Key Features, Specifications & Benefits

Applications

• Label Detection on Packaging Lines
  In bottling and packaging lines, the sensor ensures labels are correctly applied by detecting their presence, even on transparent or glossy surfaces. Its visible red LED allows precise alignment, and background suppression eliminates false readings caused by reflective materials.

• Part Presence in Automotive Assembly
  Used in car assembly stations to verify small parts like clips or pins are properly installed. Its fast response time and high switching frequency allow it to detect fast-moving, low-reflectivity components without slowing down production.

• Defect Rejection on Conveyors
  Mounted above conveyors, the sensor identifies missing or misaligned items. Its rugged IP67 housing resists dust and splashing liquids, making it ideal for factory floors. The adjustable detection range helps fine-tune the sensor for different object sizes.

• Tablet Packaging Verification
  In pharmaceutical lines, the sensor confirms whether tablets are present in blister packs. Its fine detection beam accurately distinguishes between filled and empty compartments, ensuring packaging integrity without physical contact.

• Warehouse Storage Monitoring
  Deployed in racking systems to detect missing or misplaced bins. The compact housing fits into tight spaces, and the LED indicator offers immediate feedback for maintenance teams during stock checks or replenishment operations.

• Obstacle Detection in Automatic Doors
  Installed near door frames to detect obstructions such as people or objects. The sensor’s fast reaction time and background suppression make it reliable for detecting dark clothing or transparent barriers, enhancing safety in public access points.

• Component Check in Robotic Arms
  Mounted on robotic grippers to confirm a part has been successfully picked up. Its compact form and tight light spot allow integration in small end-effector spaces, while the quick response ensures timely feedback for the robot’s motion control.

• Splash Zone Monitoring in CNC Machines
  Placed inside CNC machines to monitor critical zones affected by coolant or debris. Its sealed construction prevents fluid ingress, while adjustable sensitivity helps detect even minor disturbances without being affected by mist or residue.
