Nass magnet can deliver magnetic coils in several variations of electrical connections encapsulated in either Thermoset or Thermoplast material. The DC models can be operated with either batteries or other voltage sources with a ripple tolerance of 5%-45%. The AC models are suitable for both 50 Hz and 60 Hz. Other variations can be configured by combining parts from the modular system. For 2/2-way functions, higher pressure and nominal width values can be achieved.
