Novel high resolution colour sensor technology promises to bring a new level of accuracy to automated colour selection/detection.
RoHS-compliant, non-contact device
Wide-gap optical sensor that includes an emitter-sensor pair consists of an LED and a phototransistor designed to operate efficiently over distances up to 30cm in industrial environments.
According to Dale Teeters, Automotive Business Unit Director for Optek Technology, Autopad is a cost-effective, versatile technology that can be used for a wide range of automotive and vehicle position sensing applications, including chassis sensors.
"For chassis sensors, Autopad provides a linear ratiometric output signal relative to rotary or linear displacement", said Teeters.
"This provides the necessary feedback for load leveling and active suspension systems".
The programme, one of the current wins for Optek's Autopad technology, is expected to generate more than $14 million in sales, Teeter explained.
Shipments are expected to begin in 2009 for the 2010 model year.
In addition to chassis height sensors, the Autopad technology is ideal for headlamp leveling, ride height and suspension control, power lift gate sensors, pedal and steering sensors, engine and emissions control, PRNDL (gearshift) shifters, transmission sensors, and vehicle user interfaces.
Autopad exhibits a linear sensing range of 20-220mm, with angle sensing at 360, 2x180, 3x120 and 4x90 degrees.
Accuracy is better than 1% and typical linearity is +/-1%.
Measurement speed for the device is less than 1ms, with a current consumption of less than 10mA.
Operating temperature range is -40 to +150C.
Autopad technology features analogue, ratiometric, PWM and digital outputs.
