Rugged proximity sensors

August 2002 Sensors & Transducers

Turck is now offering its Stoneface inductive proximity sensors, robust devices offering durability similar to stainless steel face sensors, at standard sensor prices. The sensors' rugged 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. Stoneface sensors are available with unplated brass, stainless steel or Teflon-coated barrels. The new sensors are suitable for applications in the automotive assembly, body and power train industries where abrasion is a factor.

For mounting flexibility, a eurofast connector and mounting bracket allow the sensor to be mounted straight or at a right angle to the cord. An optional bracket is also available for mounting Stoneface sensors at a 0 to 20° rotational angle in applications requiring a precise sensor angle. Cubical models feature a fully-rotatable sensing head that allows them to be mounted in any of five directions, straight up, North, South, East or West for sensing flexibility.

Stoneface sensors are available in Uprox and ferrite-core styles. Both styles are available in embeddable and nonembeddable models and feature short circuit, overload, wire-break and reverse polarity protection.

Designed with a nonferrite core, the Uprox models are unaffected by the strong electromagnetic AC or DC fields found in resistance welding operations. Uprox models are capable of sensing all types of metal at the same range, including mild steel, stainless steel, copper, brass and aluminium. This feature allows users to purchase and inventory fewer sensors and eliminates downtime for adjustments when target materials change. Uprox models also feature a patented 3-coil circuit design that provides up to 350% more range than standard proximity sensors. The added range provides superior mounting flexibility.

The sensors are available in 12, 18 and 30 mm barrel style bodies; and Q-style cubical bodies measuring 25 or 40 mm2. They have a repeatability œ2% of rated operating distance, and are available with NPN (sinking) or PNP (sourcing) outputs. They are available in 20-250 V a.c. or 10-30 V d.c. models.

Rugged and dependable Stoneface sensors withstand harsh sensing environments and meet IP67 seal rating standards. A wide operating temperature range -30 to +80°C) enables the Uprox models to perform better in both high and low temperature applications. They can be mated with a tough 5 m minifast cordset.
