The equipment comprises the body and a cover with a slot, a hermetic contact and a constant magnet, introduced a protective diode-beam waveguide, a resistor and a holder where inside the nonmagnetic body in its upper part parallel to its longitudinal axis a hermetic contact with opportunity to interact with the constant magnet is fixed, the output beam waveguide wires are fixed in the same upper part, its protective diode and a resistor, inside the nonmagnetic cover, bottom in all four angles are made buildups with opportunity to form a space for location of moving constant magnet between the nonmagnetic body and covers where atop a hole for light part output of the waveguide and a slot for transference of the holder is made and fixed on the constant magnet with opportunity to transfer to parallel longitudinal axis of the cover of the last.
