●Design
Sensing Object Material
The sensing distance varies greatly depending on the material of the
sensing object. Study the engineering data for the influence of
sensing object material and size and select a distance with sufficient
leeway.
Size of Sensing Object
In general, if the object is smaller
than the standard sensing
object, the sensing distance
decreases.
• In general, if the

Power Reset Time
A Sensor is ready for detection within 100 ms after turning ON the
power. If the load and Sensor are connected to separate power
supplies, design the system so that the Sensor power turns ON first.
