Digisine is a new generation of incremental encoders suitable for a wide range of demanding industrial applications.
Digisine is a new generation of incremental encoders suitable for a wide range of demanding industrial applications.
The high quality range sets new standards for temperature rating, frequency response, mechanical durability and configuration flexibility.
With an operating temperature range from -40 to +100C and a standard frequency response of 300kHz, the performance of the Digisine range significantly exceeds the European standard.
The robust design features rigid bearings, which allow extremely high axial and radial loads.
The use of a new generation LED reduces problems due to ageing and extreme temperature conditions.
Digisine can be adapted to suit multiple configurations and can deliver square-wave or sinewave output signals in one, two or three channels at even the highest resolutions.
For square-wave signals the internal interpolation in the encoder electronics brings the resolution up to 80,000 counts per turn.
For applications requiring high precision, for example in machine tools, the sinewave signal can be interpolated by external electronics to give a resolution of several million counts per turn.
Programming of the encoder resolution is by means of DIP switches, which allow the internal interpolation factor to be set in multiples of two up to 16 times the basic resolution of the optical disc.
The universal circuitry is suitable for use with supply voltages in the range 5 to 30V DC and the output stages are either push/pull, in voltages from 4.5 to 30V DC or regulated 5V DC for RS422 interfaces.
Digisine encoders are available as shafted or hollow shaft versions to cover a range of applications.
The shafted versions have diameters of 6 and 10mm and are compatible with other ranges of BEI Ideacod encoders and encoders from other manufacturers.
Hollow shafts are available in a standard shaft diameter of 14mm with 6, 8, 10 and 12mm options available using aluminium reduction hubs.
The enclosure is rated to IP65 as standard and can be easily configured to IP67 with the addition of a sealing flange.
Encoders can be mounted together to allow double or triple configurations to provide different resolution signals or built in redundancy.
There is a full range of accessories available including flanges, couplings, mounting brackets, measuring wheels, connectors and cable assemblies.
With the introduction of the Digisine range, design engineers now have access to a robust and reliable range of encoders.
They are flexible in use, easy to mount and are both accurate and reliable.
This new range from BEI Ideacod represents a significant stride forward in encoder technology.
