## Summary description

Klauke 670WS is an insulated heat-shrink connector designed for electrical conductors with cross-sections from 0.5 to 1 mm². The connector provides reliable electrical contact and insulated sealing after heat shrinking, protecting joints from moisture and mechanical strain. Suitable for wiring repairs, instrument connections and compact installations where a secure, space-saving connection is needed.

## Long description

Klauke 670WS is an insulated heat-shrink connector designed for electrical conductors with cross-sections from 0.5 to 1 mm². After applying heat the connector forms a compact, sealed joint that ensures stable electrical contact while providing mechanical strain relief and protection against moisture. The slim profile and insulated construction make it suitable for confined spaces and repair work in control panels, instruments and general wiring tasks.
Advantages
The Klauke 670WS offers a combination of reliable conductivity and environmental sealing through its heat-shrinkable tubing and internal conductive element. Installation produces a low-profile joint that reduces bulk in harnesses and panels. Its insulation maintains dielectric separation and reduces the risk of corrosion at the conductor interface. The product is compatible with common hand-held heat sources used for heat-shrinking processes and is designed for consistent shrink performance across the specified conductor range.
Suitable for
Repairing damaged wiring and restoring reliable connections
Connecting instrument and sensor leads in control equipment
Space-limited installations where compact insulated joints are required
Low-voltage signal and power wiring within the stated conductor size range
Key specifications
Conductor cross-section range: 0.5–1 mm²
Insulated heat-shrink design for moisture protection
Low-profile sealed joint after shrinking
Suitable for hand-held heat sources for shrink application
Designed for electrical continuity and mechanical strain relief
How to use
Prepare the conductors by stripping appropriate lengths of insulation to expose clean conductor ends. Insert the conductors into the connector so that the conductive element makes firm contact with both wires. Apply heat evenly around the connector using a suitable heat source until the tubing shrinks and conforms tightly around the conductors; continue heating until the internal material forms a sealed, uniform joint. Allow the connector to cool before handling to ensure the shrink and seal have fully set.
Usage recommendations
Use a temperature-controlled heat gun or equivalent heat source and follow safety precautions for heat-shrinking. Avoid excessive localized heating that could damage nearby insulation or components. For critical applications, verify continuity and insulation resistance after installation to confirm a proper electrical and sealed connection.
