Cutting oil is a mainstay of many industries, and yet its presence can lead to the premature malfunction of essential components like proximity sensors. According to an internal Omron study completed in June 2016, approximately 30% of component failures are caused by cutting oil ingress. The traditional system for measuring the ruggedness of components only considers the impact of water and dust particles and fails to take into account the need for oil resistance as well. A new rating option – known as IP67G – is starting to gain traction as a way to document resistance to cutting oil and related substances.

This white paper will examine the impact of cutting oil ingress on components and present the benefits of investing in components made from oil-resistant materials.
