The new W11-2 series of photoelectric switches from Sick is equally suitable for standard and special applications as factory automation. The pin-point sensor technology is incorporated in the series, as well as a large number of device variants are available. Adapted for multifarious tasks, the series is suitable for applications requiring reliable object detection, universal integration capability and user-friendliness.
The W11-2 sensor series offers a large variety of device variants and sensor technologies. The WTB11-2 photoelectric proximity switch with background suppression and enhanced scanning distance contains an ASIC specially developed by Sick for optoelectronic sensors. The same applies for the WTF11-2, whose foreground suppression ensures reliable object detection irrespective of the surface.
The ASICs in the two sensors allow accurate electronic adjustment of the scanning distance and precise stable definition of the foreground or background area to be suppressed. The family of scanners is rounded out by the WTE11-2 energetic photoelectric proximity switch. With its performance data, the WL11-2 photoelectric reflex switch is intended for tasks in handling and warehousing systems.
The WL11G-2, based on the same technological platform, is suitable for the reliable detection of transparent objects, e.g. PET bottles or transparent foils. The WSE11-2 through-beam photoelectric switch is suitable for applications requiring larger functional reserves or very long ranges.
The rugged housing design of the W11-2, together with the reinforced mounting holes, gives the sensors a high level of immunity to heavy mechanical vibrations. The permissible operating temperature lies between -30°C and +60°C. Chemical resistance has been inspected and confirmed in comprehensive tests using the materials produced by Ecolab. Regarding the effect of electromagnetic fields, the devices’ EMC lies well above CE requirements, i.e. sources of interference of all types in the operating environment are electronically suppressed and thus, reliably cut out.
The new W11-2 series is suitable for machine constructors, OEMs and users in the detection of transparent to jet black objects. The space-saving, compact housings as well as the uniform housing, mounting and connection features across the entire series, including dovetail mounting and rotating M12 plug with intermediate positions, offer universal integration potentials for most machine sizes. The devices are easily and rapidly mounted and connected. The operating mode and switching state of the W11-2 sensors are indicated by means of two easily visible 360° status LEDs on the housing.
The W11-2 is a suitable series of photoelectric switches for many standard applications as well as for challenging special solutions including those in automation segments, e.g. handling and warehousing systems, packaging machines and filling lines.
