This has various merits, which gives versatility for its application in different industries such as optical proximity sensor. Firstly, its non-contact detection means that the sensor is pretty long-lasting and has a more extended life span. Secondly, it is important to provide correct and reliable readings in order not to spoil automated processes efficiency or quality. And Thirdly it is small and slim, making it easy to nest the relay wherever you want in a tight place or as part of a larger system. And since the sensor has a quick response time, incidents are detected fast and efficient – which brings efficiency to operations. Its low power consumption also makes it suitable for long term use, at an affordable rate as well.
