Product Description
Compensatory rotor coupling

A separate rotor coupling is used to couple the rotary encoder. This coupling compensates for axial movements, radial misalignment, and angular offset, thereby preventing loads on the rotary encoder's bearing and a reduction in service life.

Wide variety of interfaces

The rotary encoders of the ROD 400 series are available with various interfaces, allowing them to be connected directly to most subsequent electronics. Neither an adapter nor a signal converter is necessary.

Versatile mounting

The rotary encoders of this series can be mounted in different ways. Based on the given requirements, this can be achieved with front-face fastening threads or via clamping with a centering collar.

Proven standard

The rotary encoders of this series boast high reliability and perfected technology in a robust design. For decades, they have proven themselves around the world in great numbers and in a wide variety of applications.
