IECEx Encoders
Certified position and speed feedback for hazardous areas.
Kübler IECEx encoders are internationally certified to meet the Australian standards for hazardous areas.
IECEx encoders are used where flammable liquids, gases or combustible dusts are likely to occur such as refineries, gas power plants, chemical plants, IECEx motors, oil platforms and grain silos.
Kübler offer a full range of Zone 1/21 encoders that are suitable for this environment and additionally provide a range of encoders that have been certified with M2 Mining approval.
It starts before the order
Three questions we ask alongside the part number, so the encoder you specify is certified for the area it goes into.
Where does it run?
Zone 1 or 21, or a mine pit needing M1 or M2. Offshore and seawater exposure, temperature class, and the shaft it mounts to.
What is it doing?
Speed or position. Incremental, absolute singleturn or multiturn, the bit depth required, and solid or hollow shaft.
What if it is wrong?
Ignition risk, an uncertified device in a classified zone, an audit finding, position lost, a plant shut down.
ATEX vs IECEx. What is the difference?
ATEX and IECEx are very similar, but there are some differences between each certification. The main difference is the geographical location where the certification is recognised and accepted.
ATEX is a requirement in Europe
IECEx is accepted across several countries internationally, including Australia and meets Australian standards
Part number guide
The part number tells you the feedback type and the shaft version. Zone 1/21 runs in the 70xx series, M2 Mining in the 71xx series.
IECEx certified encoders — Zone 1/21
IECEx certified encoders — M2 approved
M1 and M2. Which one does your pit need?
M1
Devices can be used if there is methane gas detected in the mine pit.
M2
Devices must be switched off if there is methane gas detected in the mine pit.
