供应红外传感器 LHI778/878

产品品牌：Perkinelmer

产品型号：LHI778/878/968

  产品名称：LHI778
 
  产品编号：红外传感器LHI778
  产品规格：双元热释电红外传感器 8.3*4.2mm 
  产品说明：
  The LHi 778 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 with FET in source follower connection. The LHi 778 is available as TO-5 housing with standard infrared filter. It provides for high responsivity with excellent common mode performance (match). RF improved options are available.

Best choice for human body detector. Highly sensitive to human body while remaining insensitive to ambient temperature change, vibration or optical noise. This is due to the dual configuration which electrically cancels such effects

说明 该传感器采用热释电材料极化随温度变化的特性探测红外辐射，采用双灵敏元互补方法抑制温度变化产生的干扰，提高了传感器的工作稳定性。
使用 1、上述特性指标是在源极电阻R2=47KΩ条件下测定的，用户使用传感器时，可根据自己的需要调整R2的大小。
2、注意灵敏元的位置及视场大小，以便得到最佳光学设计。
3、所有电压信号的测量都是采用峰一峰值定标。平衡度B中的EA和EB分别表示两个灵敏元的电压输出信号的峰一峰值。
4、使用传感时，管脚的弯曲或焊接部位应离开管脚基部4mm以上。
5、使用传感器前，应先参考说明书，尤其要防止接错管脚
