Modular Design Allows for Fast Delivery
The PSW8 series has been discontinued. Please see the PSW-500 as a possible alternative or contact our Engineering department.
OMEGA’s new modular series general purpose compact
pressure switches, offer a proven design for
stationary or mobile hydraulic applications.
Applications include factory automation, balers,
compactors, overload controls, machine tools,
hydraulic power packs, railway, and marine
applications. PSW8 series is available in a wide
range of configurations. Low pressure ranges
feature a diaphragm pressure switch design.
Higher pressure ranges feature a compact piston
design. A SPDT micro switch will change state on
increasing pressure at your set-point, and will reset
when your pressure decreases back below the
set-point by the amount of the deadband.
SPECIFICATIONS Set-Point Repeatability: Diaphragm Models: ±2% typical Piston Models: ±1% typical Setpoint Adjustment: Upon delivery, set-point is in the middle of the adjustable range. Turn adjustment screw CW to increase, and CCW to decrease. Hysteresis/Deadband: Less than or equal to 15% of maximum adjustable range Contact Rating: 1 Amp: Gold-plated 0.1 A @ 125 Vac, 01. A @ 30 Vdc 5 Amp: Silver 3 A @ 250 Vac, 5 A @ 120 Vac or 0.4 A @ 120 Vdc Wiring: Pin 1: Common Pin 2: Normally closed Pin 3: Normally open Switching Frequency: Maximum 30/minimum for diaphragm models; maximum 60/minimum for piston models Ambient Temperature Range: Diaphragm Models: -20 to 80°C (-4 to 176°F) Piston Models: -40 to 80°C (-40 to 176°F) Wetted Parts: Process Fitting: 304 SS Housing: Aluminum die-cast 230 Seals and Diaphragms: See table, Buna-N or FKM.
