General Specifications: D Models

d sensor graphThe output voltage function for D model sensors includes a near side region where the voltage rises with increasing distance, an optical peak region, and a far side region where the voltage output decreases with increasing distance. Operation in the near side region gives high sensitivity with limited operating range. Operation in the far side region gives moderate sensitivity with greater operating range.
