Optical rotary encoders with hollow shaft up to 80 mm
The optical rotary encoders FGH 8 with a through hollow shaft up to Ø 80 mm are suited for speed monitoring and speed measurement under severe environmental conditions. Thanks to their flat design, they are ideal for attaching additional sensors such as speed switches, absolute encoders or a combination of these. In addition, there is the possibility of a redundant design with two identical scanning systems and evaluation electronics.
The optical rotary encoders are attached directly onto the application shaft or to the application shaft by using a suitable adapter flange.
Reliable
The optical rotary encoders of the FGH 8 series offer a long service life and a very high level of reliability – even under severe ambient conditions.
- Large bearings with high dynamic load rating
- Extremely robust, thick-walled housing
- High shock and vibration resistance
- Compensation of large axial shaft movement
- Saltwater-proof, wet areas in rolling mills
- Temperature range -25 °C up to +85 °C
Safe
The modern electronics of the optical rotary encoders are characterized by electromagnetic compatibility (EMC). It is embedded in a robust, thick-walled housing.
- Up to 4096 pulses HTL / TTL
- Maximum frequency: 3000 rpm
- EMC cable glands
- Options: direction of rotation / standstill detection, isolated adapter flange
Tailor-made
The optical rotary encoders of the FGH 8 series offer a wide variety of device and signal options and can be supplemented by attaching up to 3 further encoders.
