The Major Tech PIR33 is a ceiling-mounted 360° PIR sensor designed for automated indoor lighting and device control. Detecting motion and body heat within a 6-metre range, it’s ideal for spaces like hallways, lobbies, offices, and bathrooms, helping reduce energy usage by activating lights only when needed.

The adjustable lux sensitivity (3–2000 Lux) and timed shut-off (10 sec to 15 min) allow you to customise performance to suit your space and schedule. Supporting up to 600W LED or 1200W incandescent, the PIR33 is easy to install with a 64mm cut-out size, and operates with ultra-low standby power.
