Presence Sensing Safety Devices

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
