New Sensors Offer Superior Metal Detection Capabilities

New Uprox+ sensors from Turck are capable of precisely detecting materials such as iron steel, stainless steel, copper, aluminum and brass at substantial sensing distances without a reduction in the rated sensing distance of the sensor. The company claims that Uprox+ sensors offer unrivalled performance due to a newly patented multicoil system. This multicoil system replaces the wound coil found in conventional ferrite core inductive sensors, resulting in extraordinary sensing distances (up to 250 percent higher) and the flexibility to incorporate this technology in a variety of unique housing designs.

Uprox+ sensors also feature an integrated predamping protection function to reduce the metal free mounting area in applications. This allows traditionally flush mounted sensors to be recessed by half a turn for increased mechanical protection. Non-flush mounted sensors may be embedded in metal up to the outer edge of the thread on barrel style sensors and on all four sides of rectangular style sensors, causing only a slight reduction in sensing distance.

All Uprox+ proximity sensors adhere to the present EN50082-2 standard, yet they also exceed the strict provisions required by EN61000-4-6: an integral part of industry standards by the year 2006 and beyond. This protects against conducted interference from frequency converters, and other sources that produce a high level of EMI. Uprox+ sensors provide a product that incorporates a multitude of sensing requirements; whether for the automotive industry, machine engineering or for transport and handling applications, Uprox+ sensors are capable of replacing several conventional proximity sensors.
