Turck has introduced weld nut sensor for automotive metal detection. Metal detection in the automotive industry requires more compact sensor technology to manage constant change in metals and application variations as parts move through the line. Turck’s weld nut sensor is a solution for applications that require a reliable detection for the presence or absence of a nut welded to sheet metal on various vehicle components.

low-profile-weld-nut-sensor_turck_buTurck’s design uses magnetic inductive technology and can be simply programmed to detect the presence of a metallic nut. An optional teach pendant can be used to program the sensor to differentiate between the sheet metal material and the weld nut. When the nut is properly placed, the sensor sends a signal to the PLC, which allows the robotic welder to weld the nut to the sheet metal.

Turck’s weld nut sensor measures 61 mm, with a probe tip diameter of 4 mm to accommodate down to a 5 mm weld nut. The sensor has a titanium nitride coated probe for greater…
