There are different types of plugs. When do I use which one?

There are different standards for plugs and jacks:

  • IEC 60603-11
  • EIA RS-453
  • BPO 316
  • MIL-P-642, MIL-J-641

Neutrik’s Standard ¼” Phone Plugs (A-Gauge) fulfill both, the IEC and EIA-Standard by using tighter tolerances and offering a special type for the MIL and the BPO-standard. (Longframe ¼” – TB type)

Some applications for the different types are:

  • ¼” Professional Phone Plugs (Longframe A-Gauge) NP*C --> Consumer range like Guitars, Headphones (most common)
  • MIL / B-Gauge (Longframe B-Gauge) NP3TB --> Professional broadcast and audio range, patch panels
  • Bantam Types NP3TT --> patch panels
