Total Isolation from Airborne Contaminants
When equipment receptacles are left exposed during storage or operational down-time, the internal socket terminals are vulnerable to fluid ingress and dust buildup. The Y11-2000-81 seals off the entire mating face of the receptacle, keeping the internal electrical pins isolated from sand, moisture, and chemical residues. This reliable protection ensures the connector interface remains dry and fully operational for the next use.
Solid Aluminum Casing and Protective Coating
Constructed from high-strength aluminum alloy, this protective cover delivers superior resistance against physical impacts and crushing forces without adding unnecessary bulk to panel mounts. The exterior shell is treated with a specialized wear-resistant plating that prevents corrosion and mechanical scoring. This ensures that the bayonet locking points engage smoothly and securely over an extended service life.

FAQ
Can this cover be mated with size 20 plug connectors?
Can this cover be mated with size 20 plug connectors?
No. The Y11-2000-81 is specifically designed with dimensions that fit over receptacle connectors. To protect a matching size 20 male plug connector, you will need to source a plug-specific dust cap.
How does the bayonet locking mechanism function on this cap?
How does the bayonet locking mechanism function on this cap?
The cap aligns directly with the external bayonet pins found on the receptacle shell. A simple quick turn securely locks the cover onto the receptacle, preventing accidental detachment during intense vibration.
What is the benefit of the integrated chain lanyard?
What is the benefit of the integrated chain lanyard?
The lanyard acts as a reliable security tether. By fastening the free end of the chain to the equipment panel or chassis, it prevents the cap from getting dropped or misplaced while the connector port is actively used.
Does the Y11-2000-81 protect against fluid exposure?
Does the Y11-2000-81 protect against fluid exposure?
Yes. When properly mated and locked into position, the cap prevents splashing water, grease, and moisture from reaching the sensitive internal electrical contacts, keeping the receptacle fully protected.
