Banner Engineering now offers new features for its EZ-SCREEN non-contact, point-of-operation machine guarding safety light screen system, making it arguably the most feature-rich and flexible system available on the market today. Key additions include fixed blanking to accommodate materials and tooling inflow with no reduction of operator safety, a cascading option for connection up to four EZ-SCREEN pairs and multiple ac interfaces. All EZ-SCREEN products offer diverse-redundant and self-checking design (Category 4) at prices that won't destroy your budget.
