Photoelectric, inductive and process sensing devices
A replacement sensor has to agree on four things: sensing method, supply voltage, output type, and how it mounts. Miss one and the input card never sees a state change. Passing through this page have been photoelectric units such as the Allen-Bradley 42SMP-7321-QD, optical sensors off web and press equipment, and process transmitters like the Foxboro PH10 pH/ORP head.
Listing photos include the body markings and nameplate, which matters when a single family spans a dozen suffixes. Start with the number printed on the old sensor; if it has rubbed off, count the conductors and note the cable colors before you call 585-295-7880. More of that brand is grouped on the Allen-Bradley parts page.
