Renishaw: SiGNUM Si Interfaces A-9572-1521

Renishaw’s SR readhead and Si interface are part of the SiGNUM range of optical encoders.

They have been designed for use with Renishaw’s range of high-accuracy RESM and REXM angle encoders and RSLM and RELM linear encoders which incorporate the IN-TRAC ™ bi-directional reference mark.

The interface incorporates dynamic signal control which, combined with the patented filtering optics, ensure excellent signal integrity and exceptionally low cyclic error.

The Si interface can be mounted remotely and a small connector on the readhead cable allows it to be fed easily through machines where access is restricted.

Dynamic signal control

• Real-time signal conditioning for optimized performance across a range of operating conditions

• Includes Auto Gain Control (AGC), Auto Offset Control (AOC) and Auto Balance Control (ABC)

• Ultra-low cyclic errors, typically ±30 nm

Calibration at the touch of a button

• Click of a mouse via SiGNUM software or CAL button on Si interface

• Optimization for all output signals

Integrated LED diagnostics

• Simplifies initial alignment and set-up

• Reference mark and limit status
