Fischer Connectors Core Series Rugged Precision Circular Connectors for Military Aerospace and Medical Systems

The Fischer Core Series is the connector line designed for the defense systems integrator who needs a precision circular connector meeting the electrical and environmental requirements of MIL-DTL-38999 Series III — the NATO reference standard for aviation and defense system connectors — but with a faster and more compact locking design than the standard trilobular bayonet, because operators under tactical stress need to connect and disconnect equipment with gloves in under one second without risk of incorrect connection.

Fischer's patented push-pull locking mechanism — where the operator simply pushes the male connector against the female until hearing the locking click, and disconnects by pulling on the outer ring without twisting — reduces connection time under thick-glove conditions from the 4 to 6 seconds of the standard bayonet to under 1 second, eliminating partial connection failures that occur when the bayonet is not fully turned, which are the most frequent cause of electronic equipment failure in high-activity tactical operations.

The 316L stainless steel body material — the same alloy used in surgical implants and food processing equipment — guarantees corrosion resistance in saltwater environments, Amazon jungle river immersion with low pH, and exposure to military fuels and lubricants defined in MIL-PRF-5606 and MIL-PRF-83282, without the galvanic corrosion problems affecting anodized aluminum connectors in contact with stainless steel in marine environments.
