ADJ Accu-Cable 3-Pin DMX Cable Spool 300'

The ADJ AC3CDMX300 is a 300 foot spool of 3-pin DMX cable created for lighting professionals who want to build custom-length runs without compromising signal quality. Whether you are wiring a permanent installation in a theater or assembling a portable rig for touring shows, this spool lets you pull exactly the amount of cable you need and terminate it with DMX512 XLR connectors on your schedule.

Inside, you will find 22 AWG conductors made from stranded tinned copper that keep resistance low while remaining easy to solder. A polyethylene inner jacket separates the conductors and maintains consistent geometry, which is vital for data integrity. Surrounding that core is a Duofoil shield with full 100 percent coverage, followed by an 85 percent tinned copper braid. This two-stage shielding blocks electromagnetic interference so lighting cues arrive precisely when they should.

The outer jacket uses PVC that stays flexible in temperatures ranging from minus 22 to 167 degrees Fahrenheit. That pliability, combined with a maximum tensile load rating of 72 pounds, allows the cable to endure tough pulls through conduit, truss, or wall cavities without kinking or tearing.

Because the cable is tuned to a nominal impedance of 110 ohms, it meets the electrical requirements of the DMX512 protocol. The result is reliable data transmission over long distances, making the spool a practical choice for houses of worship, clubs, broadcast studios, and any venue where stable lighting control is critical.
