The SCR050 stage utilizes a S040 Linear Shaft Motor, making it a compact, precise solution for

small-scale stage applications. The encoder and motor cables are built into the stationary base

and are designed so there is no need for them to bend and flex. All SCR stages utilize a moving

magnet design. With a built-in optical linear encoder that provides sub-nanometer resolution,

the SCR050 is a complete compact stage solution for small-scale precision movement.

Each SCR stage requires a servo driver to operate the stage. Any two SCR stages will

bolt directly together to form a very stiff, compact X-Y assembly, without the need for adaptor

plates. Two SCR stages can be supplied as an X-Y stage to insure true orthogonal orientation
