Baumer OG90 Incremental Encoder Inquiry Item

This Baumer OG90 is a heavy-duty optical incremental encoder, originally from Hübner, now Baumer brand. It adopts optical sensing principle, outputs A/B/Z phase differential signals, supports TTL/RS422 or HTL output according to configuration. It is equipped with B10 EURO standard flange, solid stainless steel shaft structure, strong anti-vibration and anti-shock performance. It is widely used for speed measurement and position feedback of large motors, hoisting equipment, metallurgy and wind power machinery. The resolution can be customized from 1024 to 10000 pulses per revolution. This is a reliable spare part for industrial drive and speed control system.
