Description
Technical field
The utility model relates to sensor technical field, relates in particular to a kind of novel inductive proximity transducer.
Background technology
The inductance type proximity transducer is a kind of position transducer of non-cpntact measurement; Be to utilize eddy current effect to control the starting of oscillation and the failure of oscillation two states of high frequency oscillator; Realization is to the detection of position quantity; And convert it into the output of electric switch amount, thereby realize the control of load or the conversion and the transmission of signal.It has reliable operation, stable performance, repetitive positioning accuracy high, do not have mechanical wearing and tearing, long service life, no-spark, noiselessness, outstanding advantage such as antijamming capability is strong, environmental suitability is strong.It is circular mostly the shape of existing inductance type proximity transducer is, under some certain environmental conditions, aspect installing and using, needs specific shape, and this is just for installing and using and brought very big inconvenience.
Summary of the invention
Therefore, to above-mentioned problem, the utility model proposes a kind of simple in structure, is shaped to squarely, and stability is high, can better meet the novel inductive proximity transducer of customer demand.
For solving this technical matters; The utility model is taked following scheme: a kind of novel inductive proximity transducer; Comprise the square shell magnetic core inner, the pilot lamp that is surrounded on the coil on the magnetic core, the circuit board that is connected with magnetic core electric wire and is connected with circuit board with being arranged at square shell; Said coil and the electronic component electric capacity on the circuit board that is surrounded on the magnetic core is formed a LC oscillator, and said square shell inside is provided with reinforcement, and said circuit board is fixedly arranged on the reinforcement.
Further, the circuit of said circuit board is made up of LC oscillator, trigger circuit and output circuit series connection, and the output terminal of said output circuit connects external unit.
Further, said square shell is a plastic casing.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: be shaped to square so that better meet customer demand through setting; Circuit board is fixed on the square shell, make the connecting line of circuit board and power supply conveniently weld, and easy damaged is not perhaps pulled apart; Simple and compact for structure, make things convenient for production and assembly and use, enhance productivity; And make the stable higher of the utility model product, accurate positioning, long service life.
