Specifications
DC 3-wire Models
Note 1.
The response frequency is an average value. Measurement conditions are as follows: standard sensing object, a distance of twice the
standard sensing object length between sensing objects, and a set distance of half the sensing distance.
2.
For USA and Canada: use class 2 circuit only.
