Industrial automation regularly requires object detection in high-temperature settings, but increased heat can lead to rapid failure of conventional inductive proximity sensors.
Balluff alleviates these concerns with a family of extended-temperature proximity sensors offering reliable, non-contact object detection in ambient temperatures from 130 °C / 266 °F to 150 °C / 302 °F — more than double the rating of standard sensors that are typically limited to maximum temperatures of 70 °C / 158 °F.
With all electronic components fully integrated inside the sensor's housing, installation is simplified compared to remote-amplifier alternatives. All materials used in construction, from the sensing face to the conductor insulation and cable jacket, have been selected to continuously withstand the sensor's rated operating temperature.
Three of the four models offered can be flush-mounted, allowing fully embedded, protective mounting methods to be employed. This minimizes the potential for impact damage to sensors from part loading or other movement in confined areas. To address space-constrained presence-detection challenges, these sensors are available in M8 tubular and compact block styles to fit neatly into compact fixtures and tooling.
A larger 40x40 mm block style long-range sensor, while not flush-mountable, offers 25mm / 1" of sensing range to operate out of harm's way. This model is available with a detachable, temperature-rated M12 cordset (order separately).
