## Long description

Earthing contact plug MACLEAN MCE330 is a compact grounding contact adapter designed to provide a reliable earth reference for equipment using RJ-style connectors. The adapter inserts into standard RJ connector housings and establishes a conductive path between connector shielding or dedicated earth conductors and a grounding point, helping to reduce electrostatic disturbances and improve electromagnetic compatibility in networking and telecommunications setups.
Advantages
The MACLEAN MCE330 contact plug offers a compact form factor that fits into standard RJ connector assemblies without modifying existing connector housings. Its conductive contact provides a low-resistance path for shielding and earth conductors, enhancing protection against static charges and minimizing interference. The adapter is suitable for installations where a dedicated grounding point is required but space is limited, and it enables standardized earthing practice across patch panels, wall jacks, and equipment ports.
Suitable for
 Ethernet patch panels and keystone jacks where connector shielding needs grounding
 Telecom equipment and network switches requiring an external earth reference
 Installations in server rooms and communication cabinets to improve EMC performance
 Retrofit projects where existing RJ connectors lack a built-in grounding contact
Key specifications
 Form factor: Compact contact plug compatible with standard RJ-style connector housings
 Function: Provides conductive connection between connector shielding/earth conductor and grounding point
 Material properties: Conductive contact surface designed for stable electrical continuity
 Mounting: Inserts into RJ connector aperture without permanent modification to the connector housing
 Application environment: Intended for networking and telecommunications equipment and installations
How to use
Insert the earthing contact plug into the RJ connector housing at the location designated for the shielding contact or into a compatible aperture in the connector assembly. Ensure the contact makes firm mechanical and electrical contact with the connector shield or the designated conductor. Route the adapter's grounding lead or contact to the facility grounding point or chassis earth and secure according to site grounding practices. Verify continuity between the connector shield and the grounding point using an appropriate tester before placing equipment into service.
Usage recommendations
Use the MACLEAN MCE330 in accordance with local grounding and grounding conductor installation standards. Confirm compatibility with the specific RJ connector housing and test electrical continuity after installation. Avoid using the adapter in environments where mechanical strain or exposure to corrosive substances could compromise the conductive contact.
