*2 The maximum distance of the stable detection range and the distance that can be detected under constant temperature when 2-point adjustment is used with no detectable object and the set value is set appropriately.
*3 Values obtained by converting the fluctuation range of the detection amount to the detecting distance under a constant environment using KEYENCE default settings.
*4 Detecting distance varies according to the material and size. See the characteristic diagrams for details.
*5 The value when using the 2-point adjustment function at a distance of 25% of the stable detection range with no detectable object and a standard detectable object at a distance of 50% of the stable detection range.

*1 The value when the operation mode is set to “Normal”, using the 2-point adjust function at a distance of 25% of the stable detection range with no detectable object, and a standard detectable object is placed at a distance of 50% of the stable detection range.
*2 150 μs and 300 μs are selectable only when the operation mode is set to “Normal”.
*3 The response time changes as follows when 4 or 8 units are selected as the number of interference prevention units. When set to 4 units: 5 ms / 10 ms / 40 ms / 170 ms / 700 ms (switchable), When set to 8 units: 10 ms / 20 ms / 70 ms / 300 ms / 1.2 s (switchable)
*4 Use a power voltage of 20 V or more when connecting 4 or more expansion units.
*5 When 1 or 2 units are added: -25 to +55°C -13°F to +131°F; when 3 to 10 units are added: -25 to +50°C -13°F to +122°F; when 11 to 16 units are added: -25 to +45°C -13°F to +113°F. When using two outputs, one unit is counted as two units. The prescribed values for the operating ambient temperature assume the sensor amplifier is mounted on a DIN rail installed on a metal surface. Exercise special care when installing the product in an airtight space.
*6 Supports IO-Link specification v1.1/COM2 (38.4 kbps).
*7 Ensure the power cable is no longer than 30 m 98.4' for M8 connector types and no longer than 20 m 65.6' with IO-Link connections.
*8 Output 2 and the external input are selectable.
*9 Counts as 1 output when connecting multiple units to the FS-MC8P/MC8N or NU Series.
