Panasonic's new "Low Profile" Type PIR Motion Sensors offer a 10.9 mm profile alternative! This new line extension to the existing EKMB and EKMC Series line up features a lower profile alternative to the standard lens design (10.9mm versus 14.4mm height). Panasonic's new "Low Profile" type PIR Sensors consists 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. In addition to this, Panasonic also integrates an amplifier and comparator circuit on the same chip all densely packed inside the stem block. These new PIR Motion Sensors feature a one-chip ASIC design that is superior to discreet solutions by saving space, adding electromagnetic shielding to all circuitry and cutting down on the number of components required.
