Graco's PR70 key-market list names automotive components/electronics first. Family specs: ratio to 24:1 by model, shot size 2.0-70cc, ratio accuracy ±1%; epoxies, sealants, adhesives, silicones, urethanes. This is the benchtop tier — the right answer for low-volume electronics potting where a GSD cell is oversized. Manuals 312761EN-E, 312760EN, 312759EN, 338863EN-D.

PR70 covers 2.0-70cc shots at ±1% accuracy; per Graco's own cross-product comparison table, work needing more than 70cc per shot or a hydraulic drive escalates to HFR, which carries a 30cc minimum shot on that platform.
Electronics assembly at bench scale doesn't need a full automated GSD cell — it needs repeatable ±1% shots in the 2-70cc range. Automotive components/electronics heads Graco's own PR70 key-market list, and picking PR70e vs. PR70s isn't cosmetic: PR70s's unlimited PLC flow selections is what an automated changeover line needs, where PR70e's fixed purge timer is the manual-bench answer.
