The PR Series proximity sensors have a long life cycle and high reliability with simple operation. They use dedicated IC (DC 3-wire) to enhance noise resistance. The 2-wire DC models have a residual voltage of 4 VDC (max.), a control output range of 2-100mA, and an operation voltage of 10-30 VDC. The 2-wire DC models are also polarity free. The DC models have reverse polarity protection and overload protection, and all models have surge absorption. Operations are confirmed easily by a red LED indicator lamp. The PR Series is used for a wide range of applications for replacement of micro switches and limit switches.
