Tie Rod Mounted - ALS Position Indicator Switch

Brand: Schrader Bellows

Tie Rod Mounted Switches – actuated by a magnetic piston 
  • Can be positioned at any location along the cylinder to indicate end-of-stroke or midstroke locations
  • Allow multiple switches to be installed with numbers only restricted by available tie rod mounting space
  • Are non-intrusive and maintain pressure envelope integrity
  • Available for PH-2 Series in 1.50" - 6.00" bores, PL-2, and PA-2 Series in 1.00" - 4.00" bores.
ALS Switch

Exclusive innovative sensor detects a magnetic piston through a standard steel tube.

They are an economical alternative to Global Switches for long stroke applications that require a stainless steel tube.
Features
  • For magnetic piston sensing through steel tube material 
  • Cost effective alternative to Stainless Steel tube for longer strokes 
  • 4 wire DC connection 
  • PNP and NPN versions can be wired N.O. or N.C. 
  • The ALS Switch is not designed for use with non-ferrous tubes
