The New Fork Sensor in wenglor's InoxSens Hygienic Design

(PresseBox) ( Tettnang, )
Production sequences in the pharmaceuticals and food industries are subject to extremely demanding hygiene standards. Thanks to corrosion-free stainless steel, FDA-conformity and Ecolab certification, wenglor’s new P1HJ00X laser fork sensor in InoxSens hygienic design provides maximized protection when detecting objects. Thanks to the collimated laser beam, extremely fine quality inspection in the micron range is strictly routine – with fork widths of up to 220 mm.

Objects with sizes down to 40 µm can be reliably detected by the new fork sensor. “That’s thinner than a human hair”, explains wenglor product manager Flora Klein. “Thanks to the collimated laser beam, objects can be perfectly detected within the entire fork width – not only within certain ranges as is the case with many comparable products.” There are a total of six models of the P1HJ00X InoxSens light barrier with fork widths of 50, 120 and 220 mm, each with an optic cover made of glass or plastic as desired – custom tailored for the requirements of any industry sector.

The fork sensor with gap-free design is resistant to cleaning agents in hygienically sensitive industrial environments (Ecolab certified) and also complies with the highly demanding material specifications stipulated by the Food and Drug Administration (FDA). Liquids run off of their own accord thanks to the special hygienic design. Together with the hermetically sealed housing, captive components provide for high levels of protection up to IP69K. Beyond this, the light barrier can be easily and conveniently adjusted directly at the sensor by means of an intuitive teach-in button. Suitable accessories in hygienic design with watertight cable gland round out the system.

The packaging, paper and consumer goods sectors benefit from this product in addition to the pharmaceuticals and food industries, because the fork sensor is used in particular wherever numerous objects traveling at high speeds have to be reliably detected – using a procedure which is reproducible millions of times over.
And thus the fork sensor’s range of applications includes the detection of bottles, cannulae and syringes, as well as the inspection of gaps, holes, slots and notches. Objects to be detected can even consist of transparent materials such as glass or plastic.
