1 / 8 page MP Motion Sensor (AMN2, 3, 4) Passive infrared human detection sensor with built-in amp. MP MOTION SENSOR ‘’ FEATURES 1. pyroelectric sensor modules contain the necessary functions in a small package (TO-5). These miniature, high-performance infrared human detection sensors take the trouble out of circuit design and mounting. 2. Ideal for small-movement detection thanks to quad-type pyroelectric element. The quad-type pyroelectric element contained in has four receptors. Since the detection zone within the detection range is so precise, even small movements can be detected. 3. Lenses can be miniaturized because the pyroelectric element is small A short focal length is all that’s required even when detecting at the same distance, because the size of the pyroelectric element is so small. This means that high precision is maintained even though the lens is small and the sensor itself has been miniaturized. 4. Small temperature differences also detected. detects the temperature difference between the detection target and its surroundings, and the lowest required temperature difference to the background is 4 °C 7.2 °F. This means that temperature differences can be accurately detected not only in winter, when the temperature differences are large, but also in summer, when temperature differences are slight. Standard type Slight motion detection type Spot type 10 m detection type Lens Lens Sensor module IC PIR element Chip parts PC board Shielded plate Capacitor Lens Quad-type pyroelectric element Focal length (distance between element and lens) Representation of detection Detection zone Small movement Surface temperature: 34 °C 93.2°F Winter Floor temperature: 22 °C 71.6°F Summer Floor temperature: 30 °C 86.0°F Large temperature difference Temperature difference: 12 °C 53.6°F Small temperature differences mean difficult detection. Temperature difference: 4 °C 7.2°F 5. Excellent noise resistance (radiation noise, power supply noise) The entire circuitry is enclosed in a metal package, which means it has extremely high electromagnetic shielding capabilities. With proven resistance against power supply noise, it is also resistant against power supply superimposed noise. GND Vd Radiation noise Power supply superimposed noise OUT ASCTB240E 201201-T Panasonic Corporation Automation Controls Business Unit industrial.panasonic.com/ac/e RoHS compliant |
