Proximity Sensors ignore ferrous materials.

Press Release Summary:



NF Series non-ferrous barrel style proximity sensors are used in applications where non-ferrous targets need to be sensed and ferrous material needs to be ignored. Stoneface(TM) front face is made of thermoset plastic developed for resistance to weld slag, scratching, pitting and abrasion. Sensors are available in 12 mm, 18 mm and 30 mm dia bodies with NPN (sinking) or PNP (sourcing) normally open outputs, and 10 to 30 Vdc operation.

Rugged, New Non-Ferrous Proximity Sensors Ignore All Ferrous Materials


Minneapolis, MN-October 31, 2001-TURCK Inc. has announced NF-Series non-ferrous barrel style proximity sensors. These unique
devices are used in applications where a non-ferrous target needs to be sensed, but a ferrous material is also present and needs to be ignored. These new NF sensors will reliably detect aluminum, brass, copper and other non-ferrous metals, but will not detect cold rolled steel or stainless steel. Applications include automotive power train where an aluminum engine block needs to be detected but also present are ferrous taps or bolts that need to be ignored. Other applications include food and beverage, conveying and material handling.

New NF-Series sensors are extremely rugged featuring a one-piece stainless steel barrel for superior strength. The sensors' rugged Stoneface(TM) front face is made of an advanced thermoset
plastic specifically developed for improved resistance to weld slag, scratching, pitting and abrasion in MIG, TIG, and resistance welding applications. It offers durability similar to stainless steel face sensors, at standard sensor prices. List prices begin at $86.00.

These sensors are available in 12 mm, 18 mm and 30 mm (0.48", 0.72" and 1.2") diameter barrel style bodies. They have a repeatability of ±2% of rated operating distance, and are
available with NPN (sinking) or PNP (sourcing) normally-open outputs, 10-30 VDC operation.
