Sick safety camera systems for machine guarding

The V300 WS Extended, and the V200 WS Extended, safety camera systems for machine guarding, can monitor protective areas of up to 2.25 m², with a range of 2.12 m.

The safety sensor signals within 20 ms and stops machine movement when the monitored area is accessed during operation.

The two cameras enable engineers to comply with safety levels up to SIL 2 and PL d, in line with European safety directives IEC 61508, PL and EN ISO 13849.

The camera is mounted using two screws, and a single cable is required to provide electrical connectivity. Mounted in a corner, the sensor generates a field that reaches the reflector strip mounted opposite the device. The entire length and breadth of the reflector strip is monitored with a choice of resolutions, including 20, 24 or 30 mm.

The protective field can be easily adapted to the application during commissioning to guard different shapes, angles and intrusions such as cables and supports.

Simple programming of this system is carried out with intuitive single-button operation, via a four-LED display. The LEDs indicate the status of the safe switching outputs, external device monitoring, the reset button and the teach-in button. The assignment of the LEDs permits targeted corrective work, minimising time spent handling servicing activities. In addition, the LEDs provide virtualisation of reflector strip detection for each sector.
