CARROLLTON, TX (August 24, 2006) - Providing design engineers with a device suitable for a multitude of automotive sensing applications, TT electronics OPTEK Technology has been selected by a major North American OEM to supply chassis sensors using the company's patented Autopad(TM) technology. Autopad is a non-contact precision inductive sensing technology capable of providing absolute position sensing as well as relative displacement feedback.

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 program, one of the current wins for OPTEK's Autopad(TM) technology, is anticipated 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(TM) 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 360º, 2x180º, 3x120º, and 4x90º. 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 -40ºC to +150ºC. Autopad technology features analog, ratiometric, PWM and digital outputs.
