Description

LHI778 Infrared Thermoelectric Sensor For Human - body Movement Detectors

Product Features:

  • It has a TO - 5 metal housing and different window sizes are available6. The LHI778 is designed to meet low - cost requirements and is equipped with a small - sized optical window.
  • It is a dual - element detector, which includes a dual - element pyro - electric ceramic element with a FET in source - follower connection.
  • It provides high responsivity, excellent common - mode performance (match), and has low noise in both steady - state and temperature - change conditions.
  • It has improved EMI protection and reduced white - light immunity (WLI).

Technical Parameters:

  • Minimum Responsivity (Rmin): 3.3
  • Typical Responsivity (Rtyp): 4.2
  • Maximum Match (Mmax): 10
  • Maximum Noise (Nmax): 50
  • Typical Noise (Ntyp): 20
  • Detectivity (D*): 20
  • Horizontal Field of View: 71°
  • Vertical Field of View: 71°
  • Source Voltage (Operating Voltage): 0.2 - 1.5V

Application Scope:

It is suitable for human - body movement detectors, passive infrared anti - theft alarms, automatic light switches, intrusion alarms,

high - end motion sensors, etc.

Packaging and Certification:

  • Packaging: Usually in tray packaging.
  • Certification: CE, RoHS.
