MS3116F18-32P is a straight plug connector from the Amphenol MIL-DTL-26482 Series I, designed for high-density circular connector applications requiring robust environmental sealing. The connector features an 18-contact shell size with an F-type environmental endbell without clamp, providing protection in demanding industrial and military environments. It utilizes a bayonet coupling mechanism for quick-disconnect mating and unmating, with an aluminum alloy shell and hardware construction that minimizes weight while maintaining ruggedness. The connector is intermateable with ITT Cannon and Souriau MIL-DTL-26482 connectors, making it suitable for power generators, off-road vehicles, industrial machinery, engines, earth-moving equipment, telecommunications, sensors, ships, and motion control applications where reliable high-density interconnection is essential.
