Proven distance measurement on reflector for large sensing ranges

DML40 sensors are designed for very large sensing ranges. Time-of-flight measurement enables measuring ranges of up to 1,200 m on one reflector, thus offering access to many applications in which large sensing ranges are the order of the day. A rugged design along with numerous configuration options via a software program underlines the versatility of this product family.
