PROXIMITY SWITCH ASSEMBLY AND METHOD HAVING ADAPTIVE TIME DELAY |
摘要 |
A proximity switch assembly and method for detecting activation of the proximity switch assembly is provided. The assembly includes a plurality of proximity switches each providing a sense activation field and control circuitry processing the activation field of each proximity switch to sense activation. The control circuitry monitors the signal responsive to the activation field, determines a rate of change in signal amplitude for each signal, and generates an adaptive time delay based on the control circuitry. The control circuitry further detects a peak amplitude of the signal and determines activation of the switch after expiration of the time delay following the peak amplitude detection.
