Construction
The GEMU 1230 electrical position indicator is suitable for linear valves with actuator strokes up to 20 mm (actuating travel). It has a corrosion resistant housing and one or two micro switches. Switching rod and actuating spindle have a positive connection without axial play.
The electrical connection is via cable gland.

Features
  • Both micro switches can be continuously and precisely adjusted, independently of each other, via threaded spindles
  • Device can be rotated through 360°
  • Customer-specified connectors available as an option
  • LEDs showing position indication are optional
Advantages
  • Simple mounting and retrofitting to GEMU linear actuators
  • Mounting to other makes upon possible
  • Compact design in a stable housing
  • Protection class IP 65 to EN 60529
