Due to their high resolution and fast response time, frame light barriers are often used when parts that are ejected from a machine need to be detected. But these kinds of solutions have the distinct disadvantage that their detection range is fixed. This means that the ejected parts can only be captured inside the frame.

The new light curtains of the OY41 series are significantly more flexible in this regard. While these devices also require a certain field height and alignment between the transmitter and receiver rails, the range is variable and can extend up to 8 m depending on the version. The very short response times ensure that even very fast parts or objects are safely detected. And lastly, the new light curtains can be connected to all common control units via the exclusive-OR push-pull switching output.

If you need to determine the position or dimension of an object, the OY41 with analog output is recommended. The light curtains feature both a voltage and a current output. Four different measurement modes can be configured via two DIP switches. The range is between 300 and 4000 mm, whereby the highest resolution is achieved in the middle of this range.

The M3 threads on the back of the light curtains facilitate mechanical assembly. In addition, an angle set is offered under article number AO000550.
