If liquids with aggressive ingredients are used for cleaning,
please check whether the product used is compatible with the
material of the sensor (refer to chapter "Technical data").
The user must evaluate and design the safety chain in ac-
cordance with the relevant standards and the required safety
level.

cable. The downstream control element must recognise this state as
LOW. A safety PLC must detect this state.
2.6 Response time (reaction time)
The response time depends on the hight of the protected field, the
resolution and the number of light beams.
