With more than 450 patents for photoelectric sensors, safety solutions, machine vision, and bar code scanners, SICK continues to lead the industry in new product innovations. The diversity of its product line allows SICK to offer solutions at every phase of production in the automotive, packaging, electronics, food and beverage, consumer goods, logistics, parcel/postal, and material handling industries.. SICK is one of the world’s leading manufacturers of sensors, safety systems and automatic identification products for industrial applications.
Industrial Sensors
SICK Industrial Sensors reliably sort, count, inspect, measure, recognize and verify the position, size and overall shape of objects. This vast array of industrial sensors encompasses photoelectric, inductive, capacitive and magnetic proximity sensors. Their
photoelectric sensors include cylindrical, compact, small and miniature series as well as zone control roller conveyor sensors and fiber-optic photoelectric sensors. Capacitive sensors are ideal for level and feed monitoring. From solid material, such as paper or wood... to granules or liquids, they reliably detect the status of the product during the production process and final inspection. SICK can always provide the right solution to meet your inductive proximity senor requirements – from cylindrical and rectangular standard sensors... to special sensors for explosive zones and harsh environments.

High-performance Sensors
Contrast sensors recognize differences in material brightness and color. SICK Contrast sensors detect minimum contrast levels at maximum speeds, such as print marks on foil, packaging and print products. They detect small 
differences in grey values between mark and background on matte, gloss or transparent surfaces.
Luminescence sensors recognize fluorescent markings, labels, threads, lubricants and adhesives. Color sensors identify and differentiate objects by color. Color sensors function using a special three-color method. Fork sensors combine the sender and receiver in a single housing. This ensures very reliable detection. SICK offers the most distance measurement products in the industry, providing more flexibility and value for its customers. You can detect distances or other dimensions, such as filling levels or positions precisely using SICK distance measurement sensors.

Safety Opto-electronic devices
Since their inception, SICK has led the world in opto-electronic Safety Solutions for hazardous machines and work areas. SICK continues to develop innovative point-of-operation devices, optical perimeter and area guards. Advanced functions of their safety
control devices include fixed, floating, and multiple point floating blanking, Presence Sensing Device Initiation (PSDI) and multiple configurable muting controls. SICK offers the most safety laser scanners on the market, providing you more application flexibility. Laser scanners are used for non-contact monitoring of a freely programmable area. No separate reflectors are required. Installation is simple because the sender and receiver are in a single housing. Safety light curtains are used for finger, hand protection and access protection. Depending on the type various machine functions are integrated or can be selected via safe control solutions.

Safety Switches
SICK products easily withstand harsh conditions, such as impact and vibrations. SICK safety switches are available in plastic or 
metal housings and are reliable over a long lifetime. Stricter safety regulations, and the need for tamper-proof safety at work, now make modern safety switches indispensable. Non-contact safety switches from SICK can be used for the safe monitoring of movable guards as well as for position monitoring

Vision Sensors
SICK's vision sensors are easy to use, rugged and reliable. From part inspection... to verifying presence... to color sorting and optical character recognition, SICK has a solution. SICK smart cameras can be programmed to read, inspect, locate, identify
and/or measure features in the acquired image data. A PC or laptop is used for application development and the camera operates stand-alone or as a part of factory network. The IVC-2D smart cameras come in standard VGA and high XGA resolutions and operate on gray scale images. The IVC-3D smart cameras are complete systems for high-speed capturing and analysis of true shape data. Measuring the third dimension provides knowledge about object height, shape and volume, independent of contrast. The Ranger and Ruler are high speed 3D cameras for advanced applications and tough industrial environments. The cameras measure object shape (3D) at high speeds at the same time as measuring other object features, such as gray scale and laser scatter (MultiScan). Measuring the 3rd dimension provides knowledge about object height, shape, or volume. In combination with the MultiScan technology, object information is provided by one single camera - decreasing solution complexity and cost.

Identification Solutions
SICK bar code scanners speed up logistics automation. Excellent reading performance ensures the process flow even when the bar 
codes are damaged or printed poorly. Their high scanning frequency enables high process speeds. This series also offers easy-to-use networking. The compact connection systems save space and costs. The stationary 2D code scanners from SICK have a multitude of uses. Whether 1D or 2D, or direct marked codes (e.g., laser, dot peening, ink jet) on metallic, plastic or on paper, they provide an ideal solution for nearly every application. They also offer multi-compatible connectivity. From the machine to the control system, they can be integrated in every environment. SICK hand-held scanners offer a cost-effective solution for non-industrial, general purpose 1D identification tasks. They support multiple interfaces, including USB, PS/2 and RS232 TTL, within a single scanner providing reliable identification of poor quality bar codes – no manual data collection needed.
