Description
The compact ultrasonic sensors of the UPR-B series are
characterized by good price and short design. Nevertheless,
they have a wide range of max. 1m as well as a robust metal
housing. And they can be synchronized among themselves
and stopped with an external signal (suppression mode).
The sensor is available as a proximity switch with either PNP
or NPN output. Suitable applications include object as well as
level detection of all kinds of material.
The switching output can be programmed by the user
(NC/NO or window). Programming is done using a single
teach input. Optionally a teach-in box is available. For the
traditionalists exists a version as well with setting of switching
distance by potentiometer. This has a 2m long cable with free
end instead of the M12 connector.
Thanks to the new transducer sealing the UPR-B sensors are
very robust against many environmental influences. In
particular, they are oil resistant, unlike many other ultrasonic
sensors.
Blind range
The lower detection range between 0…100mm is called blind
range. It is typical for ultrasonic sensors. In the blind range
no measurement is possible.
Setting the switching points
The switching points are set by connecting the teach input
with either the power supply –U
B
(0V) or +U
B
(+24VDC).
The blinking LED shows during teaching if the sensor has
detected the object.
 LED blinks yellow: detected
 LED blinks red: not detected
Window operation NO
 Place the object on the near switching point
 Teach switching point with –U
B
 Place the object on the far switching point
 Teach switching point with +U

Window operation NC
 Place the object on the near switching point
 Teach switching point with +U

 Place the object on the far switching point
 Teach switching point with -U

Switching point NO
 Place the object on the switching point
 Teach switching point with +U
B
 Let the sensor look into the empty space (>1m)
 Teach with -U

Switching point NC
 Place the object on the switching point
 Teach switching point with –U

Caution:
The teach wire must not be connected during normal
operation. The sensor can e.g. be operated after teaching
with a 3 wire cable.
Electrical connections (view to the sensor)
Synchronization ("Y" option)
If several sensors are placed close together and scan the
same object or if a common background is present, the
sensors must be synchronized. For this, the Teach/Sync.
leads of all sensors (max. 6 sensors) are interconnected.
Important is the order:
1. teach each sensor individually (!)
2. turn off the power
3. interconnect all Teach/Sync. lines
4. power on again only when everything is wired!
