Azoteq’s industry-leading sensitivity and robustness enable many new applications for proximity and touch. Azoteq now offers the lowest cost capacitive solutions to replace mechanical switches

Austin, TX (PRWEB) May 16, 2013

Azoteq, the world leader in capacitive proximity sensing, announced breakthrough pricing for selected capacitive proximity and touch controllers. With pricing of less than $0.025 per switch or channel capacitive switches can now replace mechanical switches in many applications. In addition designers get proximity detection of over 300 mm using practical electrodes.

Azoteq combined breakthrough levels of sensitivity, Signal to Noise Ratio (1000:1) and RF immunity into cost-effective capacitive controllers. These benefits relax the common design constraints normally imposed on designers, and the automatic tuning algorithm ensures that no calibration is required in manufacturing. This allows designers to use thick overlay materials of up to 50 mm or more and touch keys in extremely small spaces. With ProxSense® a touch key is easily realized with a pad on a PCB. Proximity detection is natively offered on all touch key controllers, opening up possibilities for more intuitive user interfaces. This includes such as wake-up from standby, pre-emptive menu selection and automatic backlight illumination.

ProxSense® was developed and patented from the ground up using novel analog design techniques for ultra sensitive capacitive measurements. The result is a proximity and touch controller that can sense changes of 20 atto farads in projected capacitance mode and 200 atto farads in self capacitance mode. In contrast to common perception, Azoteq has proven that long range can reliably be achieved with projected capacitance. R&D in novel micro-electronic designs allows for this groundbreaking sensitivity whilst maintaining industry-leading ESD immunity and low current consumption.

“Azoteq’s industry-leading sensitivity and robustness enable many new applications for proximity and touch. Azoteq now offers the lowest cost capacitive solutions to replace mechanical switches”, said Frederick Bruwer, CEO of Azoteq.
