The GBC 64.2300.50 is a ceiling-mount PIR sensor that activates a connected electrical load as soon as movement is detected within its operating zone. Mounted centrally on a ceiling, its 360° detection pattern eliminates blind spots that wall-mounted detectors can leave, making it particularly effective in square or circular rooms and open-plan spaces.

The sensor operates across an ambient brightness range from below 3 lux to 2000 lux, so it responds equally in full daylight and in darkness. The connected load timer is adjustable from 10 seconds to 8 minutes, and the light sensitivity threshold is independently adjustable to limit activation to specific ambient light conditions.

Key Features

• 360° horizontal detection angle for full-room coverage from a single ceiling position
• Detection distance: 6 m radius
• Adjustable light sensitivity: <3–2000 lux
• Adjustable activation timer: 10 seconds to 8 minutes
• Detection speed: 0.6–1.5 m/s
• Ceiling-mount assembly
• Maximum installation height: 3 m
• IP20 indoor protection rating
• White housing

Product Benefits

• The 360° detection cone from a single central mounting point covers an entire room without the partial coverage gaps associated with wall-mounted sensors
• An independently adjustable lux threshold lets the sensor be programmed to activate only at dusk or below any specific light level
• The 10-second minimum timer makes the sensor practical for high-traffic corridors and stairwells where continuous re-triggering is expected
• The 3 m maximum installation height suits most commercial and residential ceiling heights while maintaining the full 6 m detection radius at floor level
