Festo
194378
Twin-piston cylinder DPZCJ-16-20-P-A-GF
This Festo industrial component, part number 194378, is a double-acting guide drive unit featuring a 16 mm piston diameter, a 20 mm stroke, and a yoke plate design with a 0 mm centre of gravity distance from the working load. It operates at working pressures between 1 and 10 bar using dried compressed air, either lubricated or unlubricated, and incorporates a plain-bearing guide, flexible cushioning rings or plates at both ends, and position detection for proximity sensors. Certified with ATEX category II 2G for gas and II 2D for dust, the unit functions within an explosion-proof ambient temperature range of -5°C to +60°C.
