The laser beam of the EX-L291-P reflex light barrier from Panasonic Industry is characterized by highly precise beam guidance. This means that gold wires as small as 0.01mm in diameter can be detected over the entire beam width (EX-L221). With a repeat accuracy of 0.02mm, this sensor is ideally suited for positioning tasks. The alignment of transmitter and receiver is simplified by the visualization of the beam by means of a reflecting material at the light input of the receiver. The optimal position is visible at a glance and is supported by the stability indicator (green). With the IP67 protection class, this sensor can also be used in environments with heavy water or dust.
