🛑 Safety Light Curtain: Stopping Time and Minimum Safe Distance (2D)

Top view of a conveyor workcell guarded by a light curtain. Set the approach speed, beam resolution, curtain response, PLC scan time, relay drop-out, belt speed and braking, and see where the stopping time goes and how far from the hazard the curtain must stand. A time-stepped hand and belt simulation is checked against the minimum-distance formula, with four in-page numerical checks.
