outside diameter and conductor size
  • Electrical load (current and voltage)
  • Operating environment (temperature, exposure to moisture or chemicals)
  • Required order quantity
