SKU CH-D503-QTSPD

A 7 × 4 mm male DC power plug for CCTV and standard devices, featuring a 50 mm total length and solder-cable connection

  • TypeHI - Power Plugs & Connectors
  • Reliable power delivery via precision-machined contacts
  • Quick solder-ready design speeds up cable assembly
  • Compact 50 mm length fits tight enclosures
  • Durable metal and plastic housing resists wear
  • Lightweight 5 g construction adds minimal bulk

Ideal Replacement for DC Power Jacks

This straight-blade plug serves as a direct replacement for a worn or damaged power-supply jack on standard DC devices. It suits installers and hobbyists who need a reliable connector for CCTV cameras or similar low-voltage equipment. The male design mates with common barrel sockets for quick restoration of power.

Solder-Ready Connection Changes Installation Method

The plug requires a soldered cable attachment, which creates a permanent and mechanically strong joint compared with screw-terminal alternatives. This approach reduces the risk of loose wires in vibration-prone environments such as vehicle-mounted cameras. The single-unit package means each connection point needs its own plug.

Physical Dimensions Define Compatibility Limits

Total length measures 50 mm with a 9 mm shaft, so the connector fits only jacks that accept those exact proportions. The mixed metal and plastic construction in black, yellow and silver tone offers basic durability but no weather-sealing rating. Users must verify socket depth and polarity before soldering to avoid mismatched connections.

Questions about this item

How do I replace the cable on this 7 x 4 mm DC male plug?

The plug is designed for soldered cable connections, so you would desolder the old cable and solder a new one to the terminals.

What limits how long this connector can run continuously?

The metal and plastic construction handles typical DC power loads, but the 9 mm shaft and solder joints set the practical thermal and mechanical limits.

Does this straight blade plug get hot or draw extra power when used all day?

As a passive connector it adds no power draw, and heat depends only on the current passing through the 5 g metal contacts.
