DC PROXIMITY SWITCH (NAMUR) (2 WIRE VERSION) Proximon Controls Pvt. Ltd

  1. DC PROXIMITY SWITCH (NAMUR) (2 WIRE VERSION)

    INTRODUCTION:
    These are analogue output switches called 'NAMUR' output switches. These are 2 wire DC switches consisting only the sensor part of the total circuit. Due to their low current and voltage, these switches are most suitable in explosive or hazardous areas, when used with switching amplifier confirming to DIN 19234. The Low impedence of the switch is virtually immune to interface pick-up on the lead connecting to its amplifier. The switching can also be obtained through interface circuit or custom microprocessor besides switching amplifier. Besides its application in the hazardous areas, these can be used in normal environment where in space is the criteria. In such cases the amplifier unit can be kept in control panel and signals can be used led to it through a long cable.
