series introduction

# Introduction to the D38999/24FG11PN - LC Product Series

## 1. Overview
The D38999/24FG11PN - LC product series is a high - performance and reliable line of connectors designed to meet the demanding requirements of various industries. These connectors are part of the well - established D38999 family, which is renowned for its ruggedness, durability, and excellent electrical performance.

## 2. Physical Characteristics

### 2.1 Shell Design
- **Material**: The connectors in this series feature a robust metal shell, typically made of high - strength aluminum alloy. This material provides excellent mechanical protection against impacts, vibrations, and harsh environmental conditions. The shell is also corrosion - resistant, ensuring long - term reliability even in outdoor or industrial settings.
- **Finish**: The shell is often finished with a special coating, such as cadmium or zinc - nickel plating. This not only enhances the corrosion resistance but also provides a smooth and aesthetically pleasing appearance.
- **Size and Shape**: The D38999/24FG11PN - LC connectors have a standard circular shape, which is a common design in the aerospace and military industries. The size is optimized to fit into various equipment enclosures and mating connectors, allowing for easy integration into existing systems.

### 2.2 Contact Arrangement
- **Pin and Socket Configuration**: The "24" in the product code indicates the number of contacts in the connector. It has a specific pin - socket arrangement that is carefully designed to ensure proper electrical connection and signal transmission. The pins and sockets are made of high - conductivity materials, such as copper alloy, to minimize resistance and power loss.
- **Contact Density**: With 24 contacts in a relatively compact space, these connectors offer a high contact density. This is beneficial for applications where multiple signals or power lines need to be transmitted within a limited area.

### 2.3 Locking Mechanism
- **Bayonet Lock**: The D38999/24FG11PN - LC connectors are equipped with a bayonet - style locking mechanism. This provides a quick and secure connection between the plug and the receptacle. The bayonet lock ensures that the connection remains stable even under high - vibration or shock conditions, preventing accidental disconnection.

## 3. Electrical Performance

### 3.1 Current Rating
- The connectors are designed to handle a specific current rating, which is determined by the size and material of the contacts. The D38999/24FG11PN - LC series can typically handle moderate to high currents, making them suitable for power distribution and signal transmission applications.
- The current - carrying capacity is carefully calculated to ensure that the connectors do not overheat during normal operation, which helps to maintain the integrity of the electrical connection.

### 3.2 Voltage Rating
- They have a defined voltage rating, which indicates the maximum voltage that the connectors can safely withstand. This rating is important for ensuring the safety and reliability of the electrical system. The D38999/24FG11PN - LC connectors are designed to operate at high voltages, making them suitable for applications in high - power electrical systems.

### 3.3 Insulation Resistance
- High insulation resistance is a key characteristic of these connectors. The insulation materials used between the contacts and the shell have excellent dielectric properties, which prevent electrical leakage and short - circuits. This ensures the integrity of the electrical signals and the safety of the connected equipment.

### 3.4 Signal Transmission
- For signal - transmission applications, the D38999/24FG11PN - LC connectors offer low signal attenuation and high signal integrity. They are capable of transmitting a wide range of signals, including high -
