Are there any precautions or recommended products when using multiple photo reflector products side by side ?

Optoelectronic Devices

 When use multiple photo reflector products side by side, it depends on the distance between the products, but if the distance between products is 20 mm or less (approximate), we recommend using Periphery shading walls products in order to reduce the interference between products.

Depending on the presence or absence of a periphery shielding wall, LED light emission and sensor sensitivity directivity vary greatly. Please consider using a product with a periphery shading wall and narrow directivity.
