GP2D05
Distance Measuring Sensor of
1-bit Output
Features
1. Distance measuring type object sensor
Distance measuring range : Optional distance can be
(
set as threshold level by means of built-in VR
2. Impervious to color and reflectivity of reflective object
3. High precision distance measurement through output of
continuous measurement average value
4. Low dissipation current at OFF-state
(dissipation current at OFF-state : TYP. 3 µA)
■
Applications
1. Sanitary sensors (human body detection)
2. OA equipment (paper detection)
3. Game equipment
4. For consumer products (human body detection)
