Proximity Level Switches – Models PAC-30U and PDC-30
The models PAC-30U and PDC-30 proximity bin level switches are solid state point level devices used to detect the absence or presence of bulk solids. The compact configuration makes this product ideal for tight spaces or low cost level detection. As material comes in contact with, or in close proximity to, the PAC-30U or PDC-30, an internal solid state switch is activated. The PAC-30U is AC operated (20-265 VAC) and is universal in that it is switch selectable for either normally open or normally closed operation. The PDC-30 is DC operated (10-40 VDC) and is available in either PNP or NPN configuration, each of which can be wired in either a normally open or normally closed operation mode.
