Influence of ambient
temperature
Maximum 0.1 %/K
Switch-on delay
< 2 s until correct switch status is set. Prior to that, the switch outputs are in a blocked state.
Switching delay
• 0.5 s when sensor is covered
• 1.0 s when sensor is uncovered
• IO-Link communication: 0.3 to 60 s configurable
• Can be ordered as option: 0.3 s; 1.5 s or 5 s (when sensor is covered or uncovered)
