** The IP69K test according to DIN 40050-9 for high-pressure, high-temperature wash-down applications.

The sensor must not only be dust tight (IP6X), but also able to withstand high-pressure and steam cleaning.

The sensor is exposed to high pressure water from a spray nozzle that is fed with 80°C water at 8’000–

10’000 KPa (80–100bar) and a flow rate of 14–6L/min. The nozzle is held 100 –150 mm from the sensor at

angles of 0°, 30°, 60° and 90° for 30s each. The test device sits on a turntable that rotates with a speed of 5

times per minute. The sensor must not suffer any damaging effects from the high pressure water in appear-

ance and function.

Installation Hints

Capacitive sensors have a

unique ability to detect al-

most any material in liquid or

solid form. Capacitive sen-

sors are able to detect me-

tallic as well as non-metallic

objects. However, their tradi-

tional use is for non-metallic

materials such as:

• Chemical Industry

Cleansers, fertilizers, liq-

uid soaps, corrosives and

petrochemicals.

• Packaging Industry

Package inspection for lev-

el or contents, dry goods,

fruits and vegetables, dairy

products.

The nominal sensing distan-

ce for a capacitive sensor

is referred to a grounded

metal plate (ST37). For addi-

tional information regarding

dielectric ratings of materi-

als please refer to Technical

Information.

• Wood Industry

Saw dust, paper products,

door and window frames.

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.

• Ceramics & Glass

Industry

Raw materials, clay or

finished products, bottles.

• Plastics Industry

Resins, regrinds or mould-

ed products.

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

Not correct

Correct

The cable should not be pulled

Any repetitive flexing of the

cable should be avoided

A proximity switch should not serve as a

mechanical stop
