Reed Sensor

Reed sensor also called magnetic switch, reed sensor is application for position determination of pneumatic and / or hydraulic cylinder and piston pump. It also can be used as limit switch .When the magnetic object approaches, the reed closes and sends out switch signal through magnification. Compared with inductive sensor ,it has the following strong points: can be installed in metal closely and side by side and detect through metal object.Its detection distance subjects to the intensity of magnetic field of detected object.Reed sensor is not applicable in the occasion of severe vibration.

Features:

1 . Diversified exterior structures
2 . Good performance of anti-interference.
3 . Many output forms
4 . Dust proof,vibration proof,water proof and oil proof.
5 . With short-circuit protection and inverted connecting protection.

Cautions:

1 . DC switch should adopt insulation transformer and ensure stable voltage mains corrugation.

2 . If any electric power line or dynamic line passes through the surrounding of switch lead-wire,in order to precent the switch from damage or error action,cover the metal bushing on the switch lead-wire and ground it to the earth.

3 . Set the switch use distance within the rated distance to avoid the effects from temperature and voltage.

4 . Wiring while power-on is strictly prohibited,connecting the wires strictly according to the wiring diagram and output return elmentary diagram.

5 . If there areany special requirements to the switch like water proof,oil proof,acid proof,base proof,high temperature proof with any other specifications,the users are required togive clear indication when placing an order.We can produce according to the requirements of the user.

Working priciple Inductive proximity switch

Inductive proximity switch is composed of three parts:oscillator,switch circuit and magnified output circuit.The oscillator will generate an alternating electric field.When hemetal object approaches this electric field and reaches the induction distance, whirlpool will generate in metal object, resulting in attenuation of vibrati on and then stop.The changeof vibration and stop of oscillator is treated by begid stage magnified circuit and convertedto switching sign,triggering driving con-contact detection.
Current consumption of inductive proximity switch decreases proportional to the metal object distance.
