Perfexim screw connector 703 16 mm for cable joining, model 61-003-0160-000

Perfexim screw connector 703 with 16 mm diameter (model 61-003-0160-000) is a compact mechanical and electrical joining fitting designed to join cable conductors by screw tightening. The connector secures single-core or multi-core cable ends of compatible cross-section, providing a reusable mechanical joint for installations, repairs and cable extensions where a reliable conductive connection is required.

Advantages

The screw connector provides a stable mechanical clamp that maintains conductor contact under normal vibration and handling. Its compact cylindrical form factor allows use in confined spaces while enabling quick installation without specialized tools beyond a suitable screwdriver. The design supports repeated disassembly and reassembly for maintenance or reconfiguration and is suitable for a range of common copper conductor types when matched by cross-section.

Suitable for

• Joining single-core or multi-core copper cables with matching cross-section
• Electrical repairs and cable extensions in building installations
• Temporary or semi-permanent connections in control panels and junction boxes
• On-site refurbishment where reusable mechanical connectors are preferred

Key specifications

• Connector type: screw-tightened mechanical cable connector
• Nominal diameter: 16 mm (connector body diameter)
• Compatibility: for conductors of matching cross-section (single-core or multi-core)
• Material: conductive metal body with threaded screw clamp (metallic contact parts)
• Mounting: inline joining of conductor ends by screw torque
• Reusability: designed for multiple assembly/disassembly cycles

How to use

Strip insulation from cable ends to the appropriate length so that bare conductors fully enter the connector body without exposed strands outside the clamp region. Insert the prepared conductor ends into the opposite openings of the screw connector, then tighten the central screw(s) evenly with a suitable screwdriver until the conductors are firmly held. Verify mechanical retention by a gentle pull test and ensure there is continuous electrical contact. If necessary, re-tighten to the torque appropriate for the conductor cross-section; avoid over-tightening that could damage conductors.

Usage recommendations

Use the connector only with conductors of suitable cross-section and material; do not use with conductors that exceed the connector's intended size or with dissimilar metals without appropriate treatment. Where the installation is exposed to moisture or corrosive atmosphere, provide additional protection such as insulating tape, heat-shrink tubing or sealed junction boxes. Follow local electrical codes for conductor preparation, torque values and insulation clearance.
