Dual Element Pir Motion Sensor LHI968
The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature. Dual compensated sensing elements are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved Our products can be used in many applications.
The LHi 8788 pyroelectric infrared-detector series are the standard dual element
design recommended for all variants of motion control. They include a dual element pyro-electric ceramic element with Fet in source follower connection.
LHi 878 detector is available in TO-5 housing with standard infrared filter. It provides high responsivity with excellent common mode performance (match) and low noise at steady state and temperature changes.
