<p>An anti-entrapment system for preventing an object from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device. The sensor has first and second flexible conductors separated by a separation distance. The conductors have a capacitance dependent on the separation distance. The sensor has a compressible dielectric element interposed between the conductors. The capacitance of the conductors changes in response to the separation distance changing as a result of the dielectric element compressing in response to a first object touching the sensor. The capacitance of the conductors changes in response to a second conductive object coming into proximity with at least one conductors. A controller controls the translating device as a function of the capacitance of the conductors to prevent the translating device from entrapping either of the first object or the second conductive object.</p>
