Degree of protection

The degree of protection assured by the cable entries is IP66 according to IEC/EN 60529 standard. For cable entries with cylindrical thread the degree of protection IP66 is assured by using either a flat silicone MVQ gasket of a flat PTFE gasket or a SILICONE MVQ O-ring. For cable entries with conical thread the degree of protection IP66 is assured by applying to the threading of sealing LOCTITE 241.
Metric cable glands are made in accordance to EN 62444 Standard.
