Protective caps
These caps DBT-W and DST-W resp. are used to protect cable sockets KBT.../...-W and cable plugs KST.../...-W from dust and water when unplugged. Following disconnection, the cap is simply slipped onto the connector. It is removed when connection is remade later on. A cord can be used to attach the cap to the connector’s rubber sleeve or to mounting plate HD-W to keep it from getting lost.
