DC Power Socket DC-005C 3.5×1.35mm 3-Pin

DC-005C 3.5×1.35mm 3-Pin Female DC Power Socket

The DC-005C 3.5×1.35mm Female DC Power Socket is a compact electrical connector designed for supplying DC power to electronic circuits, portable devices and small electronic equipment.

It features a right-angle housing with three metal solder terminals, making it suitable for circuit board installation, electronic repairs and custom power input connections.

The DC-005C also includes an integrated switching contact, allowing circuits to detect or respond to the insertion of an external DC power plug.

Key Features

• 3.5×1.35mm Connector: Designed for compatible miniature DC barrel plugs with a 3.5mm outer diameter and 1.35mm inner diameter.
• 3-Pin Configuration: Provides the main positive and negative contacts plus an additional switched terminal.
• Right-Angle Design: Horizontal socket orientation makes it suitable for compact electronic circuit boards.
• Switched Contact: Supports applications where inserting an external power adapter disconnects an internal power connection.
• Solder Terminals: Three metal terminals with holes for soldering wires or installation in suitable circuit boards.
• Compact Housing: Black insulated construction suitable for electronics with limited installation space.

Technical Specifications

Applications

1. Electronic Equipment Repairs

Replace damaged or loose DC input sockets in compatible portable electronics, small radios, audio equipment and rechargeable electronic devices.

2. DIY Electronics Projects

Create an external DC power input for small custom circuits, control boards and electronics prototypes that use a 3.5×1.35mm barrel connector.

3. Battery-Powered Electronics

The third terminal provides a switched connection that can be used to disconnect an internal battery supply when an external DC plug is inserted, depending on the circuit design.

4. Small Audio Devices

Suitable for replacing compatible DC input sockets in portable speakers, small amplifiers and other low-voltage audio equipment.

5. Electronic Prototyping and STEM Projects

Useful for learning about DC connector wiring, power supply polarity, switched contacts and circuit construction.

Understanding the 3-Pin Connection

The DC-005C has three terminals with different electrical functions:

1. Centre Contact: Connects to the centre conductor of the inserted DC barrel plug.
2. Outer Contact: Connects to the outer sleeve of the DC barrel plug.
3. Switched Contact: Provides an additional connection that changes state when a compatible plug is inserted.

The switched contact can be used in circuits that alternate between battery power and external DC input.

Before soldering, use a multimeter in continuity mode to identify the terminal connections with the plug inserted and removed.

For electrical testing, DIYGH stocks the ANENG XL830L Digital Multimeter, suitable for checking continuity, polarity and DC voltage.

Important Connector Compatibility

The DC-005C accepts 3.5×1.35mm male barrel plugs.

It is physically different from the larger 5.5×2.1mm DC connector commonly used in Arduino development boards, CCTV systems and power adapters.

If your project uses a 5.5×2.1mm connector, DIYGH also stocks the 5.5×2.1mm Threaded Female DC Power Socket.

For installations requiring a larger connector with wires already attached, see the Prewired Female DC Power Socket.

Installation Guidelines

1. Confirm that the mating DC plug measures 3.5×1.35mm.
2. Identify the three terminals using a multimeter.
3. Mount the socket securely on a compatible circuit board or solder the required wires to its terminals.
4. Check the power adapter’s output voltage and polarity.
5. Insulate exposed connections where necessary.
6. Verify the completed circuit before connecting power.

Note: This socket is a DC power connector, not a battery charging controller. Charging rechargeable batteries requires a suitable charging circuit.
