Panasonic EKMB & EKMC Series "Wide Area Detection" Type Passive Infrared Or Pyroelectric (PIR) Motion Sensors
With new wide-angle lens detect objects over 10.8m span
Panasonic Industry has added to its EKMB and EKMC series of Passive Pyroelectric Infrared (PaPIR) motion sensors, introducing devices which offer a wide field-of-view for the detection of people and objects over an extended span of 10.8m.
The ‘Wide Area Detection’ PaPIR products feature a new wide-angle lens design which enables a single sensor to cover an entire room, performing functions such as intruder detection or presence detection. The lens divides the field-of-view into 208 detection zones, enabling the sensor to precisely locate detected objects.
The 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. The EKMC7608 parts are classed as ‘low sensitivity’ types, and the EKMC4608 as ‘high sensitivity’ types. The EKMB products, which feature low stand-by currents, are intended for use in battery-operated devices.
