[In Chinese standard (GB 4584)]
In case slide of press machine can be stopped where you would like to, safety distance S
can be calculate by calculating formula 1.
Equation 1
S = K × T + C
`] {""^
Minimum required distance between the sensing area surface and the danger-
ous parts of the machine.
`%* ]G] {""Y ^
In case the intrusion direction is horizontal to the sensing area, Taken as 1,600 (mm/
sec.) for calculation. In case the intrusion direction is perpendicular to the sensing area,
Taken as 2,000 (mm/sec.) for calculation when the safety distance is 500mm/s or less
and taken as 1,600 (mm/sec.) for calculation when safety distance is 500mm/s or more.

In case the slide of press machine can not be stopped in your desire point, the safety
distance S can be calculated from formula 2.
