All OMRON sensors are designed and tested to withstand vibration and mechanical shocks. The high grade stainless steel SUS 316L and the housing design of the E3ZM without protruding optics or adjusters, provides enhanced protection against mechanical damage. This not only ensures long sensor lifetime but significantly reduces the risk that cut-off or broken sensor parts are processed together with the food.

The IP69k test according to DIN 40 050 part 9 is intended to simulate high pressure / steam cleaning. During the test 14-16 l/min water at 80ºC is sprayed onto the sensor from different angles with 8000-10000 kPa. The sensor may not suffer any damaging effects from high pressure water in appearance and functionality.

The detergent resistant sensors are tested on alkaline and acid based detergents commonly used in the food industry. In comparison to conventional metal or plastic housing sensors, longer sensor lifetimes of 20 times or more can be achieved.

The housing has been designed with the usage in hygienic environments in mind. In order to reduce areas where bacteria can grow, the sensors provide a smooth surface, rounded edges and high grade SUS 316L stainless steel or detergent resistant plastic material.
