Dimensions (mm) Panel cut out: Ø16mm Front dimensions: 25 x 25mm Front bezel height: 12mm Travel: 3mm QUARTRON (PDF-22Pg) Schlegel’s Quartron series combines the suitability and toughness of large control units to all kinds of machines with the optimum exploitation of panel surface and the small space requirement of 16mm units. These square control units can be mounted closely together with a mounting grid of 25x25mm. The contact blocks can easily be snapped onto the control units. Quartron units are square with either a black or charcoal bezel, but the mounting hole is 16mm round. This series laid the foundation for leading the market position with 16mm control units.
