Factor 1 sensors incorporate a Balluff-developed multi coil design that enables them to sense all metals – both ferrous and non-ferrous – at the same distance. Standard M8, M12, and M18 sizes are available in the tubular style and 40x40x40 mm in block style. See all Factor 1 sensors available

• Weld field-immune to 100kA/m
• Never have to be de-rated because they sense all metals at their fully rated sensing distance
• Available with PTFE coating on the housing and end cap 

Factor 1 sensors were designed with welding applications specifically in mind. The PTFE coating helps protect the sensor from weld slag and weld flash generated during the welding process. Additionally, Balluff currently offers many Factor 1 models with SlagMaster™ coating. Applied to the face of the sensor, SlagMaster coating is a major advance over PTFE coated sensors.

Beyond their enhanced application flexibility, Balluff Factor 1 sensors also provide the opportunity to standardize on a smaller number of sensor designs, which can lower supply chain and tool crib stocking costs, especially for welding operations. They also offer attractive pricing advantages because they are positioned between standard and weld-field immune products.
