Application with four muting sensors:
Application with two muting sensors:
In the above application with two muting sensors, the crossing point of beems from two muting
sensors (A and B) is set behind the protective area of the light curtain. This arrangement
prevents the light curtain from being muted by a person passing through the crossing point.
D1,D2,D3: minimum distance so that the muting sensors keep active the
request; it depends on the parcel length:
D1,D2,D3 < L
d
1
:
necessary maximum distance so that the muting request is
accepted; it depends on object speed:
d
max
[cm]= v[m/s] x 3[s] x 100
This distance must not allow both sensors and the muting
cycle with the passage of a person.
