Your Say
SICK EX Series Photoelectric Switches for Explosive Areas
"Ex" series modules are designed for explosive areas in ignition protection Type "n" according to EN 50021. Hence, they conform to Categories 3G and 3D, based on the new 94/9/EC (ATEX) Directive, and can be used in the areas "Zone 2 (gas)" and "Zone 22 (non-conductive dust)".
In addition to limit values for temperature, performance or UV resistance, the Standard stipulates a mechanical strength which cannot be achieved with standard sensors.
The Category 3D/3G photoelectric switches from SICK are equipped with a metal housing. This housing meets the demanding requirements of the Standard and therefore offers a ready-to-fit solution in respect of the standard.
