Magnetic hollow-shaft encoders, hermetically-sealed magnetic encoders and heavy-duty encoders detect wear and maintenance issues. Baumer’s line of encoders can be mounted onto generator shafts up to 740 mm in diameter and feature a 27 mm profile. HDMag encoders provide 17-bit single-turn resolution, which provides accurate speed, rotation and position data even in low RPMs. With FPGA signal processing, the encoders are precise, generating maximum incremental square pulses of 524,288 periods per revolution and a maximum sine/cosine interpolation of 32,768 periods per revolution. Consisting of an IP68 stainless steel encoder wheel and an IP67-rated sensing head, the encoders have no moving parts, light source, or glass/breakable components.
The manufacturer also offers Magres magnetic encoders, which are hermetically sealed and IP69K-rated. The encoders are also protected from salt, dust, temperature extremes, moisture and other contaminants.The manufacturer’s most recent encoders feature enhanced monitoring systems that notify the user in advance about wear and maintenance issues. A function-checking system is embedded into the encoder to monitor all functions over the full speed range and to alarm if needed.
