B5B-PIR90 – Eunica PIR with frame in anthracite

Why Choose the Carlo Gavazzi B5B-PIR90 Eunica PIR Sensor?

The Carlo Gavazzi B5B-PIR90 is a Eunica passive infrared (PIR) movement sensor designed for Carlo Gavazzi smart-house building automation systems. Featuring a compact 55 × 55 mm format and anthracite frame, it provides discreet automatic presence and movement detection for intelligent lighting and building-control applications.

The sensor uses passive infrared technology to detect changes in thermal radiation as people or other heat-emitting objects move through its field of view. The Eunica PIR platform provides a 90° detection angle and is intended for wall-mounted indoor applications where automatic lighting control and occupancy-related functions are required.

Designed as an integrated smart-house sensor rather than a stand-alone mains switching device, the B5B-PIR90 communicates movement information to the building automation system, where it can be used to trigger programmed functions. This makes it suitable for residential, commercial and hospitality environments where automatic lighting can improve convenience and energy efficiency.

Reliable PIR Detection for Automated Lighting

The Carlo Gavazzi B5B-PIR90 responds to variations in infrared thermal radiation within its field of view. Its segmented PIR lens divides the monitored area into active and passive zones, enabling movement to be detected as a person passes between those zones. This provides a practical method of occupancy-related control without requiring physical interaction with a wall switch.

Within compatible Carlo Gavazzi configuration software, the B5B-PIR90 is represented using the B5X-PIR90-U motion-detector profile. The sensor sensitivity can be configured to suit the installation, while the integrated LED can be assigned as a guide light or used to provide feedback when presence or movement is detected.

Typical Applications

• Automatic residential lighting control.
• Carlo Gavazzi smart-house installations.
• Commercial offices and meeting rooms.
• Corridors, entrance areas and circulation spaces.
• Hotels and hospitality environments.
• Occupancy-responsive building automation.
• Automatic lighting for utility and service areas.
• Maintenance and expansion of existing compatible smart-house systems.
