ET 18 20 NPA S-1

The ET1820 is a family of gen- sensing performance. The sen-

eral purpose through-beam sors are easy to adjust with a

sensors in an industrial stan- 270° single turn potentiometer.

dard M18 nickel-plated brass The output is a 4-wire comple-

housing for heavy duty appli- mentary (NO and NC) circuit

cations. They are useful for with NPN (current sinking) or

simple applications where a PNP (current sourcing) open

basic sensor provide adequate collector transistor output.

Installation Hints

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
