Many manufacturers have learned the hard way, discovering that the safety measure they originally implemented are no longer truly protecting their team. In these situations, high-coded door switches with OSSD (output signal switching device) outputs are essential for upholding safety best practices and protecting workers.

This white paper discusses the benefits of Type 4 high-coded safety door switch and best practices for their implementation.

Topics include:

  • Understanding the different coding levels and type categories
  • Alternatives to Type 4 high-coded door switches
  • The purpose of the ISO 14119 standard
  • Understanding fault masking and how to prevent it
