Panasonic EKMB and EKMC Flat Square Lens Passive Infrared (PIR) Motion Sensors feature both a low profile and flat surface, ensuring a flush design look against the surface of a build. These PIR sensors consist of a lens to create various detection zones, an optical filter to block non-infrared light, pyroelectric sensing elements, and an impedance converter to get an electrical signal. The flat PIR sensors also integrate an amplifier and comparator circuit on the same chip, all densely packed inside the stem block. EKMB and EKMC Flat Square Lens PIR Motion Sensors utilize Panasonic’s one-chip ASIC design, which saves space, adds electromagnetic shielding to all circuitry, and reduces the number of components required. These PaPIRs are available in black, white, and pearl white. Ideal applications are HVAC, security, and lighting, including motion and occupancy detection.
