Panasonic — EKMB, EKMC Series of PaPIR Motion Sensors

Panasonic has extended its EKMB and EKMC series of Passive Pyroelectric Infrared (PaPIR) motion sensors with a new low-profile product which has an inconspicuous flat and square 9.6mm x 9.6mm lens. These new PaPIR sensors have a 10.9mm profile which gives manufacturers an opportunity to create new, discreet designs which hide the normally obtrusive motion detector from view.

The new flat and square products join the existing EKMC family sensors, which draw an operating current of 170µA, and the EKMB family for battery-operated devices. EKMB sensors run on an operating current of 1µA, 2µA, or 6µA. Mounted on walls, ceilings, or corners, the flat and square PaPIR sensors offer a typical detection range of 5m.

All PaPIR products are available with a digital output and preset sensitivity, or with an analog amplifier output which allows for adjustment of the sensitivity. The sensors are composed of the lens, an optical filter to block non-infrared light, pyroelectric sensing elements, and an impedance converter which provides an electrical output signal.

In addition, Panasonic also integrates an amplifier and comparator circuit on the same sensor ASIC in the stem block, an architecture which saves space and allows for electromagnetic shielding of all circuitry while reducing component count. A high signal-to-noise ratio ensures that the sensors avoid false triggering events.

The EKMC and EKMB PIR sensors are available with a white, black or pearl white lens.
