Instruction manual

1. Use the Sensor within the range in which the setting indicator (green LED) is ON (except D2 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 IP67G is the degree of protection which is defined according to the JIS (Japanese Industrial Standards).
 The IP67 indicates the same level of protection as defined by the IEC, and the G indicates that a device has resistance to oil.
 4. The Oil-resistant Component Evaluation Standards are OMRON's own durability evaluation standards.
 The Pre-wired Connector Model meets the degree of protection when it is correctly connected with an XS5[]R Oil-resistant Connector.
 The degree of protection is not satisfied with the part where there is no XS5FR Oil-resistant Connector connected and cable wires are uncovered.
 And as for the Pre-wired Models, the degree of protection is not satisfied with the part where cable wires are uncovered.
