Define the safety function before selecting a safety product
An emergency stop, guard switch, light curtain or safety PLC alone does not make a machine safe. Systematically assess hazards, access, stopping behavior and the required risk reduction.
Qualified people must verify the applicable standards and performance requirements for the machine type and market.
Application note
This article provides general technical information. For product selection and safety-critical applications, the exact model, manufacturer documentation and actual operating conditions should be verified separately.
