Inductive Technology
Inductive proximity switches utilize specialized multi-coil designs to detect both ferrous and non-ferrous metals at identical distances. This specific design, widely known as a factor 1 sensor, replaces the single coil of standard sensors with separate emitting and receiving coils. The internal microcontroller evaluates the phase shifts instead of simple amplitude drops.
By utilizing this dual-coil arrangement, the device overcomes the reduction factors that typically limit the range of standard inductive sensors when measuring aluminum or copper.
Target Response
Metal targets of varying composition produce equal response distances. The factor 1 sensor maintains a constant switching point regardless of whether the target is iron, stainless steel, brass or aluminum. This constant performance simplifies industrial automation by eliminating the need to adjust physical sensor positions for different production runs.
Calibration Procedure
Instrument sourcing requires verifying the sensing threshold against certified metallic blocks. The factor 1 sensor undergoes testing under reference conditions to confirm that the switching point remains within specified tolerances. Lab technicians measure the actual switching distance using a high-precision micrometer stage.
A formal certificate document lists the deviation for each metal type.
Installation Effect
High electromagnetic fields from welding equipment can cause signal distortion. The factor 1 sensor requires shielding to prevent electrical noise from causing premature switching. Nearby metallic structures must remain outside the active field to avoid sensor lockup.
