Installation Hints

Delivery Contents

Capacitive sensors have the

unique ability to detect al-

most all materials, either in li-

quid or solid form. Capacitive

sensors can detect metallic

as well as non-metallic ob-

jects, however, their traditi-

onal use is for non-metallic

materials such as:

• Wood Industry

Saw dust, paper products,

door and window frames.

• Capacitive switch: CB18CL...

• Screw driver

• Packaging: Cardboard box

• Installation & Adjustment Guide

Materials are detected due to

their dielectric constant. The

bigger the size of an object,

the higher the density of ma-

terial, the better or easier it is

to detect the object. Nominal

sensing distance for a capaci-

tive sensor is referenced to a

grounded metal plate (ST37).

For additional information

regarding dielectric ratings

of materials please refer to

Technical Information.

• Plastic Industry

Resins, regrinds or moulded

products.

• Agriculture

Feed, solids or grain.

To avoid interference from inductive voltage/

current peaks, separate the prox. switch pow-

er cables from any other power cables, e.g.

motor, contactor or solenoid cables

Relief of cable strain

Protection of the sensing face

Switch mounted on mobile carrier

Incorrect

Correct

The cable should not be pulled

Any repetitive flexing of the

cable should be avoided

A proximity switch should not serve as

mechanical stop
