Details

Hollow Shaft Space Encoder

 

The VLS series is designed with compact dimensions, light weight, and the signature Netzer hollow shaft for unmatched precision. These characteristics are essential for the demands of space exploration. The VLS range meets the rigorous demands of TID (Total Ionizing Dose) and minimal outgassing, which are key factors for thriving in the harsh environment of space.
