Applicable Auto Switch Model CD-P11 CD-P12 2 Contact Protection Box/Dimensions Contact SMC when using built-in contact protection circuit style (D-A34[A] [C], D-A44[A] [C], D-A54/A64, D-B54/B64, D-A59W, D-B59W) in the following conditions: q The wiring length to load is more than 30m. w When using PLC with large flow current Contact Protection Box/Specifications Load voltage CD-P11 CD-P12 Part No. 100V AC max. 200V AC
Caution q Supply air Be careful not to allow any foreign materials into the supply of the Air Catch Sensor. Contamination of the sensor will decrease the sensors accuracy. Especially important when measuring small bore orifices. Use dry and filtered (5m) supply air. wOperating pressure Do not exceed the max. operating pressure of 0.2 MPa.
Switch assembly Adjusting screw Working principle When the MR units OUT side pressure is applied to piston q, piston q moves until it balances with the force of pressure adjustment spring w. The movement of piston q is detected by switch assembly e and outputs ON and OFF signals. The set pressure can be adjusted by turning adjustment screw r, which adjusts the spring force.
