DC power connector electro base AD-DC-F-PROFI 5.5×2.1 mm male for 12V/24V

Electro base AD-DC-F-PROFI 5.5×2.1 mm male is a DC power connector designed for reliable low-voltage power delivery in 12V and 24V systems. The connector provides a secure, standardized plug interface compatible with many CCTV cameras, LED drivers, routers and small electronic devices. Its compact cylindrical design ensures straightforward installation and replacement in power cabling for consumer and professional low-voltage equipment.

Advantages

The connector offers a robust mechanical fit and stable electrical contact for continuous low-voltage operation. Its 5.5×2.1 mm dimensions follow common DC barrel standards, ensuring wide compatibility with power adapters and device sockets. The male construction facilitates simple plug-in connections while the metallic contact surfaces and insulated housing reduce the risk of short circuits and provide consistent conductivity over repeated use.

Suitable for

• CCTV cameras and surveillance systems
• LED drivers and lighting strips
• Network equipment such as routers and switches
• Small consumer electronics and low-voltage power supplies
• Repair and replacement of existing DC power leads

Key specifications

• Contact configuration: male DC barrel connector
• Outer diameter: 5.5 mm
• Inner pin diameter: 2.1 mm
• Rated voltage: compatible with 12 V and 24 V systems
• Intended use: low-voltage DC power connections
• Housing material: insulated plastic with metal contacts
• Connection method: plug-type mating with corresponding female socket

How to use

Prepare the cable by stripping the insulation to expose the conductor lengths required by the connector. Insert and secure conductors according to the connector's wiring terminals or solder points, ensuring correct polarity for 12V/24V systems. After assembly, test the connection with a suitable power source to verify stable contact and correct voltage before final installation. When connecting to equipment, align the male barrel with the device's female socket and push in until a secure fit is achieved.

Usage recommendations

Verify polarity and voltage compatibility before connecting to devices; use for 12V or 24V low-voltage circuits only. Avoid exposing the connector to prolonged moisture or mechanical strain. For installations subject to vibration or movement, ensure strain relief and secure cable routing to maintain reliable contacts over time.
