Increased Safety Unicode 2 Series polyamide control stations and switches, manufactured by Appleton ATX, are ideal for use in hazardous areas and washdown areas. A variety of push buttons, selector switches, illuminated push buttons, control and load break switches and LED pilot lights are available for use in conjunction with contactors or magnetic starters for the remote control of motors. The ATEX certified control stations provide safe circuit control and/or selection in potentially explosive atmospheres. Pilot lights are available to provide visual assurance that an electrical function is being performed at a remote or local location. These polyamide control stations are ideal for the control of equipment at power, chemical and petrochemical plants, petroleum refineries, re-verse osmosis plants, pulp and paper processing plants and various other industrial applications.
Appleton Unicode 2 Series uses the Ex de method of protection which eliminates the need for external seals. Unicode 2 Series features a choice of DIN rail mounted high performance contact block suitable for low intensity (less than 5 mA). TS35 rail mounted components are held securely in place during operation and easily removed for service.
