Safety explosion-proof switch

Safety explosion-proof switch are based on German technology standard NAMUR NIN19234 technical file date production., NAMUR standard for the chemical industry, metrology and standards for design. NAMUR sensors mainly composed of inductor oscillator and demodulator, can detect metal objects and sensor displacement into a current signal changes. When the metal object close to the surface when the security sensors should, NAMUR initiators (no internal amp), to change the current consumption, these sensors with the appropriate amplifier can be connected with supporting the use of low-voltage power supply as designed, micro-current output, it can be proof required in a dangerous place.
