These connectors are thread coupled and are in conformity
to operating requirements of MIL C 5015 specifications for various industrial
applications and are used in both military and commercial applications. MIL-C-5015 are the most popular of all cylindrical connectors for general use in electronic interconnection systems. These connectors are known for their supreme reliability, high power carrying capacity, their inherent ruggedness and capacity to withstand extreme environmental conditions. Typical circular connectors have pins mounted into an insert within the connectors. Disposed around the insert is a movable coupling nut which can be twisted to allow the coupling nut to threadedly engage the mating receptacle connector.
Different insert layouts as per MIL STD
1651A and different contact sizes allow carrying of current upto 150 amps. The
standard MIL C 5015 insert layouts permit mixing of power and signal contacts.
