DC Metallic-Object Proximity Switches for Long Distances
Sense objects from farther away than with other proximity switches that have the same diameter. Also known as inductive proximity switches, they remotely sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. Sensing distance is based on the type of material being sensed. The distance listed is for mild steel. They’re often used with programmable logic controllers (PLCs) and produce PNP signal output.
Flush switches, also known as embeddable or shielded switches, can be mounted so that the sensor face is level with the surface of any material, including metal. They’re more accurate than projecting switches at close range and can be mounted close together without causing interference.
Switches with IO Link can be configured remotely when connected to a PLC, a human-machine interface (HMI), or a computer. They let you remotely change your settings, view measurements, and receive error messages.
All are rated IP69K for protection from high-temperature, high-pressure washdowns.
