W 170 Photoelectric switches

W 170: Miniature photo-

electric switches – robust,

functional, complete

Thanks to the system’s large

scanning ranges, stainless-steel

housings, red transmission light

and the deliberate omission of op-

erating elements, this series of

photoelectric switches offers major

benefits for the user, such as sim-

ple handling and high functionality.

The L.ON/D.ON control cable

reduces the number of variants

by half.

The W 170 switches have, there-

fore, proven particularly successful

in the following sectors:

■ conveyor systems,

■ packaging industry,

■

assembly and handling systems,

and

■ construction of special-purpose

machines.

The scanning ranges:

■ WS/WE 170 through-beam

photoelectric switch: 7 m,

slotted masks and polarising

filter attachments as accesso-

ries. The polarising attachments

reduce mutual interference.

WS/WE 170 switches also

allow configuration of simple

light grids.

■ WL 170 photoelectric reflex

switch: 3.5 m (PL 80 A), with

polarising filter. Also available

as a version with reduced

switching hysteresis: especially

suitable for detecting trans-

parent objects such as glass

or film.

■ WT 170 photoelectric proximity

switch: energetic: scanning

distance 400 mm (90 % remis-

sion), for standard scanning

tasks; with focused optics:

scanning distance

10...90 mm, background

blanking, small light spot, high

sensitivity.

The mounting bracket and P 250

reflector (with WL 170) are

included. Enclosure rating IP 67,

= 10...30 V DC, PNP or NPN

switching output, M8 plug or

cable are all standard features of

the series.
