What this photocell does
Safety reaction
The photoelectric beam runs between TX and RX. When something breaks the beam, the drive stops or reverses, based on your control board logic.
- Protects people, cars, and property in the gate path.
- Supports sites that run auto close.
- Reduces service calls caused by impact events.
Where it fits
- Sliding gates for villas, compounds, warehouses.
- Swing gates for residential and business entrances.
- Garage doors where vehicles and pedestrians share the same lane.
