*1. The response frequency is an average value. Measurement conditions are as follows: standard target, a distance of
       twice the standard target distance between targets, and a setting distance of half the sensing distance.
*2. When using any model at an ambient temperature between −40°C and −25°C and a power voltage between 30 and
       32 VDC, use a load current of 100 mA max.,
