Installation using nut
- Do not tighten the nut with excessive force. Be sure to install the toothed locked washer.
- In the case of the M8 threaded type, the allowable strength differs depending on the distance from the tip of the head. The following table shows the allowable tightening strengths for section B and section C shown in the diagram. (Section B starts from the tip of the head and its dimension is indicated in the table. Section C includes the nut on the head side. Therefore, if the nut extends
into section B even slightly, the strength of section B is applicable.)
- The following allowable tightening strengths are applicable when the washer is installed.

Installing small-diameter sensor
- Please use the sensor after confirming the installation distance by following (a) and (b) with an actual detection object when you install.
(a) |
The detection distance receives the influence by the material of the detection object, thickness, shape, and the size. So, the detection object is brought close to the front side of the sensor and detection distance (S) is measured. For the effect of the material, see the graph, "Correlation between sensing object size and sensing range". |
(b) |
Please decide installation distance (Sa) with S × 70% or less after measuring sensing distance(S). |
- Please install the sensor to come within the range of (Sa) when the detection object moves from vertical direction.
- Please install the sensor to pass within the range of (Sa) when the detection object moves from horizontal direction.
- When using the sensor, refer to the "Standard sensing object" specified in the specifications and the graph, "Correlation between sensing object size and sensing range".
Distance from surrounding metal
- As metal around the sensor may affect the sensing performance, pay attention to the following points.
Influence of surrounding metal
- The surrounding metal will affect the sensing performance. Keep the minimum distance specified in the table below.
- When mounting the sensor using a nut, use the nut and washer provided with the product.
- The type of the provided nut varies in different models. See the external dimensions diagrams for the detail of the shape.

Notes:
1) |
When sensors that are not compatible with IO-Link are used or when IO-Link compatible models are used as ordinary sensors, they operate in the standard I/O mode (SIO mode). |
2) |
The operation mode can be changed by the IO-Link communications. The timer function of the output can be set up by the IO-Link communications. |
