1.2 How to select a safety light curtain
•
Muting function
The safety light curtains are suitable for applications that require a
muting function. Safety light curtains PSEN op4B-T and PSEN
op4B-L are equipped with pre-assembled, pre-wired and pre-
aligned muting sensors. The muting sensors are designed for one
or two-way muting applications in an "L" or "T" shaped
configuration. Safety light curtains PSEN op4B-S are linear models
without integrated muting sensors.
- "L" shape configuration: is suitable for applications in which an
object leaves the danger zone in one direction.
- "T" shape configuration: is suitable for applications in which an
object moves in two directions.
- Linear models: Are suitable for applications on which the
sensors are intended to be positioned individually. A plug
connector enables the muting sensors to be connected simply.

Resolution, depending on the part of the body requiring protection.

Body protection
Type 4
The resolution (R) of a device is understood to be the minimum size
an opaque object must be in order to interrupt at least one of the
beams that form the sensing area.
As shown in Fig. 1, the resolution depends exclusively on the
geometrical properties of the lenses, the diameter and the centre
distance; it is independent of the ambient and operating conditions
of the safety light curtain.
