DC plug adapter Exsys EX-49140 5.5×2.1 mm to 2-pin terminal block, 15 cm cable

The Exsys EX-49140 is a reliable DC plug adapter designed to bridge the gap between standard power supplies and custom wiring setups. Featuring a 5.5x2.1 mm male barrel connector on one end and a convenient 2-pin terminal block with a push-button mechanism on the other, this adapter is connected by a 15 cm cable to offer flexible positioning. It provides a straightforward and solderless solution for connecting devices that use a barrel DC jack to bare wires or equipment equipped with terminal blocks.

Advantages

This adapter simplifies power management by eliminating the need for complex soldering or permanent cable modification when connecting power sources to electronic devices. The integrated push-button terminal block allows for quick and secure insertion and release of stripped wires, saving time during installation and maintenance. With a compact 15 cm cable length, it reduces strain on connectors and provides just enough reach to accommodate tight spaces in control panels or behind equipment. The sturdy build quality ensures a stable electrical connection for daily low-voltage power transmission.

Suitable for

• Connecting power supplies to CCTV security cameras and surveillance equipment
• Setting up custom low-voltage power distribution in electronics projects
• Testing and prototyping circuits on testbenches
• Powering small electronic devices, LED lighting strips, and single-board computers

When it may not be suitable

This adapter is not designed for high-current industrial power applications or environments exceeding standard low-voltage DC ratings. It is also unsuitable for applications requiring waterproof connections or heavy-duty mechanical strain relief.

Key specifications

• Connector type A: DC male barrel plug 5.5x2.1 mm
• Connector type B: 2-pin terminal block with push-button mechanism
• Cable length: 15 cm

How to use

To use the adapter, simply insert the 5.5x2.1 mm DC plug into the compatible power source or device jack. Press down on the push-button mechanism of the 2-pin terminal block to open the contacts, insert the stripped ends of your bare wires into the ports, and release the button to secure the connection firmly. Ensure that polarity is correctly matched between the power source and the connected wires before turning on the power.

What to consider before purchase

• Verify that your device requires a 5.5x2.1 mm DC barrel connector size.
• Check the electrical current and voltage requirements of your equipment to ensure compatibility.
• Measure the required distance to confirm whether the 15 cm cable length meets your setup needs.

Usage recommendations: Always double-check the positive and negative wire polarity before connecting power to prevent potential damage to your electronic equipment. Ensure that the stripped wire ends are inserted securely into the terminal block to maintain a stable and safe electrical contact.
