Available under at least 2 names:
Digital Sans EF by Elsner & Flake [1999]
Digital Serial (Bold) by SoftMaker [1991]
The 2nd one is a bit closer to your sample but although is available for purchase from myfonts.com, take into account that it's probably a clone and not an original design as most of SoftMaker's fonts under the '-serial' suffix/trick.
Sol Pro (Medium) by Canada Type [2010] is another similar.
There are also at least 2 similar freebies out there (probably illegal clones).
