Optical encoders boast top resolution
New high-resolution incremental optical encoders are designed for industrial applications in high precision positioning and measuring systems.
New from Computer Optical Products, CP850/950-HHC series high-resolution incremental optical encoders are available in shafted or blind-hollow shaft versions, and are designed for industrial applications that require high resolution in high precision positioning and measuring systems These cost-effective rotary optical encoders are available in 35 different resolutions, ranging from 25,000 up to 1,250,000 full quadrature A and B cycles per revolution, if used with edge detection 100,000 to 5,000,000 pulses per revolution, respectively

Flexible bar code scanner designed to adapt
Thanks to the Adaptascan's autofocus capability and WindowsT-based configuration software, changes in focus, scan pattern, label format and communication requirements can be made on-line.
Maximum frequency per channel is 2.5MHz for a maximum of 120rev/min for the 1,250,000 cycles per revolution version.
Absolute accuracy is +/-12arc-sec typical.
These encoders were specifically designed for high resolution/high precision positioning and measuring systems such as scanners, spectrum analysers, tuneable lasers, digitisers, micro lithography equipment, antenna pedestal positioning, high-resolution machine tools, telescope systems and rotary tables.
The model CP-850 comes standard with a 9.53mm shaft, whereas the hollow shaft model CP-950 is available for mounting on shafts with a diameter of up to 12.7mm.
The CP-850 is supplied with either a servo-mount or a square mounting flange, whereas CP-950 units are equipped with a flexible (spring) mount.
Both models are industry-standard size 25 and only 63.5mm in length.
The standard 610mm cable can be ordered as either side or end (axial) exit.
A connector option is available.
IP66-rated sealing is also available for either model.
The output format of both units is standard line driver, complementary A/B quadrature and index signals, RS422 compatible.
Voltage supply is +5V DC at 250mA maximum.
Standard operating temperature range is from -20 to +85C; different ratings are available to special order.
