SMC Electronic Switch Series Variations Remove the gauge and balance the bridge circuit (P1 = P2) by adjusting the variable orifice (S3) via the adjustment knob. By moving the work piece away from the nozzle (S4) a pressure differential (P1 P2) is created. As soon as the work piece is moved within the detection range of the AirCatch Sensor the back pressure P2 increases.

The valve element for the C.O. type, which has no return spring, is in an arbitrary position when air is exhausted through the ports P1 and P2. When pressurized air enters the port P1 (exhaust from the port P2), the valve element opens, and it closes when pressurized air enters the port P2 (exhaust from the port P1).
