PI-SAFE

Proximity inductive safety sensors

PI-SAFE: a complete range of sensors for
positioning detection

An extensive range of positioning sensors

Inductive Safety applications are special applications which require a non-contact and safe detection of a metal object.

Proximities safety sensors

An extensive range of positioning sensors

  • Fail-safe inductive sensor
  • Certification to EN 60947-5-3
