2Introduction2.1Product OverviewThe zForce AIR Touch Sensor is a laser light based touch sensor that can be integrated and used in various
applications. The sensor characteristics are high scanning frequency, low latency, good touch accuracy and the fact
that it can be used on any surface or even in mid air. zForce AIR Touch Sensor can be connected to the host system
through a standard connector and communicatethrough a standardI2C or USB interface.
2.1.1Main Features•Enables touch on any surface or in mid air
•Dual touch support
• High scanning frequency – up to 200Hz or more depending on sensor length
•Low touch latency
•High touch accuracy
•Idle mode for reduced current power consumption
•Configurable touch active area
• I2Cand USB interface
•Standard 5V power supply
2.2Product VariantsIn order to fit in a wide range of applications, the zForce AIR Touch Sensor exists in two types and a number of
different lengths.
If the variant you are interested in is not availablefor purchase from your distributor, please contact the
distributoror a Neonode sales representative (refer to www.neonode.com1)for more information.

2.2.1Sensor OrientationThe zForce AIR Touch Sensor is available in two types, one where the active area emerges straight out from the
sensor (0° type) and one where it emerges out from the sensor at a 90° angle (90° type). This enables both vertical
and horizontal integration.
0° Type
90° Type
2.2.2Sensor LengthThe Touch Sensor is available in 43 different lengths. The length affects the Touch Active Area (TAA) in both X and Y
directions.
