The ABB KNX Corridor Presence Detector (series 6131/50-xxx-500) provides rectangular corridor detection for aisles and circulation routes. Two channels with constant light switching keep lighting on only when people are present and daylight is insufficient.

Available in white, aluminium, and black finishes.

Key Features

• Rectangular pattern: Optimised for long, narrow corridors (align the device correctly).
• 2 channels: Occupancy- and brightness-linked lighting control.
• Sector groups: Sensor groups 1/2 and 3/4 can be disabled via parameters.
• Approach vs crosswise: Detection differs for central approach versus crosswise movement.
• Integrated KNX bus coupler: Direct TP connection.
• Three finishes: White (6131/50-24-500), Aluminium (6131/50-183-500), Black (6131/50-885-500).

Detection Range

• Corridor coverage: Rectangular footprint; mounting typically 2.5 … 4 m (see ABB datasheet).
