Front connector for S7-300 signal modules
The 6ES7392-1AJ00-0AA0WMR/U6 is a 20-pole front connector with screw terminals, designed for SIMATIC S7-300 signal modules that use screw-type termination. It mates with the module's front interface and carries up to two conductors per screw clamp (1.5 mm² total in a shared ferrule). This is a used component, so verify condition upon receipt.
Mounting and wiring
The connector plugs into the S7-300 module's front slot and locks with the side latches. Screw clamps accept solid or stranded wire; for two conductors up to 1.5 mm² each, use a shared ferrule. Dimensions 131 x 23 x 36 mm fit the standard S7-300 module envelope. Operating temperature 0…60 °C.
