Cleveland Controls AFS-238 Pressure Switch 0.05-12 in W.C. (1 Pack)

Product Description

The Cleveland Controls AFS-238 is a surface-mount air pressure sensing switch with an adjustable setpoint range for HVAC and proving applications. It uses a diaphragm and calibration spring to actuate a snap-acting SPDT contact and can sense positive, negative, or differential pressure across approximately 0.05 �0.02 to 12.0 in W.C. The switch includes screw terminal electrical connections and ferrule-and-nut compression tubing connectors for 0.25 in OD.

• Setpoint range 0.05 �0.02 to 12.0 in W.C.; field adjustable operate and release ranges
• Snap-acting SPDT switch with screw terminal electrical connection and diaphragm vertical mount
• Two ferrule-and-nut compression connectors accept 0.25 in OD tubing; maximum pressure 0.5 psi; operating temperature -40 to 180 F

Product Highlights

Surface-mount SPDT air pressure switch, adjustable 0.05�12 in W.C., screw terminals, 0.5 psi max
