SED – 024.86 Inductive Position Indicator

NAMUR 2-Wire


  • The inductive position indicator is suitable for linear valves with actuator strokes up to 75mm (actuating travel)
  • It has a corrosion resistant plastic housing and one or two inductive proximity switches acc. to NAMUR EN 50227
  • The electrical connection is via cable gland
  • Both proximity switches can be continuously and precisely adjusted, independently of each other, via threaded spindles
  • Device can be rotated through 360°
  • Simple mounting and retrofitting to linear actuators
  • Compact design in a stable housing
  • The switches are not subject to wear, contactless detection
  • Protection class IP 65 to EN 60529





The SED inductive position indicator type 024.86 enables a perfect control and indication of the open/closed positions of the valve.


The signal is transmitted by two proximity switches. Switches stroke between both spools is linear, and enables an easy employ whenever signal must precisely be repeated. Main features of the indicator type 024.86 are also a total protection against current peaks, and a safe handling.


  • ATEX-marking from the proximity switches:
