Interfaces ease prototyping

A SICK (UK) product story
Edited by the Engineeringtalk editorial team Apr 11, 2007

Sick's new interfaces allow customers to take advantage of a full range of Hiperface motor feedback encoders and use them in conventional industrial applications.

Sick has launched interface modules provide an electronic gateway between Hiperface and SSI or Profibus.

They will enable customers to take advantage of a full range of Hiperface motor feedback encoders and use them in conventional industrial applications.

These new interface modules open a whole raft of new market opportunities for manufacturers, OEMs and end users.

New applications can now be quickly prototyped and developed using a Profibus or SSI adapter that will communicate with the full range of Hiperface motor-feedback encoders.

DeviceNet, CANopen and Ethernet versions will follow, expanding the possibilities yet further.

The adapter will handle single and multi-turn absolute encoding products, and all multi-turn variants using a gearing system to form positional values with no battery buffered memory.

The adapter will also process linear encoders capable of measuring lengths up to 40m.

Thanks to the adapter, designers of PLC-based architectures now have access to a wide encoder product range, from small units with a body diameter of 36mm to units with a 53mm diameter hollow shaft.

Other variants include those with fully sealed, IP65-rated bodies and units for building into customers' own housings.

There is also a choice of products for low-end applications, for example 512 steps/turn (9 bit) and products for high-end applications, for example 262,144 steps/turn (18 bit).

The interface will allow some installations to be split into two components; an encoder located in a harsh environment, and the electronics performing the evaluation of the raw encoder data in a cabinet up to 100m away.

Hiperface encoders have high resistance to shock and vibration and a high operating temperature range - key requirements for a device designed to fit to the back of a servomotor.

Many industrial applications require this too: power presses, metal processing, foundries and steel/aluminium manufacture, for example.
