Carlo Gavazzi - Sensores Fotoeléctricos con Supresión de Fondo

August, 2013 – Carlo Gavazzi is proud to announce the launch of a new range ofBackground Suppression (BGS) Photoelectric Sensors in the popular PA18 and PH18 housings. This allows for precise distance detection and distinction between a target and its background, with the flexibility of an industry standard housing. The detection principle is based on an Active Pixel Sensor (APS) CMOS array consisting of 64 x 1 sensors, where each pixel represents a specific position of the detected object. This offers an accurate sensing distance regardless of object color, allowing the sensor to be used on a variety of applications. These sensors have also been designed to avoid any false detection caused by lighting or electromagnetic interference, thus reducing system maintenance and increasing the application up-time. Furthermore, thanks to the efficient spherical lens design, this range has a longer sensing distance compared to the other background suppression sensors available on the market today. The PA18 and PH18 sensors can withstand water pressure up to 100 bar, cleaning agents, and disinfectants. They comply with all of the requirements for the ECOLAB and IP68/69K wash-down approvals. The sensors are well suited for applications in packaging, material handling, and food & beverage. Technical specifications include: Sensing range: 200 mm Power supply: 10 to 30 VDC Output current rating: 100 mA; Output voltage drop: 2.0 VDC @ 100mA Normally Open and Normally Closed outputs in the same housing PNP or NPN versions Short-circuit, reverse polarity, and overload protection Temperature range: -25°C to +60°C Pre-cabled or M12 quick disconnect IP68/69K ECOLAB approved, CE-marked and cULus approved according to UL508 For more information about these sensors, please click on any of the links below:  Product Brochure    Application Notes  Datasheet - PA18     1) Detecting Parts on a Conveyor  Datasheet - PH18    2) Part Level Detection  Tutorial - PA18    3) Bottle Cap Inspection  Tutorial - PH18    4) Presence Detection in a Tray  Cross Reference Guide      A Lifetime of Commitment to Automation

Sensores capacitivos - Control de objetos sobre una cinta transportadora

  Una de las caracteristicas principales de los Sensores Capacitivos, es que nos permite Sensar o "Ver" producto.  

  Podemos detectar si una caja de cereal esta llena ó vacia.  En el siguiente video podemos visualizar de una manera sencilla el uso de este tipo de sensor. 

 Es una linea de producción donde  se llenan con pastillas unas cajas de cartón.  El sensor lo utilizamos para detectar la caja y después para saber si lleva pastillas dentro.

Saludos y nos vemos en la siguiente nota...
