Presence Sensing Safety Devices

Safety Light Curtains

Perimeter Access Control

Description

Multi-beam safety light curtains from Rockwell Automation are

infrared protection devices with 1 to 4 infrared beams. They operate

on the through-beam principle, consisting of a sender and receiver

unit and are suitable for access control and perimeter guarding.

The PAC fulfils the pr EN 50100 requirements, safety category 4, in

that it is a self monitoring device.

• Integrated evaluation with state-of-the-art electronics and

especially developed ICs (ASICs)

• Beam coding for high interference immunity

• Actively monitored semiconductor outputs

• Mini style quick disconnect connectors

• Fast response time

• Large signal reserve (factor 2)

• Optical synchronization of sender and receiver units

• Multiple safeguarding by means of corner mirrors and columns

• Operating modes:

• Electronic Device Monitoring (EDM)

• Restart Interlock

• Muting configuration available

The devices were designed for industrial applications and offer the

following advantages:

• Beam coding for optimal interference immunity

• Adaptability for safe PLC

• Robust modular construction

• Universal application possibilities

• Simple installation
