CONTACT TARGET SENSOR Russian patent published in 2018 - IPC F42C1/00 F42C19/12 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the field of armaments and can be used in weapons of bursting munitions. Contact sensor contains a housing with an electric line, an electrical outlet, and sensing elements. Sensor element of the sensor is made in the form of a microelectromechanical system – MEMS device. This device is provided with the ability to operate under overload. Sensor has an electronic time block. Electronic time block provides the possibility of counting the time of the overload, and the formation of a control signal in the event that the measured time exceeds a certain value. In this case, the MEMS device is arranged in such a way that the operation is provided under the effect of an overload exceeding the threshold level, The input of the MEMS device is connected to the electrical conductor of the contact sensor. Other contact is connected to the input of the electronic time block. Latter provides the possibility of counting the time of the overload action exceeding the threshold level and forming, in case of exceeding the detected time, a certain value of the control signal at the output of the unit. Output of the electronic time unit is connected to the input of the second MEMS device, and the output is connected to the output of the contact sensor. Second MEMS device is arranged in such a way that the actuation is provided by the centrifugal force generated by the rotation of the contact sensor.

EFFECT: increase the reliability of the contact sensor of the target by providing increased resistance to small-scale interference on the trajectory.
