How should I wire the sensors and avoid trouble?

1.Produce a sufficient cross section with equipotential bonding between electrically conductive system components. Electrically conductive device carriers or DIN rails must be included in the equipotential bonding of the system. 
2.Install control cables and signal cables shielded.
3.If necessary, connect unused signal inputs with a defined potential or GND.
4.Please connect cable shields only on one side and at the amplifier with PE.

•   For devices in the field housing, connect the cable shield within the EMC cable gland to the metal housing.

•   For devices in DIN rail the cable shield housing connected to the rail by a PE-terminal next to the device.


5.Keep the cable lengths between the sensor and the measuring amplifier as small as possible.
6.When connecting components for a fieldbus system, only use the cables and connections specified for the respective bus system.
7.Do not route signal cables together with cables that transmit higher powers or high-slope signals. An intersection at an angle of 90 ° is permitted.
8.To avoid grounding problems, it makes sense to connect GND and PE at a defined point within the plant. Further connections (eg internally in single devices) can cause malfunctions.


Safety Instructions

In the event of recognizable damage or malfunction, put the device out of service immediately.
Switch off the supply voltage before opening the device.
The opening of the devices and any adjustment work inside the device should only be carried out by trained personnel.
Avoid touching printed conductors and electronic components as there is a risk of electrostatic damage.
Please observe the applicable regulations and safety regulations for low-voltage and high-current electrical systems as well as the national safety regulations.



Core Color and Connection

The wire assignment varies depending on the connector and cable type.

Maximum able length for sensors

There is no fixed maximum cable length. The better the line is shielded, the longer the line can be. On the basis of empirical values, a line length of up to 20 m is generally not critical.

The HAEHNE force sensors are supplied with a 5 m cable. If you want to extend the cable to a sensor, you can attach the option W with the specification of the cable length to the order code, e.g. W15 for 15 m cable length.
