The latest line of extended-temperature proximity sensors from Balluff doubles the maximum temperature rating of standard sensors. This makes them ideal to battle the heat found in many industrial automation environments including robotic weld cells, where localized temperatures increase due to radiant heat from frequent weld flashes and conducted heat from molten welded materials. Where conventional inductive proximity sensors would quickly fail, Balluff’s extended-temperature line of sensors provides reliable, non-contact object detection in ambient temperatures from 130 °C / 266 °F up to 150 °C / 302 °F.
The technology is most beneficial to the automation needs of those in industries such as hot metal stamping, steel forging, and glass manufacturing, as standard inductive proximity sensors are unsuited for high-temperature environments. Limited to 70 °C / 158 °F, standard sensors are susceptible to malfunctioning, failure, and ultimately, machine downtime.
Balluff’s sensors offer increased heat resistance thanks to the use of a liquid crystal polymer face. Both the active electronic and passive sensing components are included in the head of the unit and housed in stainless steel.
The new sensors are available in M8 tubular housings, with a 5-meter heat-resistant PTFE-jacketed cable, and block-style housings with a 5-meter silicone cable.
