Allen-Bradley 440L AAC Single Beam Safety Light Curtain

The Allen-Bradley Guardmaster Area Access Control (AAC) Safety Single Beam is an economical, Type 4 single beam safety device in a robust IP67 housing. This single beam presence sensing device is designed for use around hazardous machinery or work cells, providing whole body detection in perimeter and access guarding applications. The IP67 environmental rating allows the AAC to be used in a number of operating environments where other safety opto-electronic devices would not reliably function. The AAC has a heated front window to help prevent the formation of condensation due to temperature variations, which allows the AAC to function in a variety of operating environments.

The latest addition to the GuardShield line of safety opto-electronic is offered in a both a short and a long range version. Sold as individual components, a single transmitter is paired with either a short range (0.5 to 20 meter) or a long range (15 to 70 meter) receiver.
