Safety Light Curtains
Point of Operation Control
Description
Point of Operation Control (POC) safety light curtains are active
opto-electronic protection devices (AOPD) with resolutions of
14mm (0.55in) or 30mm (1.18in).
Allen-Bradley Guardmaster POC safety light curtains are self-
checking and belong to Safety Category 4. They have been designed
for industrial applications and are characterized by:
• High degree of reliability
• Maintenance-free components
• Practical size
• Sturdy modular construction
• Universal application possibilities
• Simple installation
Features
• Maintenance-free operation
• Control-reliable solid-state outputs
• State of the art microprocessor technology with custom-designed
ASICs (Application Specific Integrated Circuits)
• Easy assembly and alignment
• Quick-disconnect mini style connectors
• Long scanning range and high resolution
• Small housing cross section: 52mm x 55mm (2.05in x 2.17in)
• Fast response time ≤15ms
• Large excess gain
• Possibility to daisy-chain two sensors (to prevent personnel from
standing between protective field and the point of operation)
• Construction in compliance with EN 50100 Category 4
(self-checking)
• Tested and approved for USA, Europe, Canada and Japan
