Photocell sensor FAAC XP20WD wireless eye adjustment model 11809

FAAC XP20WD wireless photocell with eye adjustment is a photoelectric sensor designed to detect obstacles and control automated gates and barriers. The model provides a wireless connection between transmitter and receiver units, enabling beam alignment and sensor configuration without running signal cables. Intended for residential and light commercial gate automation, this photocell increases operational safety by stopping or reversing closing movements when an obstruction is detected and simplifies installation and maintenance through wireless pairing and adjustable aiming.

Advantages

The wireless design removes the need for a dedicated communication cable between transmitter and receiver, reducing wiring time and allowing placement flexibility. Eye adjustment enables precise alignment of the infrared beam to accommodate variable installation distances and mounting positions. The sensor operates as an active safety device for automated gates and barriers, providing reliable obstacle detection and integration with common automation control systems. Low-profile housings and weather-resistant construction support outdoor installation and continuous operation in typical gate environments.

Suitable for (tasks / use cases)

• Residential driveway gates with automatic opening and closing
• Light commercial or small business entrance barriers
• Replacement of wired photocells where cable routing is impractical
• Safety retrofit projects to prevent gate collisions and entrapment

Key specifications

• Wireless infrared photoelectric sensing for transmitter–receiver operation
• Adjustable optical alignment (eye adjustment) for precise beam targeting
• Range suitable for typical gate spans used in residential and light commercial sites
• Weather-resistant outdoor housings designed for fixed mounting on posts or posts brackets
• Compatibility with standard gate and barrier control inputs for safety edge or photocell circuits

How to use

Mount the transmitter and receiver facing each other on opposing posts or fixed supports so the infrared beam has a clear line of sight across the gate opening. Use the eye adjustment mechanism to fine-tune beam alignment until the receiver reliably detects the transmitter signal at the intended operating distance. Pair the wireless units according to the manufacturer's instructions so the receiver communicates with the gate control board. Connect the photocell outputs to the automation control’s safety or stop input following the control panel wiring diagram and electrical safety rules. Test operation by passing an object through the beam and confirming the gate stops or reverses as required.

Usage recommendations

Place the units where vegetation, dirt, or direct sunlight are least likely to interfere with the infrared beam. Regularly inspect and clean the lenses, check alignment after strong impacts or high winds, and verify wireless communication and battery or power status during scheduled maintenance to ensure continued reliable safety operation.
