Incremental rotary encoders take bigger shocks

A series incremental rotary encoders that are recognized as an industry standard have been redesigned to satisfy applications that require higher shock and vibration load capacity.

What has long been recognized as the industry standard, the Heidenhain ROD 400 and ERN 400 series incremental rotary encoders have gone through a redesign.

Many improvements have been made in order for the encoders to satisfy an even broader range of applications that require higher shock and vibration load capacity.

Specifically, the acceleration load capacity has increased significantly.

All ROD 400s with a cable exit can handle vibrations up to 300m/s2 and shock loads up to 2000 m/s2 allowing them to function under extreme operating conditions.

These encoders also feature a universal cable exit that can be configured for either an axial or radial application.

This enhancement reduces the number of variants thus simplifies the ordering process and increases availability.

Also, realising the importance of available space, the overall encoder length of the ROD/ERN 400 series has been reduced for all variants with a flange socket, allowing the user to take advantage of the smaller size whether using a flange socket or cable.

Finally, for the blind hollow shaft or through-shaft, the new design of these encoders features an improved shaft clamping mechanism for easier and more effective mounting.

Rather than direct contact to the mating shaft via setscrew, Heidenhain has designed a three-point clamping ring that prohibits damage to the mating shaft.
