When working in and around explosive atmospheres it is important to have a reliable partner to ensure the safety of both personnel and equipment.
With QUINTEX you are on your way to having a safe and reliable partner.
Where Line bushings are concerned QUINTEX can expand on your existing range and offer more possibilities for your security. Not only can we improve on the diverse range of wires, we can also expand on the various application fields.
This flexibility allows not only use in areas of explosion hazards (Ex d) but also in areas of increased safety (Ex e). These line bushings are available for use with stainless steel, GRP (Glassfibre Reinforced Polyester) or aluminum enclosures and housings.
QUINTEX have extended their certification:
II 2G Ex db eb IIC T4/T5/T6 Gb
II 2D Ex tb IIIC T135°C/T100°C/T85°C Db

In accordance with EN 60079-7:2007 the security of enclosures for increased safety areas (Ex e) must have a minimum safety class of IP54. This is also described in DIN EN 60079-14. (Fig. 1)
QUINTEX line bushings of Ex e type can be used with either an O-Ring or a flat gasket guaranteeing a minimum protection of IP66.
This also allows direct use in different applications:(Fig. 2)
