Mounting Instructions
Nonflush mountable tubular switches / CSA Div. 2
Nonflush mountable switches must have a metal-free zo-
ne surrounding the active face as shown here. And there
should be no metal behind the sensing face for a distance
equal to two times the nominal sensing range.
s = nominal sensing range
b = maximum thread length

ELECTRICAL
DO NOT operate an incandescent light bulb as a load.
The current inrush when the bulb is cold can cause a
current overload.
DO NOT operate a proximity sensor directly from a
voltage supply without a load. This is a short circuit and
can cause damage. Note: insert a miniature fuse accor-
ding to the technical data sheet, if specified.
Concerning Safety... ifm efector makes every effort to build a de-
pendable product, but every product will eventually fail. Therefore,
your equipment must be designed to prevent property damage
and personal injury if our products fail. ifm efector proximity
switches are not designed to be used as stand-alone devices to
protect or guard human life or limb.
WARNING
Explosion Hazard – substitution of components may impair suitability
of Class 1, Div. 2. Do not disconnect while circuit is live unless area is
known to be non-hazardous.
AVERTISSEMENT
Risque d'explosion - La Substitution de composants peut rendre ce
matérielle inacceptable pour les emplacements de classe I division 2.
Ne pas débrancher tant que le circuit est sous tensions, à moins qu'il
ne s'agisse d'un emplacement non dangereux.
CAUTION
Use only ifm efector conduit adapters (U30029, U30030, U30031) or
other CSA ceritifed conduit adapters.
ATTENTION
Utiliser uniquement les adaptateurs tube d'ifm efector (U30029,
U30030, U30031) ou d'autres adaptateurs tube certifiés par CSA.
