What inductive proximity sensor material is best for use with machine coolants?
Answered by: Shane Jaconelli, RS components
Sensors are available in many materials, including A2 (304) stainless steel or A4 (316L) stainless steel. Generally, A2 stainless steel sensors are suitable for use with most coolants.
However, please make sure you take other factors into account before purchasing, such as aggressive cleaning agents, pressures, and temperatures. If you’re in doubt, check with the chemical supplier.
