Multiple light beam safety devices are electro-sensitive protective devices comprised of a sender and a receiver unit or a sender/receiver unit on the active side and one or more deflector mirrors on the passive side. If one or more light beams are interrupted, the multiple light beam safety device provides a shutdown signal that is suitable for interrupting the dangerous state on a machine or system.
