Mechanical Pressure Switches
PS Series
Industrial Pressure Switches
A configurable mechanical pressure-switch family covering low-pressure diaphragm and high-pressure piston applications, with SPST/SPDT options and multiple industrial connectors.
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 INC confirms the controlled specification before order acceptance.
