Sensor products deployed in harsh environments demand specific housing and sealing techniques as protection against prevailing adverse conditions. Typical applications include the offshore industry, chemical industry, and container ship loading facilities. Encoders installed there must withstand salty air, aggressive media and lubricants, oils and cleaning agents. Baumer offers a wide range of stainless steel encoder designs that meet all these demanding requirements.
The Baumer encoder portfolio comprises incremental and absolute encoders that come in stainless steel housings and are intended for operation under extreme ambient conditions. The compact encoders are available with all common housings, as solid or hollow shaft designs and provide IP68 and 69K protection. For demanding applications in potentially explosive atmospheres there are ATEX-certified variants. Thanks to the interface versatility the encoders offer a high degree of flexibility for easy integration into automation systems. Users can choose between SSI, fieldbus and Ethernet interfaces such as CANopen, DeviceNet, EtherCAT, EtherNet/IP, SAEJ1939, Profibus, PROFINET or POWERLINK.
A highlight in the stainless steel encoder range is the absolute multiturn encoder series “MAGRES hermetic“ with hermetically encapsulated electronics and sensing. Impermeable to fluids, the encoders provide IP68 and IP69K protection. The absolute encoder GE404 with optical sensing comes in an extremely reliable V4-A stainless steel design compliant to class 1.4404 or 1.4435. Viton seals are ultra-resistant against chemicals and high temperature. Incremental signal tracks are available as an option for simultaneous detection of rotational speed and velocity. Lastly, the multiturn-encoder series GEMMH excels with the modular bus cover concept. A modular bus cover hosting the required fieldbus electronics docks onto the basic encoder model.
