V300 WS model of safe camera systems from Sick
Sick offer sales and distribution services for a range of safe camera systems suitable for work stations safety monitoring applications. The V300 WS model of safe camera systems from Sick is space-saving, rapid and suitable for hand protection applications. These safe camera systems can be used for Category 3 protection of hazardous points-of-operations in compliance with EN 61496-1 standards (SIL2 according to IEC 61508). The access openings on assembly, handling and industrial robots, inspection machines, and other manually operated work stations involving cyclical or occasional access can be monitored with these vision systems, with optimum safety and without barriers.
Safety on the edge
The V300 WS safe camera system is an electro-sensitive and protective tool that works on the basis of the image-processing technology. The sensor’s illumination and receiver are integrated in a single housing – as are its supplementary Reset and Electronic Device Monitoring (EDM) functions. The compact triangular housing allows mounting in or on the corner of a work station’s grooved section frame that is in a location in which the sensor is largely protected against impacts or misalignment. A reflector is attached on the opposite side of the mounting location. With its 110° angle of view, the camera system automatically detects the entire length and breadth of the reflector area and aligns the monitoring field on it with a resolution of 20 mm. The V300 WS safe camera system responds within 20 ms if anyone reaches into the machine while it is running, and immediately stops the process.
Permanent self-monitoring
In order to ensure maximum safety and availability, the V300 WS safe camera system permanently monitors the reflector strip for dirt, holes, damaged areas or objects placed upon it. When a problem has been detected it can be pinpointed through the LED indicators, because each of the four indicators monitors a different segment within the field of view of the V300 WS. If the reflector strip can no longer be cleaned or is too damaged, the full functionality of the V300 WS can rapidly be restored by simply attaching a new reflector strip.
Opens up barrier-free monitoring opportunities
Ergonomic workplaces can be achieved with the V300 WS safe camera systems distributed by Sick that offers comfortable and effective work environment. The device is easily and dependably mounted with just two screws. Even as a single sensor, the V300 WS safe camera system generates a diagonal protective field with a maximum range of 1.41 m, to protect openings with dimensions of 1m x 1m. If the access opening is larger, it is possible to connect two devices to one another through the standard synchronisation input and thus double the size of the protective field. Two safe camera systems are also the perfect solution when two adjoining sides require protection: there is no need for a central brace on the corner junction so operators can gain access to the machine without any barrier, for example to insert or remove larger workpieces.
Safety in the appropriate category
The V300 WS safe camera systems supplied by Sick are suitable for the Safety Categories 3 and SIL2 not covered by light curtains. For Category 2 protection, Sick’s V200 WS model of safe camera systems can be used.
