Optex DX40 Dual Tech Sensor


The DX series integrated PIR and microwave technology provides stable and reliable detection in hostile environments. The Quad Zone Logic and Microwave Area Shaping incorporated in the DX series offers unparalleled sensing performance.

Key Features

  • Quad Zone Logic
  • Microwave Area Shaping
  • Spherical Lens Design

Quad Zone Logic

Quad Zone Logic provides multi-segmented detection zones throughout the detection area. An alarm signal is created by the cumulated total IR energy of each zone. It is designed to provide 4 to 8 zones for a human-sized object to create sharp and maximum signals for stable detection. Spot temperature changes, i.e. by rodents or curtains etc., may affect only one or two zones at the same time creating a smaller detection signal. These signals are further analysed by the “ECO” Chip and signal processing circuit for accurate detection and filtering out of false alarms.

Microwave Area Shaping

Prevents the unwanted detection of movement outside the coverage area.

Spherical Lens

Obtains an accurate focal length for each detection zone and maximises the performance of Quad Zone Logic.
