American Cylinder offers a variety of alternatives for pneumatic sensor switches to meet your requirements. Reed Switches are available either with or without indicator lights whereas the Solid State switches all incorporate indicator lights. The color of the Solid State switch's indicator light identifies it as either a NPN (Sinking) switch or a PNP (Sourcing) switch. All switches come with standard 39" leads and can alternatively be ordered with a 6" M8 pigtal type connection. Switches may be ordered individually or as a bore specific assembly that includes a clamping band for easy installation.
