Abstract
A laser light barrier system for measuring or checking tools or workpieces on machine tools has a support which can be fastened to the machine frame. The support has an elongate base housing and two block housings, which at a mutual longitudinal distance project transversely from the elongate base housing and one of which contains a transmitter and one a receiver. The laser beam extends at a distance from and approximately parallel to the elongate base housing. An elongate stop element which is held in position by means of a latching arrangement, extends, in the space between the laser beam and the base housing, in the longitudinal direction from one block housing to the other block housing, and wherein the elongate stop element snaps off in the event of a collision with a moving tool or workpiece and, as a result, actuates an electric switch which, by acting on the emergency stop device of the machine stops the latter.
