Limit Switch

The 300/400FC series Limit switch visual indicator is a mechanical device which graphically displays the angular displacement (rotary indication) of a quarter turn valve for any other device operating between 0°and 90°. The limt switch indicator represents a true indication of valve position. it is infinitely adjustable and delivers a 100% change of indication, displaying 90°of rotation by utilising an amplified mechanical drive.

Integrated Characteristic

  • Suitable for Rotary quarter turn actuator
  • Extremely vibration resistance design
  • Corrosion reisistance aluminium diecast and powder coated
  • Bolts on visual position indicator is adjustable waterproof
  • Easy to adjust cam, spring loaded splined cam. noneed to adjust again after initial setting. easy setting without tool
  • Dual cable entries
  • Captive cover bolts. No worry to loose bolts while cover opens.
  • Easy mounting
  • Optional position transmitter 4~20mA Dc.

Application

The 300FC Limit switchs are used for visual indication and contact output of the rotary quarter turn actuator and optionally get the 4-20mA DC with respect to the rotary valve moment.
