Sensors from Contrinex’s Weld-Immune range with ACTIVSTONE™ coating offer the highest level of weld spatter resistance. A high-performance ceramic material forms a durable, non-stick coating on all external surfaces of the sensor, including the fixing nuts. By preventing weld spatter accumulation, this coating makes slag removal much easier and reduces maintenance costs.
All Contrinex Weld-Immune sensors combine optimum detection sensitivity with immunity to magnetic interference, in particular from medium-frequency weld fields (current up to 15 kA). They are ideal for the hostile working environments found in automotive factories and other industrial welding plants.
Sensors from the Full Inox family are recommended for long service life in the most demanding welding environments. A sealed, one-piece housing in V2A/AISI 303 stainless steel provides excellent chemical and mechanical resistance to shocks, vibration and abrasion. Best-in-class sensing ranges of up to 16 mm eliminate the risk of collision damage – a frequent occurrence when operating in close proximity to moving machine parts. In addition, sensors are unaffected by weld spatter, metal dust or chips and offer long operating distances with factor 1 on steel and aluminum.
