Safe explosion protection through ATEX-compliant housing

TR-Electronic has been a leading partner and accredited manufacturer of rotary encoders in the field of explosion protection for more than a decade. With ATEX-compliant housings for absolute rotary encodersabsolute rotary encoders with wire-actuated encoder and SIL3-/PLe-certified rotary encoders, you will be on the safe side even in potentially explosive atmospheres.

Our ATEX devices fulfil all necessary directives.

ATEX-compliant housing A_V 70

With housing series A_V 70, you can also utilize the interface diversity of series 58 in potentially explosive atmospheres in Zone 1 (gases) and Zone 21 (dusts). Solutions for direct interfaces (SSI, Analog) and field buses (PROFIBUS) are equally possible.
For aggressive or hygienically sensitive environments the complete housing is manufactured from stainless steel - optimal protection in flour mills and flour processing, for example. In the standard housing the AEV 70 can be used in excavating and conveying systems in brown coal opencast mining, as well as in the conveying systems of complete painting lines. It is also ideally suited for applications in plastic mills or the woodworking industry.

ATEX and SIL3/PLe certification in one

A special feature is the ADV 88 M – certified to SIL3 / PLe for functional safety and type-approved for Explosion Protection Zones 1 and 21. The ADV 75 combines explosion protection and functional safety particularly effectively and covers the area of Zones 2 / 22. Despite its very compact design, it is comprehensively fitted, e.g. PROFIBUS with Profisafe, 13 bit resolution and 32,768 revolution plus a lot more. For the first time you can achieve functional safety and explosion protection in one completely certified and approved device.
