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 scanner safeguards irregularly shaped areas not suitable for a standard two-or three-piece safety light screen. It meets 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 scanner operates through the principle of diffuse reflectance (reflected light) to determine an object’s position through 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.
With a 0.36 degree lateral resolution, the scanner reliably detects objects in a zone up to 190 degrees 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.
