Pyroelectric Infrared Radial Sensor
TYPE: BS412
NANYANG SENBA OPTICAL AND ELECTRONIC CO.,LTD.

Digital Smart Pyroelectric Detector BS412

BS412 is a newest smart digital motion detector with a small window size. It offers a complete motion detector solution, with all electronic circuitry built into the detector housing. Only a power supply and power-switching components need to be added to make the entire motion switch.
BS412 includes the time setting only.

Features and Benefits

  • Digital signal processing(DSP)
  • Power adjustable, save more energy
  • Two-way differential high impedance sensor input and temperature compensation
  • Built-in filter, screen the interference by other frequency
  • Excellent power supply rejection, Insensitive to RF interference
  • Schmidt REL output

Application

  • Intelligent appliance
  • Alarms
  • Motion detector
  • Sensor lamp, Sensor switch
  • Security system
  • Automatic control etc.
