*1. Use the Sensor within the range in which the setting indicator (green LED) is ON (except X2 Models).
*2. The response frequency is an average value.
Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object,
and a set distance of half the sensing distance.
*3. The residual voltage is 5 V. Make sure that the device connected to the Sensor can withstand the residual voltage.
