The Major Tech PIR31 is a compact PIR motion sensor designed to automatically switch lights or devices on when movement and body heat are detected. Offering 360° detection when ceiling mounted (up to 6m range) and 120° detection from walls (up to 8m range), it provides flexible installation for different spaces. Its adjustable Lux sensitivity (3–2000 LUX) and time delay (10 seconds to 8 minutes) allow the sensor to respond appropriately to ambient lighting conditions.
Rated for 800W incandescent and 400W LED/CFL loads, the PIR31 is suitable for low to medium applications. The sensor head is IP65 rated for damp or outdoor use, while the controller unit is IP20 rated for indoor protection, making it ideal for both sheltered outdoor and indoor setups.
