  • Page 2 1. Operating principle of an inductive proximity sensor 1: Connection 2: Housing 3: Downstream electronics 4: Capacitor 5: Pot core 6: Coil 7: Alternating electromagnetic field = active face 8: Target = electrically conductive material The coil and capacitor form an LC circuit, also known as a basic sensor. Eddy current losses in electrically conductive materials are used for a switching signal.
  • Page 3 Hysteresis Difference between the switch-on and the switch-off point. Short-circuit pro- If autosen sensors are protected against excessive current by means of tection a pulsed short-circuit protection, the short-circuit protection may cut in with incandescent lamps, electronic relays and low resistance loads.

  • Page 6 Flush and non-flush mountable In principle, “flush” and “non-flush” mounting are only of relevance in metal environments. All non-met- als such as plastics, wood and glass have no influence on the mounting. With flush mountable sensors, the sensing face of the sensor may be aligned level with the metal installation environment.

  • Page 12 - miniature sensors Inductive sensors with a short overall length and small diameters up to 3 mm are also used in very confined conditions. This makes them the ideal solution for robotics, mounting and handling technolo- gy. These sensors achieve switching frequencies of up to 7000 Hz across a high temperature range.
