Ambient temperature

Working temperature: -55 °C to +105 °C
depending on the fibre optic cable used (temperature ranges apply to the fixed installation of leads)
Ambient temperature limit switch:
-55 °C to +80 °C at T6
Depending on the fibre optic conductor selected, the enclosure heating at the installation site at the max. permissible ambient temperature must be assumed when calculating the max. temperature.

Description

The optical fibre bushing is used as an optical fibre cable entry into flameproof enclosures located in hazardous areas. They can also be supplied with plug-in connectors.

The optical waveguiders – also known as fibres – are made of glass and resist to mechanical, climatic, chemical and electromagnetic influences. The optical waveguide is most commonly used for carrying signals in the form of electromagnetic waves in the frequency range of visible light.

The type and structure of the cable determines its transmission properties.
