Details: GR.T*


The GR.* series can be equipped with various types and quantities of terminals, entry devices and accessories. Pepperl+Fuchs solution engineering teams provide any custom configurations including combinations of terminals and controls.

This standardized enclosure series for all Pepperl+Fuchs products consists of carbon-loaded, glass-fiber reinforced polyester with stainless steel cover screws. The enclosure series provides an anti-static, UV stabilized and corrosion resistant solution. Many features provide for easy installation and handling.

It is certified for operation in low temperatures of down to -60 °C and thus can be applied in many applications as a replacement for stainless steel.
