EKMB/EKMC Series Ultra-Slight Motion PIR Sensors

Panasonic’s EKMB and EKMC series ultra-slight motion type passive infrared or pyroelectric (PIR) motion sensors offer improved sensitivity in slight motion applications. These PIR motion sensors are designed to provide ultra-slight motion detection, and their high signal-to-noise ratio ensures the prevention of false triggers. Their advanced pyroelectric sensor design improves the accuracy of detection.

Panasonic’s ultra-slight motion type 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. Panasonic also integrates an amplifier and comparator circuit on the same chip, densely packed inside the stem block. The ultra-slight motion type PIR sensors feature a one-chip ASIC design which is superior to discreet solutions by saving space, adding electromagnetic shielding to all circuitry, and cutting down on the number of components required.
