EZ-SCREEN
Features
• An optoelectronic safeguarding device
• Standard and cascadeable models available
• Compact package for smaller production machines,
robust for large power presses
• Creates a screen of synchronized, modulated
infrared sensing beams. Choose from two
resolutions in 12 sizes, in 150 mm (6") increments:
- 14 mm (0.55") resolution models with defined
areas from 150 mm to 1.8 m (6" to 71")
- 30 mm (1.18") resolution models with defined
areas from 150 mm to 1.8 m (6" to 71")
• Optional remote Test input terminals for simulating
a "blocked" condition (available on some emitter
models)
• Easily configured Reduced Resolution (Floating
Blanking)
• Three-digit display provides diagnostic information
and indicates number of beams blocked
• Zone indicators identify blocked beams
• FMEA tested to ensure control reliability
• Receiver LEDs provide system status and emitter/
receiver alignment indications
• Highly immune to EMI, RFI, ambient light, weld
flash, and strobe light
• Two-piece design with External Device Monitoring
• Vibration-tolerant, factory burned-in emitter and
receiver circuitry for toughness and dependability
• Up to four pairs of emitters and receivers of
different lengths can be cascaded (SLSC..
