Geared for Speed and Accuracy
Introducing Paquin's new P412 Hand Adjustable Low / Medium Pressure Switch
Field‑settable switching for low and medium pressure applications with rugged construction, flexible terminations, and long service life.
Long-lasting Mechanical Life
-
Built for: industrial machinery, HVAC/refrigeration, water treatment, fluid management, and mobile/heavy equipment.
-
Delivers: hand‑adjustable setpoints, IP65/IP67 ingress protection, and 1M/50k mechanical/electrical life.
-
Integrates via: DIN 43650A, M12x1, AMP Superseal, Deutsch DT, or cable leads (mating connectors available).
What Paquin's P412 Pressure Switch Does
Low/medium‑pressure systems often need frequent setpoint tweaks as loads and media change. Tool‑required adjustments extend downtime. The P412 solves this with a hand‑turn housing that lets technicians dial in the trip point quickly—then lock it in.
What’s New / Why It’s Different
-
Hand‑adjustable setpoint (no tools).
-
Five range options from 10 to 750 psi to fit diverse duties.
-
Contact flexibility: SPST‑NO, SPST‑NC, or SPDT.
-
Ingress options: IP65 (with DIN 43650A & approved connector) or IP67 (others).
-
Rugged construction: brass or 304 stainless body; seal options for broad media and temperature windows.
Applications
-
Industrial machinery & manufacturing equipment
-
HVAC & refrigeration
-
Water treatment / general fluid management
-
Mobile/heavy equipment & hydraulic compactors
