The utility model has the advantages of that: 1. the utility model can be perfectly used in highly precise automatic assembly line equipment with simple structure, small size and low price; 2. the utility model has a favorable performance, which can continuously operate 3.5 million times under the 24V DC voltage, 20 mA DC current and a frequency of 1600times/minute. The response time of the on/off unit is shorter than 10ms. The DC current range is from 5 to 20mA; the utility model has an easy operation with low energy consumption, the signal output can be directly displayed by the LED, the equipment failure rate is tremendously lowered with a long life-span.
Description
Technical field
The utility model relates to electric switch, and is particularly a kind of as automatically control, spacing magnetic sensor.
Background technology
Magnetic sensor is widely used in industrial department and does spacing and the automatic control switch use.At present, domestic production and sale magnetic sensor volume ratio are bigger, and the scope of application has certain limitation.Though external magnetic sensor volume is less relatively, costs an arm and a leg.The patent No. is that the Chinese patent of CN200420026861 discloses a kind of magnetic induction near switch, comprise housing and be installed in housing interior tongue tube, wiring board, be connected with on the wiring board and be drawn out to the outer lead of housing, circuit on the wiring board is made up of tongue tube, current-limiting resistance, light-emitting diode and the backward diode opposite with the light-emitting diode direction, connect with current-limiting resistance after light-emitting diode and the backward diode parallel connection, and then in parallel with tongue tube, the position corresponding with light-emitting diode has the through hole that light-emitting diode is exposed on the housing.Its weak point is that structure is still complicated, the manufacturing cost height.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, volume is little, price is low, performance is excellent magnetic sensor is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of magnetic sensor, comprise housing and be installed in housing interior tongue tube, wiring board, be connected with on the wiring board and be drawn out to the outer lead of housing, it is characterized in that: the circuit on the wiring board is made up of tongue tube, current-limiting resistance, light-emitting diode, and current-limiting resistance is connected with light-emitting diode, tongue tube.
For optimizing technique scheme, the measure that the utility model is taked also comprises:
Described current-limiting resistance, light-emitting diode are paster current-limiting resistance and patch light-emitting diode;
Position corresponding with light-emitting diode on the described housing has the hole;
On the described housing fixing threaded hole is arranged.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:
1, simple in structure, volume is little, price is low: its volume is 4 * 18mm, subminiature volume can be widely used it in the slot of cylinder surface, and the volume of cylinder also can further dwindle, and can be applied to better in the high-precision automatic assembly line equipment;
2, performance is excellent: at direct voltage 24V, and direct current 20mA, but and continuous action 3,500,000 times during by 1600 times/minute frequency.If reduce its operating frequency, action frequency can also corresponding increase.ON, OFF response time are below 10ms.Scope 5～the 20mA of direct current.Energy consumption is low, and easy to use, and the output of signal directly shows that by the LED luminous tube long service life greatly reduces equipment failure rate.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the circuit diagram of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
See figures.1.and.2, the utility model comprises housing 2 and the tongue tube 3, the wiring board 6 that are installed in the housing 2, is connected with the lead 1 that is drawn out to outside the housing 2 on the wiring board 6.Circuit on the wiring board 6 is made up of tongue tube 3, paster current-limiting resistance 4, patch light-emitting diode 5, and paster current-limiting resistance 4 is connected with patch light-emitting diode 5, tongue tube 3.Position corresponding with patch light-emitting diode 5 on the housing 2 has hole 8.Fixing threaded hole 7 is arranged on the housing 2.
Its course of work is: the direct current of anodal termination 24v, and by load 9 flow through twin cable line 1, paster current-limiting resistance 4, patch light-emitting diode 5, tongue tube 3.For example, in the time of in being installed in pneumatic means, the magnet ring of cylinder piston rod is by tongue tube 3 induction back the utility model circuit turn-ons, and patch light-emitting diode 5 is luminous, and signal is exported from negative pole end, the cylinder stop motion.After the magnet ring of cylinder piston rod left the induction range of tongue tube 3, tongue tube 3 disconnected, and patch light-emitting diode 5 is not luminous, the output of negative pole end no signal, and cylinder resets.The utility model can be fixed in the slot of cylinder surface by the fixing threaded hole on the housing 27, installation direction can be laterally or is vertical.
