Machine Guard Safety Distance Calculator

Calculate the ISO 13855 compliant mounting distance for electro-sensitive protective equipment (like Light Curtains or Laser Scanners) to hazard zones.

Purpose & Calculation Breakdown (India)

Purpose of this Tool: Ensure safety devices are placed far enough from moving machinery to guarantee full hazard stoppage before a human reaches the point of danger.

• Mounting Distance Equation (ISO 13855):S = (K \times T) + C
• Where parameters represent::T = T_{machine\ response} + T_{safety\ sensor\ response},\quad C = 8 \times (d - 14)
