The Mighty Mule R4222 Photo Eyes gate safety sensor delivers reliable obstruction detection for your automatic gate opener by stopping gate movement whenever a beam is interrupted, keeping vehicles, pets, and people safe. Designed as a photoelectric safety device accessory, it integrates seamlessly with your gate system for non-contact protection and easy installation. 

  • Photoelectric safety device detects obstructions to prevent gate closure on vehicles, people, and pets. 
  • Non-contact safety sensor uses a beam of light to monitor the gate path without physical contact. 
  • Easy DIY installation mounts photo eyes on either side of your gate in minutes. 
  • Reliable operation halts gate movement at the first sign of an obstruction, giving you peace of mind. 
  • Simple wiring to each sensor (RB509-100 recommended) and your gate opener control board for full functionality. 
  • Designed as an accessory for automatic gate openers to enhance overall system safety. 

The photo eyes are required to be wired to each other (RB509-100 recommended) and one photo eye must be connected to the opener control board.
