The working principle of namur proximity switch - Switching power supply -

Namur proximity switch in domestic development already has 20 years, mature technology, quality good, do manual work is delicate and durable, the price is reasonable, the brand has a higher visibility. Performance is very good, more convenient, because the festo proximity switch is a kind of no direct contact with the moving parts of machinery and can operate on the location of the switch.

about NAMURNAMUR signal to the nature of the world's most widely used safety standards of the digital quantity input and frequency of the input signal. The earliest for the German standard ( DIN19234) 。 After becoming the European standard ( EN50227 DINEN60947 - 5 - 6) 。 NAMUR signal for the passive 2 wire, nominal 8 VDC power supply, 1 3 ma ma and switch signal.

NAMUR type sensor are intrinsically safe explosion-proof instrument, usually used with isolation type safety barrier. By isolation gate provides 8 VDC power supply for sensors, and test the current signal. Usually for 1 or less. 2 ma and 2 or higher. 1 ma, gelizha converts this switch signal to relay signals, active or passive 0 24 v transistor switch signal.

namur on principle of proximity switch namur proximity switch is not directly contact with mechanical moving parts to the location of the switch operation, when the surface distance closer to the induction switch, do not need mechanical contact, also do not need any pressure can make the switch action, so as to drive a direct current or to a computer ( PLC controller) The device provides control instruction. Proximity switch is a switch type sensor ( The non-contact switch) Features, it has a travel switch, at the same time also has the performance of the sensor performance is stable and reliable frequency response is fast, long service life and strong anti-jamming capability, etc. , and has the characteristics of waterproof, anti-corrosion, shock.

1, NAMUR signal to the world, the most widely used on the nature of the security of the digital quantity input and frequency of the input and standard signal. The earliest for the German standard ( DIN19234) 。 After becoming the European standard ( EN50227 DINEN60947 - 5 - 6) 。 NAMUR signal for the passive 2 line

nominal 8 VDC power supply, 1 3 ma ma and switch signal. 2, NAMUR type sensor are intrinsically safe explosion-proof instrument generally and isolation type safety barrier with

use. By isolation gate provides 8 VDC power supply for sensors, and test the current signal. Usually for 1 or less. 2 ma and 2 or higher. 1 ma, gelizha converts this switch signal to relay signals, active or passive 0 24 v transistor switch signal.

namur this Ann a proximity switch about 32 yuan. Have a wide voltage range, high repeat positioning accuracy, fast frequency response, anti-interference performance is good, easy installation and debugging, the advantages of long service life.
