Pay attention to the following description when operating the MSK320SKF sensor with ATEX approval in the EEx-hazardous area

The maximum electrical and mechanical limiting values specified in the Technical data must not be exceeded. The following characteristic safety values apply to the MSK320SKF sensor:

inspection certificate

EC type-examination certificate TPS 13 ATEX 47828 001 X for Sensor MSK320SKF of 06-21-2016. The inspection certificatewill be provided on request.

Hint The sensor must only be operated in the specified operating temperature range of -40 ... +120 °C

MSK320SKF ATEX option
gravure (only with ATEX version)

Description of a safety circuit taking the example of (see next page)

The operating voltage is connected to the safety barrier. The safety barrier limits the current flowing into the EEX circuit to ≤350 mA and the voltage to ≤9 V.
The output signals are routed to the optical separation provided to this purpose. This ensures that no energy can enter the sensor through this path.
