Radix sensors manufactures ac as well as dc inductive proximity switches. Ac switches are available in the sizes m12, m18 and above. Pnp and npn dc switches are available in sizes m8, m12, ml8 and above. All dc switches are fully protected for short-circuit, overload and reverse polarity. Each switch is tested for all-important parameters. Ac switches work in the range of 90-250 v ac, while dc switches work with l0-30 v dc. Namur proximity switches are also available.
