SMD Terminal Blocks BJB Electric SMD Terminal Blocks enable easy implementation of individual luminaire designs. Designed for use with both solid and flexible conductors, these surface-mounted Terminal Blocks are made from a glass-fibre-filled polyphthalamide (PPA-GF)-based compound, offering improved durability and performance compared to traditional engineering thermoplastics. The SMD Terminal Blocks are also ADS-compatible and can be wired robotically.
