Mounting Instructions

Flush mountable tubular switches / CSA Div. 2

efector100®

Flush mountable switches can be mounted so that the active face is flush with a metal surface. Any metal in front of the switch should be kept at a distance of three times the nominal sensing range.

s = nominal sensing range b = maximum thread length M8 - 8 mm, M12 - 8 mm M18 - 8 mm, M30 - 16 mm

Two flat nuts are provided to hold the installed switch in place.

When mounting tubular switches opposite each other, the spacing distance shown here should be maintained.

Sr = nominal sensing range

When mounting tubular switches next to each other, the spacing distance shown here should be maintained.

D = switch diameter

CSA for Hazardous Locations

When wired in accordance with CEC and this mounting instructions.

Class I, Div. 2, Groups A, B, C and D

AVERTISSEMENT

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 according to the technical data sheet, if specified.
