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
The AG4 safeguards irregularly-shaped areas not suitable for a
standard two-or three-piece safety light screen. It is also a 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 performs in applications
including area guarding, access/perimeter guarding and automated guided vehicle
(AGV) collision avoidance.
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.
With a 0.36 degree lateral resolution, the AG4
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. Advanced configuration capabilities allow operators to configure the AG4
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.
Key features of the AG4 Safety Laser Scanner include:
Highly flexible protective and warning fields
can be set to match the shape of the work area
Simple installation and easy-to-use software
Five LED diagnostic display presents system
status and diagnostics of devices without connecting to a PC
Eight individual protective and warning field
pairs can be configured
Configurable response time from 80 to 640 msec
RS-232 and RS-422 PC interface connection; USB
System 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
Two solid-state OSSD safety outputs (250 mA)
and two solid-state auxiliary outputs (100 mA)
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
