with crimp sleeve
Plugs KST.../...-W are the rigid-pin plugs used for watertight connections. They are designed for crimp connection of highly flexible Cu conductors with cross-sections between 25mm˛ and 95mm˛. The mating sockets for these plugs are sockets KBT.../...-W with corresponding contact diameter. The rubber sleeve has a snap-in ring that engages with a corresponding groove when the plug is plugged into the socket (to prevent inadvertent disconnection). The pull required for disconnection can be increased by shifting the locking ring over the snap-in lock.
