Sensors add hygienic options for food and reflective packaging detection challenges

Two new sensor series created by Leuze utilise stainless steel housings for hygiene-sensitive applications, whether that is for unpackaged foods or for highly-reflective glass or PET. The 33C and 35C sensor series can cope with demanding industrial cleaning processes, and come without mounting holes in the housing.

Both series include diffuse, through-beam and retro-reflective photoelectric sensors, with special options for packaging processes. These include retro-reflective photoelectric sensors for glass and PET detection, sensors with background suppression for detecting small objects, dynamic reference sensors, and powerful through-beam photoelectric sensors for penetrating plastics films.

For the first time, the new sensors include systems with Power PinPoint LED. This light technology means the sensors can be aligned and set up quickly and easily, thanks to the LED’s bright, round and homogeneous light spot. The size, shape and homogeneity of the light spot remain constant throughout the entire working range, says Leuze. Laser or infrared devices can also be used as an alternative to Power PinPoint LED.

In harsh environments, Leuze points out, it is often necessary to protect plastics-bodied sensors with specially-manufactured and costly stainless-steel covers, in order to withstand high-pressure cleaning. None of this is needed with the 33C and 35C stainless-steel sensors, reducing complexity, cost and installation time. The devices have Protection Classes such as IP67, IP68 and IP69K as well as ECOLAB, CleanProof+ and Diversey certifications, says the company.

Both series are equipped with an IO-Link interface. This enables quick and easy configuration as well as access to diagnostic data that can be used to plan predictive maintenance.
