The W11 series of photoelectric switches expanded by universal voltage version

SICK has rounded out its W11 series with the WL11 UC, suitable for both direct and alternating voltage supplies – a robust photoelectric reflex switch that offers flexible use. Features such as its range of 7 m, high detection reliability even with objects with highly reflective surfaces, and the electrically safe isolated switching output open numerous industrial areas for WL 11 UC use, including the packaging industry, or storage and conveyor technology. By complying with the EN 61000-6-3 CE standard for interfering radiation, the sensor is also of interest for applications in residential and commercial areas, e.g. as a sensor for controlling doors and gates.

The W11 UC can be supplied with 24 - 240 V DC as well as with 24 - 240 V AC. Like the other devices of the W11 series, the new photoelectric reflex switch also has a red-light transmitter LED. Thus the sensor can be easily and precisely aligned on objects at distances of up to 7 m. The robust ABS plastic housing, the scratchproof PMMA optics, and the enclosure rating of IP 65 ensure a high level of WL 11 UC stability during use. The maximum switching frequency is 20 Hz so that rapidly moving objects can also be reliably detected. Even objects with reflective surfaces are reliably detected thanks to the standard integrated polarisation filter.

Open for doors and gates

With its universal voltage supply, great robustness, simple installation, and compliance with the EN 61000-6-3 CE standard for interfering radiation, the WL 11 UC fulfils all the important requirements for use with doors and gates. The sensor is thus also suitable for other wider-ranging areas of application, in addition to the classical industrial fields.
