The H-516-6M is a turns-counting dial designed for use with precision potentiometers and other rotating devices up to 15 turns, specifically engineered to accept 6 mm shaft diameters. It features a compact design requiring only 22.8 mm diameter panel space with no backlash, dial divisions of 0.50 per turn, and a readability of 2 parts in 1000 over 10 turns. The unit includes a locking brake with a minimum torque of 5.0 N-cm when engaged, white markings on a black background for clear visibility, and weighs 7 grams. It is designed for use with plastic shafts and is RoHS compliant, making it suitable for precision instrumentation, data acquisition systems, and control applications where accurate turn counting and positioning are essential.
