Two supply voltage ranges with

interface to permit further
processing of sensor signals are
available:
low voltage 10 . . . 30 V DC with
PNP or NPN switching output,
with M 12 plug, 4-pin (rotatable
by 90°) or connecting cable. The

T

the number of variants by half.
The W 250 series of photoelectric
switches is characterised by large Universal voltage 12 . . . 240 V DC
scanning ranges, simple handling and 24 . . . 240 V AC, with
