OMEGA's affordable, general purpose pressure switches offer distinct advantages over most similar style switches, including DPDT or adjustable deadband switches, as well as a wide selection of adjustable ranges from 0.5 inH2O to 3000 psi.
SPECIFICATIONS Approval: UL listed, Storage Temperature: -55 to 70°C (-67 to 158°F) Process Temperature: Stainless Steel: -55 to 205°C (-67 to 401°F) Phosphor Bronze: -40 to 150°C (-40 to 302°F) Buna-N: -25 to 95°C (-13 to 203°F) Ambient Temperature: -40 to 70°C (-40 to 158°F), except models PSW-107 to PSW-117 and PSW-134 to PSW-139: -20 to 70°C (-4 to 158°F). Setpoint typically shifts less than 1% of range for a 30°C (54°F) ambient temperature change. Shock: Setpoint repeats after 15 g, 10 ms duration. Vibration: Setpoint repeats after 2.5 g, 5 to 500 Hz SetPoint Repeatability: All models ±1% of adjustable range, except models PSW-118 to PSW-125 and PSW-132 to PSW-133 are ±1.5% Switch Output: One SPDT or DPDT switch may be wired normally open or normally closed Electrical Rating: Standard 15 A 125/250/480 Vac resistive External Manual Reset: 15 A 125/250 Vac resistive Double Pole Double Throw: 10 A 125/250 Vac resistive Enclosure: Die cast aluminum (max. 0.6% copper). Epoxy-coated blue enclosure, gasketed, complies with NEMA-4X Weight: Approximately 0.9 kg (2 lb) Electrical Connection: 1/2 NPT and Two 7/8" diameter knockouts Dimensions: 191 max H x 101 W x 60 mm D (7.5 max 4 x 2.3")
† All amounts shown in USD Note: When choosing a pressure range it is recommended that the switch operates in the middle 80% of it's adjustable range. Switching may not be accurate in the lower and upper 10% of the range.
