PaPIRs -How to Choose Lens type-
Two times better sensitivity
Easy design-inThe integrated amplifier / comparator circuit inside a TO-5 metal can (digital type) prevents interferences caused by electromagnetic fields, such as those generated by cell phones and wireless devices. A special differential circuit design is introduced for the EKMB 6μA type for applications where a high noise resistance is required (up to GHz range).
Small and fancy lens designThanks to the special design of the small pyroelectric elements, it is possible to use a smaller lens size while keeping the same detection area and distance compared to conventional sensors.
Four times better signal-to-noise ratioImproved signal-to-noise ratio thanks to a special I/V circuit which is used for converting a current signal from the pyroelectric element to voltage. Panasonic PIR motion sensors perform by the feedback capacitor and the operational amplifier, different from the conventional FET-type, thereby decreasing the probability of false alarms due to temperature fluctuation.
Lead-free pyroelectric elementA ferroelectric Lithiumtantalate (LiTaO3) single lead-free crystal is used as the pyroelectric element for Panasonic PIR motion sensors. Conventional PIR motion sensors normally use a ceramic base material (e.g. PZT) for the pyroelectric element, which contains lead in many cases.
Low current consumption EKMB (WL)Reduction of current consumption (1, 2 or 6μA) thanks to the special circuit design technology allows battery life to be extended for battery-driven products.
It has various usages,including IoT-related devices and systems such as occupancy detection, monitoring, home appliance control, and intrusion detection, as well as high-bay lighting and street light control.
Home appliances: wide range of lens lineup, and slight motion performance
IoT: radiation noise resistance and low current consumption. (adjacent to wireless module, battery driven)
Lighting: S/N ratio and Slight motion performance. (Reduction of malfunctions and non-operations)
