Color CodedConnectors Urgent Need: Standardized Method to Rapidly Identify High Frequency Coaxial Connectors
High Frequency Coaxial Connector Rapid Identification Difficulty in distinguishing between coaxial connector types results in: • Damaged equipment • Degraded equipment reliability • Degraded performance • Degraded mission readiness • Increasing maintenance time / maintenance actions. • Previously damaged connectors cause damage to mating connectors they are mated with. • Metal particles from connector threads can lodge themselves on or between conduction surfaces. • Damaged connectors need to be discarded to avoid propagation of damage.
High Frequency Coaxial Connector Rapid Identification Why color code? • Just because connectors can mechanically mate together doesn't mean they have the same frequency capabilities. • Difficulty in distinguishing between different coaxial connector types due to the design of high frequency connectors - Resulting in serious risk of damaged equipment, degraded equipment reliability, degraded performance, reduced mission readiness, and lost efficiency.

High Frequency Coaxial Connector Rapid Identification Why is this important? Why is this important? A few things to consider: • Greater Confidence in Connector Identification? • Savings in labor and training costs? • Cost savings (if any) might continue to increase as the use of higher frequencies become more popular? • Efficiency, Reliability and Readiness Improved? • Improved mission readiness? • Improved personnel safety? (i.e. Aircraft Radar etc.) • Simplified writing of procedures involving connectors?
High Frequency Coaxial Connector Rapid Identification Connectors Identified and Colors Chosen: • Black - 0 = 18 GHz - N Type connector • Brown - 1 = 18 GHz - SMA connector • Red - 2 = 20.0 GHz - Precision N Type connector • Orange - 3 = 26.5 GHz - 3.5MM connector • Yellow - 4 = 40 GHz - 2.92mm (K connector ) • Green - 5 = 50 GHz - 2.4mm connector • Blue - 6 = 67 GHz - 1.85mm ( V connector ) • Violet - 7 = 18 GHz - GPC-7 connector • Gray - 8 = < Reserved for future use> • White - 9 = 110 GHz - 1.0mm ( W connector )
