Measurement reference point
All measurements are made from the reference point to the respective beam numbers. For the standard beam
counting direction this reference point is at the cable end of the light curtain. For the reverse beam counting
direction this point is the opposite end of the light curtain housing. The reference point is defined as the end of
the red light curtain housing (see Figure 11).

Note
: In an Object100 light curtain with a 25 mm pitch, only every 2
nd
physical lens is "active"!

Pitch and height measurement
The light curtain is designed with an active beam pitch of 10 mm or 25 mm. In either case the lens closest to the
connector end of the light curtain will always contain an active beam. The beam positions are a function of the
beam number and can be calculated as follows:
h = h
off
+ (n-1) x p
h
active beam position [mm] with respect to the reference point at the end
of the light curtain housing
