LED Sensors are safer than lasers
The LH-50 Series of high precision measurement sensors is an LED based system that offers the same measurement performance as a Class 1 or 2 laser based system .This eliminates any concerns about optical safety, which is one of the issues normally associated with laser based systems. Applications vary considerably for such flexible units, but can be typically used where accurate measurement is required in an industrial environment. For example, level difference between two surfaces and thickness measurement of a product.
