steute RF IS M nb-ST Wireless Inductive Sensor Instruction Manual

steute RF IS M nb-ST Wireless Inductive Sensor

Product Information

The RF IS M… nb-ST is a wireless inductive sensor that is used for contactless detection of metallic parts. The device is connected to the universal transmitter RF 96 ST or RF I/O. It has low tightening torques and the sensor part consists partly of ferrite which makes it very shock-sensitive. The device comes with 2 mounting nuts, 1 mounting and wiring instructions, and a carton.

Use of the mounting and wiring instructions

Target group: authorised and qualified staff. All actions described in these instructions may only be performed by qualified persons who have been trained and authorised by the operating company.

1. Read and understand these mounting and wiring instructions.
2. Comply with the valid occupational safety and accident prevention regulations.
3. Install and operate the device.
   Selection and installation of devices and their integration in control systems demand qualified knowledge of all the relevant laws, as well as the normative requirements of the machine manufacturer. In case of doubt, the German language version of these instructions shall prevail.

Scope of delivery

• 1 device
• 2 mounting nuts
• 1 mounting and wiring instructions, carton

Product Usage Instructions

1. Read and understand the mounting and wiring instructions provided.
2. Comply with the valid occupational safety and accident prevention regulations.
3. Install and operate the device. Only qualified persons who have been trained and authorized by the operating company should perform all actions described in the instructions.
4. Selection and installation of devices and their integration in control systems demand qualified knowledge of all the relevant laws, as well as the normative requirements of the machine manufacturer. In case of doubt, the German language version of these instructions shall prevail.
5. When operating wireless inductive sensors of the same design side by side, ensure that they are mounted at appropriate distances to avoid reciprocal influence.
6. Ensure that the minimum distance to/of a conductive surface is 3 x sn opposite the active surface when mounting the device.
7. Clean the device with mild, non-scratching, non-chafing cleaners in case of damp cleaning. Do not use aggressive cleaners or solvents. Routine maintenance includes removal of all dirt particles, checking of enclosure and connecting cable for damage, and checking function.
8. Dispose of the device in accordance with national, local, and legal regulations.

Intended use

The device is used for contactless detection of metallic parts. The device is connected to the universal transmitter RF 96 ST or RF I/O.

Mounting notes
The wireless inductive sensors are installed non-flush only. For the installation, observe the following conditions, »Free space«, »Reciprocal influence«, »Tightening torque«, and »Front surface«.

Free space
With wireless inductive sensors, the function principles are based on the influence of a stray electromagnetic field. Because this stray field does not only interfere with the object to be dectected, but also with other conductive objects and also interferes with other wireless inductive sensors, observe some mounting conditions. Opposite the active surface, the minimum distance to/of a conductive surface is 3 x sn.

• Free space around a cylindric non-flush wireless inductive sensor and distance to an opposite conductive surface.

Reciprocal influence
If wireless inductive sensors of the same design are operated side by side, the oscillators for generating an electromagnetic field may interact with each other. This effect is undesirable and can lead to faulty operations. To avoid this effect, observe the distances of the adjacent proximity switches as shown below.

• Mechanical strength

Tightening torque
The wireless inductive sensors have only low tightening torques:

• M8: 8 Nm
• M12: 10 Nm
• M18: 25 Nm
• M30: 75 Nm

Front surface
The sensor part consists partly of ferrite. It is very shock-sensitive. Never use its front surface as an end stop.

Cleaning

•  In case of damp cleaning: use water or mild, non-scratching, non-chafing cleaners.
• Do not use aggressive cleaners or solvents. Clean enclosure on the outside only. Clean enclosure with household cleaning agents. Do not use compressed air to clean.

Maintenance

With rough conditions, we recommend routine maintenance as follows:

1. Removal of all dirt particles.
2. Checking of enclosure and connecting cable for damage.
3. Check function.

Disposal

• Observe national, local and legal regulations concerning disposal.
• Recycle each material separately. Dispose of contained batteries correctly.
