Frequently Asked Questions about ATEX Encoders

What are ATEX encoders?

ATEX encoders confirm to the requirements of the ATEX 214 equipment directive for potentially explosive atmospheres. A certification of compliance and mark issued by a certifying body authorizes the use of the encoder in a specific explosive environment with a specific level of risk.

What are Ex encoders?

The term Ex is a general term referring to encoders and sensors that qualify for use in a Hazardous or Explosive environment versus a Safe or General Purpose area. To support correct specification an equipment manufacturer will want to know what standard(s) and area classification needs to be met.

What are the different types of ATEX encoders?

ATEX encoders are classified by the area or Zone they are qualified to operate in, whether the hazard is gas or dust, the technique used for protection and the maximum safe operating temperature. A product marking will be issued by the certifying body for the specific area which can be seen on each product datasheet.

What are common protection methods used in ex encoder design?

Depending on the area classification and market preferences, manufacturers will commonly design product for ATEX compliance using Flameproof (similar to explosion proof), Intrinsically Safe, Increased Safety, Non Incendiary and Encapsulation techniques, as well as combinations of techniques. Choose the device that meets the Area Classification first, followed by other application preferences.
