Turck adds low-profile model to its weld nut sensor offering

May 6, 2017 – Turck describes its low-profile weld nut sensor as a compact solution for applications that require a reliable detection for the presence or absence of a nut welded to sheet metal on various vehicle components.

Like the other sensors in this family, the device boasts a low-profile design that uses magnetic inductive technology and can be 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, explains Turck. The 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 that promises greater strength and protection in harsh applications. The cable version includes a TPE-style jacket with a molded M12 connector for flexible mounting possibilities, and a four-way LED.
