EZ-SCREEN (Light Curtain)
EZ-SCREEN® - Point 1 Beam
RANGE
– 0.8-20 m
– 15-70 m
EZ-SCREEN® - Grids 2,3,4 Beam
RANGE
– 0.8-20 m
– 15-70 m
EZ-SCREEN® – Type 4
Two Resolutions
14 mm models 0.1 m to 6 m (4" to 20')
30 mm models 0.1 m to 18 m (4" to 60')
Lengths150 mm to 1800 mm
Response Times30 mm models = 9 ms to 32 ms 14 mm models = 11 ms to 56 ms
EZ-SCREEN® Type 2
Type 2 is NOT “half-as-safe” as a Type 4, but:
EZ-SCREEN® Type 2
“Type 2” versus “Type 4”

Periodic external TEST may be needed
to maintain safety
Less resistance to faults and maintain the safety function

Entry
AG4 Safety Laser Scanner
Protective and Warning Fields – Field Pairs
Material transfer (robot) cell
Area behind robot requires additional
safeguarding (example, fencing,
hard guarding, presence sensing device)

Installation Considerations
AG4 Safety Laser Scanner
At a minimum, a risk assessment must address: Unmonitored Areas
– Behind and to the sides of the scanner– "Shadowing" within the Protective Field– Needle-shaped and cone-shaped contours
Adjacent Scanners– Could add 40 ms to
response time
Application Examples
AG4 Application Overview
Two-Hand Control
Diverse redundant and self-checking
– Dual microcontrollers
– Multiple optical paths The patented diverse-redundant,
self-checking design will detect an internal safety-critical circuit fault and immediately switch its outputs to the OFF state.
Self-Checking Optical Touch Button
