Screw Wiring
E-Weichat Screw wiring series
The conventional round lockwire series can protect installed equipment even when used in a water-containing environment. The Weichat connector boasts IP68 waterproofing, effectively preventing moisture from infiltrating through cables, water vapor, surface drips, and water impacts. It can be used to install equipment and power it in areas with a water depth of up to 4 meters, ensuring the safety of electrical and electronic components.
The product design enhances the overall quality of the cable connector, ensuring long-term stability of the electrical connection. The sealing ring won’t be lost or forgotten by the installer, as it fits perfectly onto the product, thus preventing incorrect installation of the connector. This facilitates quick and easy wiring for operators, and allows for re-inspection of the connection at any time.
Products have passed authoritative TUV/CE/cUL/SAA/CQC certifications and comply with REACH and RoHS standards.
