The dielectric constant of an object affects capacitive sensing; therefore, the sensing distance is governed by the object's

Capacitive sensing works by detecting changes in capacitance caused by a nearby object polarizing in the sensor’s electric field. The amount of polarization, and thus the change in capacitance, is driven by the object's dielectric constant (relative permittivity). For a given sensor geometry, a higher dielectric constant increases the capacitance more for the same distance, making the object detectable at a greater distance. Conductivity, magnetic properties, or temperature aren’t the primary factors setting the sensing distance in this context. So the distance the sensor can detect is governed by the object's dielectric constant.
