DC 099 Power Cable

DC 099 Power Cable

The DC-099 Power Cable is a panel-mount DC power connector assembly featuring a threaded female jack with pre-attached pigtail wires, designed for secure, waterproof power connections in electronic devices. Commonly using the standard 5.5mm x 2.1mm or 5.5mm x 2.5mm barrel plug size, these connectors provide a reliable power input interface for equipment requiring a durable, locking power connection. The threaded coupling ensures the mating plug stays securely connected even under vibration or accidental tugging, while the integrated sealing ring provides water resistance for outdoor or industrial applications. Available with various wire lengths, gauges, and termination options, DC-099 cables offer a clean, professional power input solution for custom enclosures, industrial equipment, and consumer electronics.

Star Reviews From Customers

 

1.Dave, industrial controls guy in Ohio
"Been using these DC-099 cables on our PLC panels for years. The threaded lock keeps the power plug from vibrating loose-had issues with barrel jacks falling out before. The pre-wired pigtails save time in assembly. Only complaint is the nut could be a bit wider for a better grip when tightening."


2.Carlos, security system integrator in Mexico
"Deployed these on outdoor cameras in a casino parking lot. Been running 24/7 for 18 months now, no issues. The 5.5 x 2.1mm size matches most power supplies. The 20 AWG wire is a bit thin for longer runs, we order the 18 AWG version for anything over 10ft."


3.Wei, electronics manufacturer in Shenzhen
"We use these on our portable power stations. Quality is consistent across batches-good solder joints, proper insulation. The 2.1mm center pin version is our standard. Delivery times have been reliable. Would recommend."


4.Alex, e-bike conversion guy in Germany
"Using the 5.5 x 2.5mm version for charging port on my custom battery box. The larger center pin handles 8A charging without heating up. The threaded lock is secure-no wobble like standard barrel jacks. The included washer and nut make mounting easy."


5.Lisa, lab equipment manager in Canada
"Standardized on these for all our custom test fixtures. The pre-wired pigtails with spade terminals at the other end make wiring to terminal blocks quick. The 20 AWG is fine for signal gear. The waterproofing is a bonus for our wash down areas."
