Is there any difference between an A2 and A4 stainless steel inductive proximity sensor?
Answered by: Shane Jaconelli, RS components
Sensors are available in many materials, including A2 (304) stainless steel or A4 (316L) stainless steel. Both can be found in the food and catering industries. However, A4 stainless steel is also marine- and chemical-resistant, which makes it ideal for demanding industries such as marine, food, beverage or pharmaceuticals.
