MCDC12F MICRO WET DUMMY CONNECTOR 12 Pins Underwater Dummy Plug Female

MCDC12F Micro Circular Dummy Connector — 12 Contacts

The MCDC12F is a 12-contact Micro Circular dummy connector in the female (sockets) configuration. It is not an electrical part: it seals and protects an unmated 12-contact Micro Circular connector against seawater ingress, biofouling, grit and mechanical damage during storage, transit and service intervals.

12 Contacts Dummy Connector Female Version 7,000 m Depth Chloroprene Body IP68

Key Design Features

• Keyed to the shell: the dummy carries the same keyway and thread as the working connector, so it cannot be fitted to the wrong contact count.
• Same seal as the connector: the nitrile O-ring compresses against the same sealing face, keeping the unmated contacts dry.
• Chloroprene body: the same rubber as the connector body, tolerant of deck handling, UV and the full operating temperature range.
• Protects the wet-mate life: keeping the per-contact seals compressed and the bores clean is what preserves the 500-cycle rating of the working connector.
• Correct pairing: the F version covers male connectors, the M version covers female connectors.

Protecting unmated 12-contact ports on multi-bus instrument packages and tether panels.

Notes for Selection

Keep a dummy on every spare port: an open 12-contact face is the most common entry point for water in a breakout panel.
