Reliable, safe relays for use in hazardous areas
R. STAHL's relays are versatile components for Ex e enclosures in Zones 1 and 2 that you can really rely on. They can be used for various applications, e.g. as impulse relays or time relays. They are all easy to install, robust, and corrosion-resistant.

R. STAHL's relays are installed in enclosures with Ex e type of protection and can be used for many different applications. They can be used as relays, impulse relays, relay modules or time relays. All relays have a corrosion-resistant enclosure and easily accessible connection terminals to make installation easier and allow for safe connection. They can be reliably secured in the enclosure with screws such that they do not vibrate.
