Frictionless Miniature
Magnetic Encoders
Renishaw has introduced a range of frictionless miniature magnetic encoders with resolutions from 9-bit (512 counts per revolution) to 12-bit (4,096 counts per revolution).
Why use a frictionless magnetic encoder?
- No seals to leak
- No bearings to fail
- No glass optics to break
- No internal moving parts
- Immunity to dirt, water, oil, dust, grease (sealed to IP68)
- Incremental resolution to 4,096 steps
- Absolute resolution to 12 bits
- High speed operation to 30,000 rpm
- Angular accuracy to 0.2°
The new range of rotary magnetic encoders is easy to integrate, with a range of formats offered, including component, modular and packaged versions. Output signal types include industry standard absolute, incremental, analogue, linear voltage and linear current.
With such a flexible design, a wide range of applications will benefit from these new encoders, including marine, medical, print, converting, industrial automation, metal working, motor control and instrumentation.
RE22 9-bit 5V
A range of miniature magnetic rotary encoders
The RE22 is a compact, high-speed rotary magnetic encoder designed for use in harsh environments. The traditional design allows for easy integration to existing machines.
A magnet is mounted to the shaft within the encoder body. Rotation of this magnet is sensed by a custom encoder chip within the body, and processed to give the required output format.
The encoder chip processes the signals received to provide resolutions of 9 bit (512 positions per revolution) with operational speeds to 20,000 rpm. Output signals are provided in industry standard absolute, incremental or analog formats.
The compact encoder body is just 22 mm in diameter and provides dirt immunity to IP68. The RE22 can be used in a wide range of applications including marine, medical, print, converting, industrial automation, metal working and instrumentation.
- Excellent immunity to IP68
- High speed operation to 20,000 rpm
- Compact - 22 mm diameter body
- Absolute - 9 bit (512 counts per revolution)
- Industry standard absolute, incremental and analogue output formats
- Accuracy ± 1 bit (±0.7°)
- Power supply 5V
- Simple integration
RE36 5V and 24V
A range of high speed magnetic rotary encoders
The RE36 is a high-speed rotary magnetic encoder designed for use in harsh environments. The traditional design allows for easy integration to existing machines.
A magnet is mounted to the shaft within the encoder body. Rotation of this magnet is sensed by a custom encoder chip within the body, and processed to give the required output format.
