Photocell sensor THI FAAC XP20D with adjustable receiver alignment (model 6525)

Photocell sensor THI FAAC XP20D with adjustable receiver alignment is an infrared beam interruption detector designed for automatic gates, barriers and door systems. The system consists of separate transmitter and receiver units that establish a reliable infrared beam to detect object presence or passage. It is suitable for both outdoor and indoor installation and offers adjustable optical alignment to fine-tune the sensing axis for accurate detection.

Advantages

The THI FAAC XP20D sensor provides stable detection through a focused infrared beam and adjustable receiver alignment that simplifies commissioning and reduces false triggers. Its separate transmitter and receiver design allows flexible mounting positions and clear line-of-sight configuration. The unit is engineered for compatibility with common gate and door control systems and supports reliable safety cut-off and access control functions.

Suitable for

• Automatic swing and sliding gates
• Vehicle barriers and parking access controls
• Automatic doors and industrial door systems
• Perimeter safety and pedestrian detection zones

Key specifications

• Infrared beam type for presence and interruption detection
• Separate transmitter and receiver elements for flexible installation
• Adjustable optical alignment on the receiver for fine-tuning
• Designed for indoor and outdoor use with appropriate mounting
• Compatible with standard gate and door automation control inputs

How to use

Mount the transmitter and receiver facing each other across the intended detection zone, ensuring a clear line of sight between units. Use the adjustable alignment mechanism on the receiver to center the infrared beam and confirm stable reception. Connect the sensor outputs to the gate or door control unit according to the control system wiring diagram and perform functional tests to verify beam interruption triggers the expected safety or control response. Periodically inspect the optical surfaces and alignment, and clean as needed to maintain performance.

Usage recommendations

Place the transmitter and receiver at appropriate heights and protected from direct contamination or strong light sources such as direct sunlight or headlights. For outdoor installations, use weatherproof mounting and ensure cabling is rated for external use. Test operation after extreme weather or mechanical impacts and recalibrate alignment if detection becomes inconsistent.
