Vision and Commitment

GS Linear Optical Scales



The GSs Optical Scales cover all the most common applications for Machine Tools and Measuring Instruments. More in detail:
  • Measurement Travels: from 50 mm to 3 meters
  • Scales Sections: 4 Aluminum bodies are available (GS30 sall size; GS10 and GS50 medium size; GS20 big size)
  • The GS serie includes 5 micron and 1 micron scales in 3 different cross sections (GS 30, GS 10, GS 20) and 2 Output Signals (TTL and RS 422A).

Advanced Optical Measuring System

The slide carrier of the GS series scales, uses a five bearing design for the optical grating linear transducer which has been proven as the most reliable system design in today's market.

The glass grating slideways are lapped, and JIS standard P5 grade bearings are used to achieve smooth and accurate movement and long working life.



Double Seals Design

The plastics seals of GS series scales use an innovative material to offer superior oil resistance,high elastic recovery properties and durability. Carefully designed lips geometry offer low slide resistance.

Connectors, ASIC Interpolator
ASIC Interpolator is built-in inside the GS Series Glass grating linear transducer to facilitate increased resolution of the grating. All frequency multiplication is implemented 100% by hardware phase shifting inside the ASIC interpolator to minimize the real time measurement error. Because all resistor ladders for phase shifting are constructed with same piece of Semiconductor inside the ASIC, which have same temperature coefficient, therefore, the error drift caused by environmental temperature change is minimized.

DSub 9 - DIN 7 Connectors





Industrial Standard Output Signal Interface

The industrial standard TTL &RS-422-A digital signal output are available for user's choice User can choose the most suitable signal interface according to their cost, power & EMI requirements. Standard 9 pin DSUB9 and DIN7 7pin connectors are available for user's choice.

GS Scales use high class electrical cables and stainless steel armoured conduits. For a better Reliability Easson recommends DSub 9 connectors.

All GS scales are Laser inspected with HP Agilent Interferometers.
