Balluff Factor 1+ inductive proximity sensors

Balluff has expanded its Factor 1 series of inductive proximity sensors to now include a weld-immune Factor 1+ version with longer sensing distances. Factor 1+ sensors incorporate a multicoil design that enables them to sense all metals - both ferrous and nonferrous - at the same distance without the need to de-rate the sensing distance based on target material. These sensors are suitable for use in applications where sensors encounter high levels of magnetic interference from sources such as transformers, motors, drives or welders.

Factor 1+ sensors offer greater switching distances for increased performance, and greater reliability with vibrating objects. The housing and sensor identification are optimised to meet the requirements of the automobile industry and are 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. Beyond their enhanced application flexibility, Balluff Factor 1+ sensors also provide the opportunity to standardise on a smaller number of sensor designs, which can lower supply chain and tool crib stocking costs, especially for welding operations.
