Minsk Research Institute of Radiomaterials of the National Academy of Sciences of Belarus offers consumers inductive proximity switches VIB-M12V4-PO-K3-2-51/38-L and VIB-M18V5-PO-K3-2-59/45-L under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

OJSC "Minsk Research Institute of Radiomaterials" of the National Academy of Sciences of Belarus manufactures inductive proximity switches VIB-M12V4-PO-K3-2-51/38-L and VIB-M18V5-PO-K3-2-59/45-L, designed for non-contact control of the position of moving parts of mechanisms at certain points of the trajectory and switching of electrical control and signaling circuits.

The principle of operation of the switch is based on the interaction of the electromagnetic field created by the sensitive element of the switch (the inductor of the LC generator) with an external metal object of influence. When an object of influence is introduced into the electromagnetic field zone of the coil, generation stops, the demodulated voltage drops and the threshold device is triggered, which leads to a change in the state of the switching element (output key).

The inductive proximity switch has the following design features:
* withstands vibration loads with a frequency of 50 Hz for 8 hours with a maximum acceleration of 5 g according to GOST 3940-2004;
* withstands impact loads in the amount of 10,000 impacts with a maximum acceleration of 10 g according to GOST 3940-2004.

The switches are characterized by:
* high reliability;
* unambiguous dependence of the output value on the input;
* stability of characteristics over time;
* small size and weight;
* the absence of a reverse effect on the object;
* tightness, IP 67.
