Incremental optical angular encoder for CLA
360 angular degrees measuring range, endless
Optical fiber based
Material: stainless steel, glass
Encoder can be switched “off” for zero dissipation
Non magnetic version available
The Cryo Optical Encoder (COE) is an incremental non-contact angular encoder. It offers 360 angular degrees measuring range without blind spots, yielding submicron translational resolution when used with a Cryo Linear Actuator (CLA). It is optical fiber based and all electronics are placed in ambient. Only the encoder head with a 200mm fiber pigtail is placed in the cryostat, dissipating no more than a few microWatts when measuring.
