Abstract: A safety detector including a detection module configured for reading a control signal at the input, the detector including two supply terminals, a first control input and a first control output, a first safety output and a second safety output, and a first free terminal and a second free terminal, the detector including: a second control input connected to the first free terminal and a second control output connected to the second free terminal, and a test module configured for notably applying a first test sequence including a disabling of the first control output and a test of a start loop connected between the second control output and the first control input.

Abstract: Optical detection system having: an emitter providing a collimated light beam; a receiver receiving the collimated light beam, the receiver having: a receiver lens converging the collimated light beam along an optical axis, and a corner reflector, the corner reflector having three planar surfaces perpendicular to each other and a symmetry axis coinciding with an intersection point of the three planar surfaces and forming an equal angle with each of the planar surfaces, the corner reflector reflecting the collimated light beam about the symmetry axis. The optical axis of the receiver lens is parallel to the symmetry axis of the corner reflector.
