Factor 1 sensors detect objects such as steel, aluminum or brass at the same switching distance (no reduction factor).

These property offers advantages in applications where the material of the target object can vary. In addition, all Factor 1 sensors are magnetic field immune.
They remain unaffected by strong electromagnetic fields from induction hardening or welding equipment and the like. Factor 1 sensors can tolerate welding currents of up to 25 kA with no affect on their switching behavior (at a distance of approx. 5 cm from the current carrying cable).
