The PR series inductive proximity sensors feature solid sensing performance and excellent noise immunity with a specialized sensor IC developed by Autonics. Available in various sizes and sensing distances, the standard cylindrical inductive sensors can be used in diverse applications requiring non-contact detection of metallic objects. The PR series is available in DC 2-wire, DC 3-wire, AC 2-wire types.

PR18-8AO comes in a round cylindrical shape, with a sensing distance of 8mm., with sensing side diameter and housing size of M18, non-shielded (non-flush) installation, AC 2-wire type (100~240VAC). PR18-8AO from Autonics comes with the following features:

  • Improved noise resistance with dedicated IC (DC 3 wire).
  • Long life cycle and simple operations.
  • Reverse power polarity, surge, and over-current protection.
  • IP67 rated waterproof structure from IEC standards.
  • Red LED status indicator.
  • Replacer for micro switches and limit switches.
