Sensors

Bar code scannerS Bar code reading devices are indispensable forfast and accurate object identification. Solutions from SICK include fixed position laser and vision-based bar code scanners for controlling material flows on conveyor systems, and mobile hand-held scanners for rapid and reliable detection of linear bar codes or 2D codes. SICK now offers a wide range of products for both stationary and mobile identification tasks.
roller conveyor sensors These non-contact sensors, which were specially developed for handling systems, detect the conveyed object from between the rollers. The detection signal is evaluated in the logic unit and the electropneumatic cylinder is actuated via the valve. Use of these sensors for accumulating conveyor systems do not have the need for additional control elements
inductive sensors An inductive proximity sensor comprises an LC oscillating circuit, a signal evaluator, and a switching amplifier. The coil of this oscillating circuit generates a high-frequency electromagnetic alternating field. This field is emitted at the sensing face of the sensor. If a metallic object (switching trigger) nears the sensing face, eddy currents are generated. The resultant losses draw energy from the oscillating circuit and reduce the oscillations. The signal evaluator behind the LC oscillating circuit converts this information into a clear signal. High switching frequencies and high continuous currents characterize many SICK inductive sensors. They are available as DC 2-wire conductors, DC 3-wire conductors, DC 4-wire conductors, AC/DC 2-wire conductors, AC 2-wire conductors and NAMUR sensors in accordance with EN 50 227.
ultrasonic sensors Ultrasonic sensors are primarily utilized when the target or environment is optically difficult and when a large measurement area (spot size) is required. Typical environments include: * Dust, dirt, fog * Uneven and shiny surfaces, mesh and webbing * Clear materials and liquids, etc.
VISION SYSTEMS Machine vision sensors integrate imaging technology, lighting, display and evaluation hard- and software in one compact housing. The user-friendly, out-of-the-box integrated operating software ensures that no additional programming knowledge is necessary. The integrated display and lighting allow a fast and easy start-up compared to that of standard camera systems. Machine vision sensors are often used for detecting or sorting colors, checking contour, or for character recognition, especially in the food and beverage, pharmaceutical and automotive industries.
