Performance and Specifications
The 5.5mm outer / 2.1mm inner format is the industry standard for consumer electronics and surveillance systems. If you aren’t sure which connector you need, this is almost certainly the one. With a rated voltage of 30V DC, you have a comfortable margin above standard 12V requirements. The 3N insertion force ensures a firm, secure connection that won’t pull out accidentally, while the corrosion-resistant contacts prevent oxidation over time.

Frequently Asked Questions
What is the difference between a 5.5×2.1mm and a 5.5×2.5mm connector?
It is a subtle 0.4mm difference, but it is critical. The inner pin is 2.1mm versus 2.5mm, and they are not interchangeable. Please check your adapter or camera specifications before ordering.
Can I use these for 19V or 24V, or only 12V?
Yes. These are rated for up to 30V DC, so they work perfectly with 12V, 19V, or 24V systems, provided the current does not exceed 10A.
Do I need a soldering iron to install these?
No soldering is required. These female jacks feature screw terminals; simply insert the wire, tighten the screw, and you are done. Installation takes less than 2 minutes with a small screwdriver.
Are these compatible with standard security cameras?
Yes. The 5.5×2.1mm size is the most common connector used in CCTV systems and 12V IP cameras. This 5-piece set is ideal for new installations or replacing damaged connectors on existing equipment.
