RANGE0.2 to 400 bar across PS2 / PS3A / PS4
OUTPUTSPST NO/NC or SPDT, model dependent
MATERIALStainless steel with model-specific diaphragm/seal options
PROTECTIONIP00 / IP65 / IP67 / IP68 by termination

Product overview

Application-focused measurement and switching.

The PS Series provides three mechanical sensing architectures for equipment pressure control. PS2 covers low-pressure diaphragm applications, PS3A provides an adjustable piston switch from 10 to 400 bar, and PS4 combines a snap-action contact with a high-pressure diaphragm for 1 to 10 bar switching under system pressures up to 200 bar.

Configuration note

Ratings, materials, interfaces, and approvals can vary by ordered configuration. CASCED US confirms the controlled specification before order acceptance.

Key features

  • Three sensing platforms for low- and high-pressure applications
  • Factory preset or adjustable switching options, model dependent
  • SPST normally-open, SPST normally-closed, and SPDT configurations
  • Broad elastomer, pressure-port, and connector selection
  • PS3A proof pressure up to 600 bar
  • PS4 options aligned with 2014/35/EU LVD and 2011/65/EU RoHS
