XU photoelectric sensors
Technologies
• Detection of any objects without contact (no touch), opaque,
shiny, or transparent. Direct detection of objects (cases, pallet,
etc.), person, vehicles (trolley, wagon, etc.)
• Long range detection -> 60 m
• High operating rate
• Available with background suppression
+
• Not suitable for hash environments: dirty, dust
• Temperature range limitations
• Risk of interference between photocells themselves-

Overview — Photoelectric/photocell sensors
Photoelectric sensors have universal application. If there is any
doubt about the specific type of sensor that should be used,
a photoelectric sensor is a good choice. Photoelectric sensors
have a wide range of applications. For example:
• Monitoring position or presence of parts
• Detection of the height of objects on a conveyor
• Detection of product, pellet, powder levels
Brand name:
• OsiSenseTM
XU

10. Telemecanique Sensors – May 2016 10
Thru-beam
Thru-beam is used for long-distance detection.
The object cuts through the beam.

11. Telemecanique Sensors – May 2016 11
Diffuse
Diffuse uses the reflective properties of the target.

12. Telemecanique Sensors – May 2016 12
Diffuse with background suppression
Diffuse with BGS discriminates between the background and the
target. Therefore, the detection of targets is achieved at the same
range regardless of the color of the target object. The object returns
the beam and the background is learned and ignored.

13. Telemecanique Sensors – May 2016 13
Reflex
Reflex is used for opaque targets. The object cuts through the beam.

14. Telemecanique Sensors – May 2016 14
Polarized reflex
Polarized reflex is used to detect shiny objects. The object cuts through the beam.

15. Telemecanique Sensors – May 2016 15
Technical key points — Detection system
• Diffuse
• Short-distance detection 2 m
• Using target reflective properties
• Only one device to install
• Diffuse with background
suppression
• Same but with discrimination
between background and target
• Short distance detection 1.3 m
• Thru-beam
• Long-distance detection 40 m
• Accuracy of detection
• Two devices to install and connect
• Reflex (and polarized)
• Medium-distance detection 15 m
• Need a reflector
whose size < object size
• Reflex for opaque targets
• Polarized reflex for shiny targets

16. Telemecanique Sensors – May 2016 16
Technical key points — Electrical function
• Output function
• Normally open (NO)
– Corresponds to a sensor whose output
is activated to the closed state when
the object to be detected is present
• Normally closed (NC)
– Corresponds to a sensor whose output
is activated to the closed state when
an object to be detected is not present
• Complementary outputs (NO + NC)
– Corresponds to a sensor with a
normally closed output and a normally
open output

17. Telemecanique Sensors – May 2016 17
Technical key points — Output function
• For receiver
• 3-wire type DC
̶ NO or NC output, PNP, or NPN
• 5-wire type AC/DC relay
̶ NO and NC complementary outputs
• For transmitter
• 2-wire for power supply
• Specific output signals, analog type

18. Telemecanique Sensors – May 2016 18

How to choose a photoelectric sensor?
1. Choose a system according to environment, sensing distance,
and detection accuracy
• Balance between place to install, access to object on one or two sides,
sensing distance, and accuracy of detection.
2. Choose the electrical function
• According the automatism function to achieve
– NO, NC, NO+NC, analogue, etc.
• According to the "load" compatibility (contactor, PLC, etc.)
– DC 3 wires PNP, NPN, AC/DC 5 wires relay
3. Choose the electrical connection according to habits
(geographical use)
• Cable, connector, screw clamp terminals
