The SIGUARD laser scanner LS4 is an optical distance sensor. The device periodically transmits light pulses within a working range of 190°. If these pulses hit an obstacle or a person, the light is reflected, received by the laser scanner and evaluated. The scanner calculates the exact coordinates of the "seen" obstacle from the light propagation time. If the obstacle/person is within the programmed zone, the scanner initiates a safe shutdown.
