Telemecanique certified sensors for explosive dust environments
The Telemecanique Sensors line of hazardous dust atmosphere sensors are compliant with the global international standard IECEx and the latest European ATEX directive. Choosing a Telemecanique sensor for hazardous dust machine applications ensures that the sensor has been tested and certified to perform in a manner compliant with prominent, established safety standards.
ATEX (defined by AT: atmosphere and EX: explosive), IECEx and NEC 506 all use the same protection concept called the Zone system. The Zone defines the probability of the hazardous material (dust) being present in sufficient quantities to produce explosive or ignitable mixtures.
- Zone 20 - An area where combustible dusts or ignitable fibers are suspended in the air continuously or for long periods of time.
- Zone 21 - An area where combustible dusts or ignitable fibers are likely to be suspended in the air under normal operating conditions.
- Zone 22 - An area where combustible dusts or ignitable fibers are, under normal operating conditions, not likely to be suspended in the air and do so for only a short period of time.
Telemecanique Sensors offers various ranges of Sensors that are ATEX and IECEx certified for use in all Zone 21 or Zone 22 applications. These hazardous area certified products include limit switches XC series, pressure control sensors XM series, inductive proximity sensors XS series, emergency stop cable pull switches and safety switches.
