Connector Specification:
A dummy receptacle is a non-electrical insert that protects a connector’s interface when it’s not in use. It shields the shell and threads from dust, moisture, and damage, maintaining the environmental seal and alignment for future connections.
Pick a dummy that matches your connector series, size, and mounting style. Check these points:
Tip: If unsure, compare shell code and thread size, or contact EMCA for a quick match.
No. Dummy receptacles are mechanical only — they contain no contacts and do not carry current or signals. They’re for protection, not electrical use.
It usually improves performance by protecting critical surfaces. Problems only occur if the dummy is poorly fitted or not sealed properly, which can trap moisture or cause wear over time.
Yes, if the connector isn’t used electrically and the dummy meets all mechanical and environmental needs. Periodic inspection is still advised for long-term reliability.
Common references include MIL-DTL-38999, VG96912, VG95328, and JN1003 specifications. These define shell dimensions, threads, and sealing requirements. EMCA lists the compatible standard on each product page.
