Banner laser system guards irregular shaped areas

The AG4 Safety Laser Scanner is designed to deliver safety, simplicity and versatility in a single, compact optical device, effectively safeguarding irregularly-shaped areas not suitable for a standard two- or three-piece safety light screen.
It is also an excellent replacement solution for high-maintenance safety mats that are routinely damaged by repetitive operation or adverse environments. By meeting all requirements for Type 3 per IEC 61496-1/-2, Category 3 PLd per EN ISO 13849-1, and Safety Integrity Level (SIL) 2 per IEC 61508, the AG4 delivers superior performance in applications including area guarding, access/perimeter guarding, and automated guided vehicle (AGV) collision avoidance.
Featuring a 0.36° lateral resolution, the AG4 reliably detects objects in a zone up to 190° from its fixed position. The AG4 provides selectable protection field resolution of 30, 40, 50, 70, and 150 mm with ranges up to 6.25 m, while its warning field provides coverage of up to 15 m.
The AG4 Safety Laser Scanner uses pulses of Class 1 infrared laser light to locate the position of objects in its field of view, effectively protecting personnel by safeguarding both stationary and mobile hazards within a user-designated area.
The AG4 Safety Laser Scanner operates through the principle of diffuse reflectance (reflected light) to determine an object's position via range (measured distance) and rotational angle. Once the AG4 protective and warning fields are configured, the position of the objects within the field of view are evaluated. If any are within a protective field, a safety stop signal is generated from the scanner.
The AG4 can additionally be configured so that an intrusion in the warning field triggers an auxiliary output. This may be used to slow a mobile vehicle, flash a light, or initiate other actions to warn an individual who enters this field.
