The integration of sensor and detector in one unit eliminates component drift caused by temperature changes and ageing.
Sharp has released two compact distance measurement sensors, designed for battery-powered applications, particularly automated sanitary equipment where a power supply is unavailable or unsuitable for safety reasons.
Both sensors (GP2Y0D805Z0F and GP2Y0D810Z0F) are equipped with the industry's first external Standby pin that cuts, when activated, power consumption down to 5uA.
Used on an average tap this feature enables an extended battery lifetime up to more than 5 years.
The pin allows the fixture to limit the number of hours the device remains "on".
Supported supply voltage are 2.7V to 6.2V, making them ideal for battery-powered applications.
The compact size of 13.6 x 7.95 x 7.0mm enables easy integration and optimised board space usage in size limited applications.
The sensors come in two popular sensing distances, 5cm and 10cm.
These new distance measuring sensors offer accuracy, longevity, and simple design-in, plus they cost less than previously used sensors.
The integration of sensor and detector in one unit eliminates component drift caused by temperature changes and ageing, and provides extremely high component reliability compared to a discrete solution.
Sharp's sensors rely on the principle of triangulation instead of reading the intensity of reflected light, so sensing is consistently accurate, regardless of sensed object colour.
The sensors feature special miniaturised packaging that combines both the emitter and detector in one simple device.
Mechanical engineering is simplified because the devices are pre-focused to 5cm and 10cm respectively.
Detection is not based upon the intensity of returned light, but rather geometry, resulting in robust performance that is independent of the sensed object's reflectivity.
The four degree average emission angle yields high sense accuracy since the tighter the emission beam angle, the more accurate the performance.
Electronic engineering becomes much simpler without estimating degradation of the emitter and detector over time, and the trigger distance won't drift with degradation, as with intensity-based sensing.
"Our two new distance measuring sensors let designers create automatic fixtures with both aesthetic appeal and simple operation", said Andreas Biss, Optoelectronics Product Manager for Sharp Microelectronics Europe.
"Sharp's Optoelectronics leadership and innovations give engineers the assurance of highly reliable sensors and greater design flexibility at a good price".
