Small mounting space

Small mounting space
Scale is tape type with thickness of "0.4 mm", and the outer shape of the head is 50 x 21 x 12

Small mounting space
High resolution High speed

High resolution・High speed
0.1μm・30m/sec

Scale can be cut to desired length

No Air Purge

Excellent environmental resistance
Due to electromagnetic induction, the position can be detected without the affect by oil stains on the pattern.

Various servo-AMP interface

Various servo-AMP interface
MELSERVO, PANASONIC

Stable high accuracy lasted for a long period

Stable high accuracy lasted for a long period
Because the fixed part and movable part do not contact.

Easy adjustment with extensive diagnostic functions

Easy adjustment with extensive diagnostic functions
Convenient, the GAP value and current position are displayed during assembly and maintenance.

Easy adjustment with extensive diagnostic functions
Multi-head is possible

Multi-head is possible
Possible to use heads with different specifications.


High speed・High resolution

0.1μm・30m/sec
Scale is mounted on the stage driven by a linear motor, and high-speed operation is performed with 0.1 μm detection.

Excellent environmental resistance

Since not optical type but "electromagnetic type", not affected by surface dirt.
Even if Scale pattern is dirtied with marker, Scale will work without problems.

Application

Most suitable for detecting the position of high speed stage with linear motor.
In the video example Scale and Head are mounted on the right side of the linear stage.
