The F-5300 Series Low Differential Pressure Switches interface from pressure to electrical controls circuits. They're designed for a low difference between "ON" an "OFF" pressure. The switch is adjustable 0.5 to 100 PSI with 100 PSI maximum supply pressure.

The Switches have three electrical terminals: Normally Open, Normally Closed and Common. 0.1 and 4 AMP switches are available. 4 AMP switch is standard.

Four mounting styles are available: The standard flush mount; the panel mount has a unique thread that goes from 1/8-27 tapered pipe thread to 1/8-27 straight pipe thread for mounting; the manifold mount is designed to mount directly on pneumatic circuit boards or manifold subplates - a Buna N o-ring is supplied; and 1/8 NPT mount which has a 1/8-27 tapered pipe threads. The switches are furnished with a B80 Barb, 10-32 Barbed Fitting for 1/16" I.D. tubing.
