ATEX Keyboard

ATEX Keyboard

(OP)
Hello,

I am trying to source an ATEX CAT 3D keyboard for use within a zone 22 dust environment.  The keyboard can be a simple querty style.  I have found CAT 2G & 3G keyboards from suppliers such Extronics, Bartec, Stahl etc but none seem to have got their act together and obtained the dust approvals.

I would appreciate any pointers.

Regards

Steve.

RE: ATEX Keyboard

If its ATEX category 3D (zone 22) it is possible that you can write the conformance document.  The device must be safe in normal operation for category 3 & with reference to the standards EN502581-1-1:1998 & EN50281-1-2:1998 you may be able to find a standard IP65 sealed keyboard from manufacturers like CKS http://www.cksholdings.com or read-consine http://www.readcosine.co.uk/ who also meet the impact requirement, all you then need to do is justify its "normal" use in zone 22 & document it as you would a technical construction file.
