摘要:
The invention relates to a light grid unit (22) for forming a transmitter and/or a receiver of a light grid securing unit (20) for an automatically driven gate that is provided with guide rails (12). In order to create a light grid unit that can be easily mounted in the exactly fitting position on the gate to be monitored, a profile housing (24) for receiving a longitudinal light grid element (26) is proposed which is designed for transmitting or receiving a series of light beams, wherein the profile housing (24) has at least one abutment region (48) (48) that is designed for the abutment of the profile housing (24) on a guide rail (12) of the gate (10) in the direction of the longitudinal extension of the guide rail (12).
