Cable blanking kit
Cable blanking kit CH-4PFMBLANK has a male part and female part, each of these is used with the opposite end of standard 4 pin cables to blank the exposed connection, preventing dirt and water from affecting the contacts.
These are only required where standard 4 pin cables are being used in a disconnect situation such as on some caravan camera systems and can also be used on lift-off canopy connections which have a 2 piece cable to allow removal.
These are the same as the extension cable connections but just fully moulded plastic without any cable. The plastic end is long enough to allow a hole to be drilled if these need to be kept on a lanyard or similar.
