The safety device MSD is a single beam barrier with emission of visible laser which, within a more general control system, contributes to the protection of the operator in the use of machinery including dangerous mobile parts controlled by electric or electro-mechanical devices.

Main task of MSD is to detect, within the limits defined by the device detection capability, the intrusion of any opaque physical elements inside the area defined as “detection area”,  In any case of danger, the power supply of the machine control devices and/or to activate functions which stop the motion of the dangerous parts.

Main task of MSD is to detect, within the limits defined by the device detection capability, the intrusion of any opaque physical elements inside the area defined as “detection area”, which is defined by the point of the emission of the laser beam generated by the transmitter up to the point of reception of the receiver of this device. The tool has been designed to disconnect, in case of danger, the power supply of the machine control devices and/or to activate functions which stop the motion of the dangerous parts.

These functions have been realized providing in output, via the contacts of the two OSSD’s, two different electrical ON/OFF signals: the status ON corresponds to the condition when the transmitter beam reaches collimated the receiver, while the status OFF corresponds to the lack of collimation between the two components (due, for instance, to the intrusion of an element into the detection area) or to the lack of power supply to MSD.

The OSSD outputs, properly inserted in the electric circuit for the command of the machinery dangerous parts, enable the control of the machinery movement (in status ON), or, vice versa, the capacity to inhibit or stop it (in status OFF).

Protected area

The transmitter generates the emission of a modulated laser beam with intensity lower than 1 mW which, if detected by the receiver, creates a detection area and causes the receiver activates the switch to status ON of the two OSSD’s present in it.
