Note:An emission stop function can be added to Through-beam Models as a custom function. Ask your OMRON representative for details.
*Consult with your OMRON representative if a distance of more than 10 m is required. Models with large custom-size spots can be produced. These make optical axis adjustment easier and allow the beam to be received more stably by the Receiver even if vibration is present.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
