Function: FXLS*.T

The FXLS series is a range of terminal boxes that can be equipped with various types and quantities of terminals and cable glands.

The enclosures are manufactured from electropolished AISI 316L stainless steel as standard to provide excellent tarnish and corrosion resistance. This surface finish is ideally suited to meet hygienic requirements valid in pharmaceutical and food processing plants.

All FXLS enclosures feature a return flange sealing method which prevents accumulated dirt, dust and moisture from entering the enclosure when the hinged lid is opened.

Durable materials allows the terminal box to be used in ambient temperatures between -50 °C and +120 °C.

For terminal and cable gland configuration options please see overleaf. Further configurations can be confirmed by your local Pepperl+Fuchs office.
