Fotocélulas BFt THEA A15 O.PF UNI P111714 — par de fotocélulas de seguridad para motores no BFt

BFt THEA A15 O.PF UNI is a pair of safety photocells engineered for use with non-BFt gate and door drives. The set detects interruption of an infrared beam to provide perimeter protection and obstacle sensing, helping to reduce the risk of accidental gate or door closure. The compact housings and straightforward mounting make the photocells suitable for retrofit or new installations where basic presence detection and improved operational safety are required.

Advantages

The photocell pair offers reliable infrared beam detection with quick response to beam interruption, enabling consistent obstacle sensing for sliding gates, swing gates and sectional doors. Its compact dimensions and neutral styling allow easy integration into existing installations without major modifications. The devices are designed for outdoor use and deliver steady performance in typical residential and light-commercial environments, supporting safer gate and door operation.

Suitable for

• Retrofit safety upgrade of non-BFt automated gates and doors
• Perimeter protection for driveways, entrances and pedestrian access points
• Obstacle detection on sliding and swing gates, plus sectional garage doors
• Basic presence sensing for areas where a compact infrared detector pair is needed

Key specifications

• Detection method: infrared beam interruption
• Configuration: matched transmitter and receiver pair
• Mounting: surface or bracket mounting suitable for retrofit installation
• Environment: designed for outdoor use in residential and light-commercial settings
• Compact form factor for integration into existing gate and door systems

How to use

Install the transmitter and receiver units facing each other across the protected opening at an appropriate height for the expected obstacle detection profile. Align the optical axes and secure the housings to stable supports or brackets; then connect the wiring to the drive control following the drive manufacturer’s input wiring requirements. Verify alignment by checking indicator LEDs or alignment aids (if present) and test the system by interrupting the beam to ensure the drive responds according to safety logic. Perform routine inspections and realignment as needed to maintain reliable detection.

Recommendations

Position the photocells so the beam crosses the most likely path of people or vehicles to ensure correct obstacle detection. Keep lenses clean and free of obstructions, and avoid mounting in locations with direct strong sunlight on the sensor axis which can affect infrared detection. When integrating with a non-BFt drive, confirm compatibility with the drive’s safety input and follow applicable local safety standards during installation.
