EKMB/EKMC Series Wide Area Detection PIR Sensors

Panasonic’s EKMB and EKMC series passive infrared or pyroelectric (PIR) motion sensors are designed to provide wide area detection spanning over 10.8 M. Their wide area detection allows a singular PIR motion sensor to cover an entire room. Their high signal-to-noise ratio ensures the prevention of false triggers. The EKMB and EKMC series have an advanced pyroelectric sensor design that improves the accuracy of detection.

These wide area detection 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. In addition, Panasonic integrates an amplifier and comparator circuit on the same chip, densely packed inside the stem block. The wide area detection 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.
