Front Panel
The front panel material and thickness influence the projected capacitance field. Each
material type is defined with a dielectric constant, known as epsilon (
εr). The higher εr is,
the easier the field can pass through material.
For example (see Figure 29), if the proximity distance without any panel is tair0, it becomes
tair1 when a panel is inserted between the sensor and the hand. tair1 is the distance between
the hand and the front panel, and Ttotal is the total distance between the hand and the
sensor. tair1 is lower than tair0 but the Ttotal is higher than tair0.
Figure 29.
