Detect small, dark or transparent objects with precision

When you need precise measurement of object distance, our new IO-Link distance sensor is the ideal choice. Whether you want to precisely determine the location of a component, guarantee precise positioning of small parts, or reliably detect stack height, it delivers absolute accuracy.

Its fine, clearly delineated laser beam lets you detect even the smallest objects with precision. The sensor’s enhanced background suppression capability allows it to detect and measure dark objects — down to 2% reflectivity. In this method, the sensor is taught the target object, which is then discerned and detected each time with high precision. This sensor can also detect transparent objects, such as plastic film or products.

The sensor also offers a switching output that you can use as a limit switch. This switchpoint capability also provides the ability to have two outputs on the same sensor.

You can also individually set the measuring range of the sensor, thanks to the analog output curve which can be adjusted to your application. And setting the sensor is easy. Both the switching point and the analog output curve can be taught using a simple key if not using IO-Link. And if using IO-link, these features and settings can be accessed using the convenient Balluff IO-Link Device Tool USB GUI interface window.

Installation is fast using a mounting bracket or dovetail clamp, which also speeds up commissioning. This Class 1 red light laser sensor, in an IP67-rated housing, has a 30–200 mm range, though its actual focal length is 400 mm — so you can be assured of absolute accuracy when used within its stated range. And the 4–20 mA analog output now has scaling capability.
