Industrial sensors deployed outdoors or in hygiene and washdown applications often face challenging conditions, including fluctuating temperatures and frequent cleaning cycles. Even with standard IP ratings like IP 68 or IP 69K, ensuring long-term reliability under these demanding circumstances remains a critical concern.

To address this challenge, Baumer has introduced proTect+, an advanced solution designed to enhance sensor durability through innovative engineering practices. Sensors such as optical and inductive proximity sensors, along with force-measuring devices, are engineered according to proTect+ design guidelines using specialized materials. This meticulous approach ensures superior sealing performance.

The robustness of these sensors is further validated by a rigorous testing protocol that simulates aging effects via temperature shock tests both in air and water before subjecting them to standard IP 68/69K evaluations. As a result, proTect+ certified sensors deliver exceptional long-term sealing integrity throughout their operational lifespan.

Customer feedback from extreme environment applications has been instrumental in refining design principles and manufacturing processes continuously. For instance, the DST55R extension sensor for force measurement was specifically developed to withstand abrasive conditions in mobile automation systems. Combining intelligent structural design with durable materials and advanced sealing technology enables these sensors to maintain accuracy despite exposure to moisture, dust, and repeated cleaning cycles.

Thanks to proTect+, Baumer sensors consistently provide reliable measurements throughout their entire service life—exceeding standard expectations by delivering exceptional performance even under the most demanding operational conditions.
