Product description
3.3 Enable zone and safe switch off
distance
Near range
Sensor
The output of the safety switch is only enabled on
activation within the enable zone. Outside the enable
zone, that is also in the near range, the output remains
switched off.
After activation in the near range, either the power
supply must be interrupted or the actuating element
must be placed at the safe switch off distance for more
than 2 s before enable is possible again.
The enable zone is dependent on the material and
shape of the actuating element. The use of different
actuating elements (material, shape) will result in
different enable zones.
At an ambient temperature of 20 °C, with the safety
switch surface mounted, with a standard plate as
per EN 60 947-5-2 (IN40-E0101K: 45 × 45 × 1 mm³,
IN40KE0109K: 60 × 60 × 1 mm³) the following enable
zone is typically achieved with different materials:
