Description of the Product
The angle encoders without integral bearing (modular angle encoders) are intended for integration in machine elements or apparatuses. They are suited for the following requirements:
Large hollow shaft diameter (up to 10 m with a scale tape)
High shaft speeds up to 40000 rpm
No additional starting torque from shaft seals
Segment solutions
Angle encoders without integral bearing
The angle encoders without integral bearing (modular angle encoders) ERP, ERO and ERA consist of two components—a scanning head and a graduation carrier, which must be aligned with each other during mounting. The eccentricity of the shaft as well as installation and adjustment therefore have a decisive effect on the achievable accuracy. Modular angle encoders are available with various graduation carriers
• ERP/ERO: Glass circular scale with hub
• ERA 4000: Steel drum
• ERA 7000/8000: Steel tape
Angle encoders without integral bearing are designed for integration in machine elements or components.
They are designed to meet the following requirements:
• Large hollow shaft diameters (up to 10 m with a scale tape)
• High shaft speeds
• No additional starting torque from shaft seals
• High reproducibility
• High adaptability to mounting space
(versions with scale tape available as full circles or circle segments)
Because angle encoders without integral bearing are supplied without enclosure, the
required degree of protection must be ensured through proper installation.
