Easson linear scale GS10/GS11/GS12/GS13
【Advanced Optical Measuring System】
The slide carrier of the GS series scales, use a five bearing design for optical grating linear transducer which has been proven as the most reliable system design in today’s market. The glass grating slide ways 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
【100%Laser calibration】
All glass grating transducers are individually inspected and calibrated by our in-house laser calibrator to ensure accuracy comply 100% with the specifications.
【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 efficient? Therefore, error drift caused by environmental temperature change is minimized.
【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 inter face according to their cost, power & EMI requirements. Standard 9 pin DSUB9 and DIN7 7pin connectors are available for user’s choice.
