Why does mutual interference occur with Proximity Sensors?


If multiple Proximity Sensors are used, mutual interference occurs when the oscillating frequencies of the Sensors are close together. The oscillation widths will interfere with each other and malfunction or chattering will occur if the oscillating frequencies of neighboring Sensors are close together. To reduce this interference, Sensors with different frequencies are available to stagger the oscillating frequencies of the Proximity Sensors.
