Details: SR.T*


The SR series is a flexible range of terminal boxes that are fully customizable. Enclosures can meet the needs of user specifications by being supplied with or without accessories such as cover hinges, mounting brackets or gland plates.

Enclosures are manufactured from brushed AISI 316L stainless steel and all fixings are manufactured from A4 grade stainless steel as standard to provide excellent tarnish and corrosion resistance.

Your solution can be mounted in portrait or landscape orientation in temperatures ranging from -60 ºC up to +90 ºC. For terminal and entry device configuration options please see overleaf. Further configurations can be confirmed by your local Pepperl+Fuchs office.
