Pepperl+Fuchs OCT300-M1K-N2

The Diffuse mode sensor is a critical component in industrial automation and process control applications. These sensors utilize a light beam to detect the presence of objects by reflecting light off their surfaces. With their ability to function effectively in challenging conditions, they are ideal for use in areas where dust and gases are present.

This product family is particularly suited for applications in industries such as chemical processing, oil and gas, and food production, where safety and reliability are paramount. The adjustable sensor head allows for versatile installation options, while the scratch-resistant mineral glass lens ensures longevity and consistent performance even in abrasive environments.

Installation, commissioning	The associated apparatus must, as a minimum, fulfill the requirements for degree of protection ia and for Groups II or III, as appropriate for the operating conditions. Due to the possible risk of ignition that can occur as a result of faults and/or transient currents in the equipotential bonding system, galvanic isolation in the supply and signal current circuit is preferred. Associated apparatus without galvanic isolation may only be used if the appropriate requirements as set out in IEC 60079-14 are met. This certificate does not guarantee that the components installed in the partition isolate the zones completely from one another. Appropriate measures must be taken when the partition is set up to ensure the zones are completely isolated.
