Introduction
BEI Sensors DXO5 Series Hollow Shaft Stainless Steel Incremental Encoders are built from a solid and reliable mechanical and electrical platform. This product series was built from the ground up for reliability and robustness. Electrical protection is built in to reduce “first installation” errors. Mechanically, the high precision bearings coupled with performant sealing mean long life, even in harsh conditions. The product is tested and rated to perform from –40°C to +100°C for operation in extreme environments. This is the best all-around encoder in a 58mm package for heavy-duty industrial use.
