Econo-Vue Photoelectric Sensors

Nov. 24, 2009
Pepperl+Fuchs popular Econo-Vue family of photoelectric sensors are now available in AC/DC versions, in addition to the existing DC types.  The Econo-Vue’s universal supply voltage is significant to machine builders and users in that it allows them to stock a single sensor that can be used for AC or DC applications.  Additionally, AC supply sensors could result in longer runs of interconnected sensors than is otherwise possible for DC types only. As a whole, the Econo-Vue series is available in five sensing modes and over 100 models to suit varied application requirements.“With DC versions that are up to 50% shorter than competitive models and AC/DC versions that are the shortest M18 cylindrical photoelectric sensor housings available on the market today, Econo-Vue sensors are more likely to fit into space-critical equipment or installations. For example, when mounted through the sidewall of a conveyor the Econo-Vue protrudes less than other M18 cylindrical sensors, so conveyors or equipment can be placed closer together and ultimately take up less space,” says Jeff Allison, Product Manager.Every Econo-Vue sensor includes a flush-mount bracket that allows for a simple, tool-less, unobtrusive means of mounting the sensor on a conveyor. Ball-and-swivel and half-clamp mounting brackets are also available to facilitate precise positioning of Econo-Vue sensors.  The Econo-Vue series also delivers housing versatility with both straight optic and right angle optic models. Straight optics are best suited when mounting the sensor through conveyor side-walls, and right-angle optics are best suited when mounting the sensor on top of conveyor side-walls. With some competitive types, the only way to get right angle sensing is by using an additional deflector accessory which adds cost and installation time.“In addition to having a cost effective price tag, Econo-Vue sensors consume up to 50% less current than other M18 cylindrical photoelectric sensors. This does not just mean the series is more environmentally friendly: it also means it costs less to operate each sensor. Lower power consumption means it is possible to power more sensors per power supply, potentially cutting in half the number of power supplies required in a given application,” says Allison.Econo-Vue sensors are available in tamper-proof models that eliminate external adjustments and operate at maximum signal strength. This eliminates erroneous adjustments after the sensor is commissioned.  Additionally, the status LED functionality is standardized meaning that the sensor’s status LEDs do not just indicate it is powered and sees a target, but it also indicates if the signal strength is lower than it should be. Status LEDs are also highly visible and placed in dual positions - 180 degrees apart on the housing - for increased visibility.The Econo-Vue series is ideally suited for use in material handling applications, primarily  as a conveyor sensor for the reliable detection of cartons, totes, or cases either through the side-wall of a conveyor or over the top of a conveyor.  They are also well suited for use in packaging applications including, among others, web break detection and carton magazine low-level detection.  The Econo-Vue is a very reliable general purpose sensors that can also be used in a number of other markets, including printing/paper and automotive.HOUSING MATERIAL Polycarbonate
