Inductive high temperature sensors

Inductive high temperature sensors

Withstand extreme heat in multiple environments

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).
