Standard inductive proximity sensors are not suitable in hot metal stamping, glass manufacturing, steel and aluminum manufacturing, steel forging, steam curing, or other high-temperature environments.
Balluff offers solutions with a family of high-temperature proximity sensors rated to provide reliable, non-contact object detection in ambient temperatures up to 230 °C / 446 °F.
This heat-fighting sensor lineup is better equipped to combat heat-related malfunctioning and failure than standard proxes, where temperature ratings typically do not exceed 70 °C / 158 °F.
In order to withstand extreme temperatures, the face of each sensor is composed of a heat-resistant LCP (liquid crystal polymer) material. The head of the sensor contains only the non-electronic passive components of the device, which are less susceptible to heat.
The electronic amplifier (rated to 70 °C / 158 °F) is molded into the M12 connector at the end of the cable and does not require separate mounting. The cable length of 5 m / 16 ft. allows placement of the amplifier well away from the process, outside the high temperature zone. The cable jacket and insulation, made from heat-resistant PTFE, is specified to withstand the full-rated temperature of the sensor head.
Available in M18, and M30 tubular housings with integrated 5 m amplifier-connector cable, and in block styles with detachable 10 m / 33 ft. amplifier-connector cable (order separately).
