Conductive ESD plastic storage bins, QUS220CO measures 7-3/8" x 4-1/8" x 3" and protects your electronic components from typical electromagnetic interference (EMI), electrostatic or induced fields. The conductive material on polypropylene stack and hang bins provides a barrier these fields cannot penetrate and prevents the build-up of electrostatic charge. ESD storage bins are permanently conductive and are unaffected by washing with normal cleaners. Molded from a carbon filled copolymer polypropylene material with a electrostatic decay rate at less than 0.1 second that meets military specification Mil-B-81075B. Its surface resistivity is less than 10⁵ Ohms-per square. Easy access to stored items with hopper front storage bins. Bins can hang from Conductive ESD louvered panels, bench racks and rails. Be sure all units are properly grounded according to your use. Color is Black.
