German 1A CAL sensor 1A CAL model 1A CAL price

1A CAL sensors are a general term for sensors designed to detect objects without physical contact, replacing contact-based detection methods such as limit switches. They convert information about an object's movement and presence into electrical signals. Detection methods that convert to electrical signals include those utilizing eddy currents generated in the metal body of the detected object due to electromagnetic induction, those detecting capacitance changes in the electrical signal caused by the approach of the detected object, and those using reed and guided switches. 1A CAL sensor detection principle detects magnetic losses caused by eddy currents generated on the surface of a conductor through the influence of an external magnetic field.
