New Safety Switch From SICK is Cost-Effective Alternative; Combining Maximum Safety With Easy Installation

LAS VEGAS - PackExpo 2003 -October 13, 2003 - SICK, the global leader in factory and process automation solutions, announced today its new safety photoelectric switch system used to safeguard hazardous areas on machinery and control access to restricted areas. The new L 4000 system is a Type 4, non-contact safety device that is able to monitor multiple doors simultaneously, while offering the highest level of safety.

The cornerstone of the L 4000 system is the UE 401 safety evaluation unit, which monitors the safe functioning of the sensor and generates a cut-off signal if the light path is interrupted. For maximum coverage, up to four individual sensor pairs, or up to eight cascaded sensor pairs, can be connected to the unit.

The L 4000 switches are available with a choice of metal or plastic bodies, with operating ranges from 0 to 60 meters. And, for the first time, they feature the safety switch optics and signal preprocessing built into standard M18 and M30 diameter cylindrical housings, thus ensuring simple mounting and alignment of the transmitter and receiver.

Rated to IP 67 and with an expanded temperature range of -20 to +55°C, the sensors are ideal for safeguarding machines and plants - including outdoor monitoring of doors and gates for pedestrian or vehicular access. The standard cylindrical housing makes the L 4000 sensors quick and simple to mount and the integrated design allows simple alignment of the transmitter and receiver.

During operation, a UE 401 safety evaluation device monitors the safe functioning of the sensors and the system generates a cutoff signal if the light path is interrupted. Supplementary integrated functions include external contact monitoring and restart interlock. Color LEDs provide constant information on the operating state and rapid fault diagnosis is possible using the visual signals and error messages on the seven-segment display of the UE 401.

With its low cost, compact size, installation flexibility and choice of options, the L 4000 Safety Photoelectric Switch Series is ideal for even the most complex safeguarding tasks, including the use of corner mirrors and outdoor applications.
