2.1 Intended Use
The N-412 is a laboratory device as defined by DIN EN 61010-1. It is intended to be used in
interior spaces and in an environment which is free of dirt, oil, and lubricants.
The N-412 is a linear drive for integration in motion systems that are used for positioning,
adjustment and motion of an object (load) in one axis. For integration, the mechanics in which
the N-412 is to be installed must have suitable guides. The N-412 can be mounted horizontally
or vertically.
The N-412 linear drive uses the principle of inertia (stick-slip effect). The feed of the moving
part is produced by alternating static and sliding friction between the moving part and a
cyclically activated piezo actuator. The object to be moved (load) is coupled to the moving part
of the N-412.
When at rest, the drive is self-locking, requires no current and generates no heat. It holds the
position with maximum force.
The N-412 is not intended for continuous operation. For further information on the operating
conditions of the N-412, see “Technical Data” (p. 20).

2 Safety
N-412 Piezo Motor Rod Drive N412T0001 Version: 1.2.1 8
