  • Proximity sensor resistant to environmental effects
    Patent number: 6617845
    Abstract: A housing for a proximity sensor is resistant to harsh environmental effects, such as scorching particles due to sputtering in a welding environment. The sensor housing is formed of a material having a high thermal conductivity, such as copper or an alloy thereof. As a result, the housing is able to rapidly dissipate heat and, in turn, mitigate weld slag build-up so as to improve the efficacy of the sensor.
