Contrinex Introduces Extreme Inductive Sensors for Demanding Industrial Environments & Durability

Contrinex has expanded its industrial automation sensor portfolio with the Full Inox family of extreme inductive sensors designed for harsh manufacturing environments. These sensors utilize a one-piece stainless-steel housing to ensure consistent target detection across heavy-duty application areas such as machining, automotive assembly, and chemical processing.

One-Piece Stainless-Steel Construction and Environmental Sealing
The structural integrity of the sensors relies on a single-piece stainless-steel housing constructed from V2A/AISI 303 grade material. This design provides direct resistance to corrosive chemicals and industrial oils, while sustaining operational integrity under mechanical pressures up to 100 bar. Furthermore, the cable entry is hermetically sealed to prevent moisture ingress. These physical characteristics allow the sensors to achieve IP68 and IP69K protection ratings, certifying their capability to withstand continuous dust exposure, submersion, and high-pressure washdown procedures typical in demanding industrial sectors. This rugged construction minimizes hardware degradation, directly reducing the maintenance requirements and operational downtime associated with sensor failure.

Factor 1 Technology for Consistent Sensing Distances
A core technical feature of the system is the integration of Factor 1 technology, which normalizes the sensing distance across different metal types. Unlike traditional inductive sensors that experience detection range reductions when switching from ferrous to non-ferrous metals, these sensors maintain equal sensing distances for both steel and aluminum targets. This capability streamlines installation in mixed-material environments and reduces the need for constant recalibration. The sensors provide detection ranges of up to 40 millimeters and are manufactured in standardized industrial housing formats, specifically M8, M12, M18, M30, and C23. This physical flexibility allows integration into various machine configurations without requiring extensive mechanical redesign.

Within the domain of Factor 1 and full-metal inductive sensors, the primary comparable technologies are the Turck uprox+ series and the IFM Electronic full-metal proximity sensors. Both the Contrinex and Turck systems utilize multi-coil Factor 1 technology to achieve uniform sensing distances of up to 40 millimeters across different metals without manual adjustment. However, Contrinex prioritizes mechanical resilience against extreme pressure, explicitly rating the sensor face for 100 bar of pressure. In contrast, while IFM Electronic offers competing full-metal, IP68 and IP69K rated sensors, those are frequently manufactured using V4A (AISI 316L) stainless steel to specifically target food and beverage hygienic compliance. Contrinex utilizes V2A (AISI 303) stainless steel, positioning its Full Inox family more squarely toward general heavy machining, high-pressure equipment, and automotive manufacturing where impact resistance and high-pressure fluid tolerance are the primary benchmark criteria.
