Safety Explosion-proof Proximity Switch
Namur sensor, also called safety explosion proof proximity switch, is made according to NAMUR and DIN 1923, measured and designed as per chemical industry standard.
With low-voltage power supply,micro-current output,small volume and other advantages.Namur sensors can be applied for special places with requirements of explosion proof.

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.
1. The applications of sensor ?
A: Punch, Machine tool, Automatic controller, Automatic water device, Semi automatic industrial control equipment
2. How to confirm the sensors model ?
A: The buyer need to provide the below information : Voltage NPN/PNP NO/NC/NO+NC Detected object Detected distance
3.The characteristic of Safety Explosion-proof type?
A: (1)Detect metal
(2)Low current and low voltage , the range of voltage 5V~12V
► DC switch should adopt insulation transformer and ensure stable voltage mains corrugation.
► 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.
► Set the switch use distance within the rated distance to avoid the effects from temperature and voltage.
► Wiring while power-on is strictly prohibited, connecting the wires strictly according to the wiring diagram and output return elmentary diagram.
► If there areany special requirements to the switch like water proof, oil proof, acid proof, base proof, high temperature proof of 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.
