EZ-SCREEN SLS emitters and receivers are also available in cascadable models. These models can be used as stand-alone
light screens, or can be cascaded up to four systems. The cascaded sensor pairs can be any length, any number of beams,
or have different resolutions (14 mm and 30 mm), as long as each emitter matches its own receiver.
NOTE: EZ-SCREEN SLS.. (standard) or SLSC.. (cascadable) models can be used as the end sensor pair
of a cascade chain.
Special cabling is not required, but the double-ended 22 awg cordsets are recommended. Pigtail QD models may be used to
reduce the number of required cables. Response time is dependent on the number of beams in the light screen and the light
screen’s position in the cascade. Maximum system response time can be calculated easily for these cascaded systems, in
two ways:
Individually for each light screen in the cascade (separation distance is calculated for each light screen in the cas-
cade), or
Based on the worst-case maximum for the entire cascade (all light screens in the cascade have the same separation
distance).
The receivers are shown using the EZA-MBK-21 "L" mounting bracket.
EZ-SCREEN SLS SLS models (with Inverted Display) can be used as the end sensor pair.
