The posi ion of he ligh beams is
indica ed by a marking on he
housing.
Synchronisa ion be ween sender
uni and receiver uni is achieved
op ically, by means of a pre-defined
encoded sequence, hus elimina ing
he need for galvanic connec ion
be ween sender and receiver.
The MSLZ variant
The MSLZ ligh barrier, like he MSL
is a con ac less pro ec ion
ins alla ion – bu wi h one passive
side and one ac ive side (
fig. 2
). I is
sui able for access con rol and
danger zone pro ec ion wi h a pas-
sive mirror side, and a maximum
dis ance of 7.5 m. The MSLZ fulfils
he pr EN 50 100 (pr EN 61 496)
regula ions, safe y ca egory 4.
