Ordering Key

UC 80 CND 40 ER

A diffuse ultrasonic sensor
with a sensing of 400-4000
mm with an analog RS485
communication output. Both
the housing and the sensor
transducer are designed for
tough environment. A high
carrier frequency secures a

precise measuring and high
noise immunity. Due to use of
microprocessor control the
digital filtering make the sen­sor very immune against most
electromagnetic interferences
and enables synchronisation
in an easy way.

Installation Hints

Relief of cable strain Protection of the sensing face Switch mounted on mobile carrierTo 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

Incorrect

Correct

The cable should not be pulled

A proximity switch should not serve as
mechanical stop

Any repetitive flexing of the
cable should be avoided
