MIL-DTL-26482 Series II Connectors
These connectors were commonly used in military and aerospace applications. But now these connectors are used in a wide array of commercial as well as industrial applications such as lighting, sensors, power generators, hydraulic systems, transportation, medical equipment, advanced scientific applications to name a few.
The MIL-DTL-26482 II connectors have a robust construction and are resistant to shock, vibration, or environmental hazards such as moisture and dust. Capable of carrying high currents and voltage levels, the 26482 Series II Connectors are a durable and reliable connection option where high performance and ruggedness is a critical requirement.
Available in shell sizes ranging from 8 to 24 and insert arrangements of up to 61 pins, these connectors have a bayonet coupling mechanism which helps in quick and secure mating.
