Banner Engineering AG4 safety laser scanner

The Banner Engineering 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 scanner safeguards irregularly shaped areas not suitable for standard two- or three-piece safety light screens. Compliant with Type 3 per IEC 61496-1/-2, Category 3 PLd per EN ISO 13849-1 and Safety Integrity Level (SIL) 2 per IEC 61508, it is suitable for applications including area guarding, access/perimeter guarding and automated guided vehicle (AGV) collision avoidance.

It uses the principle of diffuse reflectance (reflected light) to determine an object’s position via range and rotational angle. Once the protective and warning fields are configured, the position of the objects within the field of view is evaluated. If any are within a protective field, a safety stop signal is generated. The scanner 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.

Featuring a 0.36° lateral resolution, it reliably detects objects in a zone up to 190° from its fixed position. The scanner 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. Advanced configuration capabilities allow operators to configure the scanner with eight individual protective and warning fields. Users can quickly switch between configured field pairs, providing the flexibility to effectively protect personnel and equipment in diverse applications.
