Part Number Breakdown
Common Type "AN" Cannon Plug Connectors
  |
AN3100A Wall Mounting - Receptacle Type AN3100A wall mounting receptacles (Type RA) are used with conduit to eliminate the need for a conduit box in applications where wires are carried through walls or bulkheads. Mate with AN3106B, AN3107B, and AN3108B plugs. |
  |
AN3101B Cable Connecting - Receptacle Type AN3101B cable connecting receptacles (Type RP) are used for cable extension requirements where mounting provisions are unnecessary. Mate with AN3106B, AN3107B, and AN3108B plugs. |
  |
AN3102A Box Mounting - Receptacle Type AN3102A box mounting receptacles (Type RB) are used in shielding boxes or as a part of the equipment. Mate with AN3106B, AN3107B, and AN3108B plugs. |
 |
AN3106B Straight - Plug Type AN3106B straight plugs (Type RA) are used to connect circuits with standard receptacles. Mate with AN3100A, AN3101B, and AN3102A. |
  |
AN3107B Quick Disconnect - Plug Type AN3107B special quick disconnect plugs (Type PC) are used on equipment demanding unusually quick disconnection for emergency conditions or reasons of safety, but are not adaptable to vibration conditions. Mate with AN3100A, AN3101B, and AN3102A receptacles. |
 |
AN3108B Angle 90° - Plug Type AN3108B angle 90° plugs (Type PB) are used for installations having limited space or where wires must be brought off at abrupt angles. Mate with AN3100A, AN3101B, and AN3102A receptacles. |
Cannon Plug Contact Types
 Type S - Socket Contact Type S socket contacts are designed to mate with Type P pin style contacts in the front, and are constructed with a solder cup in the back that will not leak through the front of the socket and prevent insertion of the pin contact. |
 Type P - Pin Contact Type P pin contacts mate with the corresponding socket contact and are designed to resist severe vibration and repeated connections and disconnections encountered in service. |
