In scenarios involving automated equipment and industrial safety protection, when multiple sets of safety light curtains are installed adjacent to each other, there is a tendency for signal interference to occur, resulting in the light curtains being unable to effectively perform their protective functions. To address this common issue, it can be effectively resolved by adjusting the installation layout. The specific methods are as follows:

Place the transmitters at different positions in front and behind to install the transmitters of the adjacent two sets of light curtains at different positions to avoid direct light path overlap and cut off the interference path spatially.

Install the transmitters back-to-back to install the transmitters of the two sets of light curtains in opposite directions, allowing the emitted light rays not to directly intersect, completely avoiding signal crosstalk.

Install the transmitters in the same direction and add a partition in the middle. The transmitters of the two sets of light curtains maintain the same direction, and add a shading partition in the middle to block the mutual scattering and interference of the light rays.

Install the transmitters in a relative position and arrange them with the upper and lower positions offset to place the transmitters relative to each other, but with the upper and lower positions offset, so that the light paths are not aligned, avoiding false judgment by the receiving end and causing interference. 

The above four installation and adjustment methods can effectively solve the problem of mutual interference among multiple safety curtains caused by overlapping light sources, ensuring the stable and reliable safety protection of the equipment.
