To avoid interference from inductive voltage/
current peaks, separate the prox. switch
power cables from any other power cables,
e.g. motor, contactor or solenoid cables

mechanical stop
Mode of Operation
The sensor contains IR trans-
mitter, receiver and amplifier
with transistor output. The
light source is a Ga-As diode
emitting infrared light in short
pulses.
The conical tip of the sensor
forms an angle of 90ºC. This
angle acts as a prism, i.e. the
beam, emitted from the Ga-
As diode placed in one side of
the sensor head, is reflected
internally to the phototransis-
tor placed in the other side of
the sensor head, provided

Switch mounted on mobile carrier
Any repetitive flexing of the
cable should be avoided
that the tip of the sensor is si -
tuated in free air. If the sensor
tip is immersed in a liquid,
always having a refractive
index different from air, the
beam will not be refracted by
the prism and the photo tran-
sistor will not receive any sig-
nal.
The sensor types can operate
in oil, waste water, aqueous
solutions such as beer, wine,
alcohol etc. without any kind
of accessory.
