LIGHT SENSOR SYSTEMS PART NUMBER INFORMATION

Milnor uses photoelectric sensors in a variety of our automated processes.
These optical controls work by detecting a visible or invisible beam of light, and responding to a change in the received light intensity.  
As a general rule, we use 4 types of light sensing systems.

• Reflector or Retroreflective systems

• Emitter - Receiver Pairings (for parts info on CBW load chute emitter/receivers with casings and internal parts click HERE

• Light Curtains

• Fixed Background (Background suppression)

REFLECTOR SYSTEMS

• Emitter and receiver in a single housing. 

• Light sent back to receiver with a reflector.  

• Output changes state when light beam obstructed.
  
  
  
  24-240V AC N/O output - part number 09RPE004

Either of the light sensors above can be and are paired with either reflector below. 
IP69K rating defined as Ingress Protection of solid objects and/or moisture.

EMITTER RECEIVER

• Thru beam light sensor w/ 1 emitting module and 1 receiving module. Receiver output changes state when light beam obstructed
  
  This is normally used in a wet environment like a centrifugal extractor cylinder opening to detect loose goods outside the cylinder.

Part Numbers 09RPE010E and 09RPE010R are very similar.  The receiver has an extra lead wire for output signal to control box.  

Light Curtains

• Used for a safety barrier primarily around Milnor Presses. 

• Contains 40 thru light beams. 

• Can have reflectors directing beams from emitter to receiver 

• Two attachments to this knowledge article contain important additional information for Light Curtains

Fixed Background

• Background suppression measures the angle of incidence (rather than the amount) of light reflected back to a receiver.

• Emitter and receiver in same housing

• Output changes state when object passes at predetermined distance
