Contact modules for front plate mounting
Contact modules for front plate mounting are installed on the rear face of a holder.
Contact modules with gold contacts have better protection against corrosion (e.g. in
sulfurous environments) and therefore a high contact reliability at low currents and low
operating frequencies.
For further information refer to Chapters "Holders (Page 213)" and "Mounting (Page 199)".
