Six volt (-AA), 12 volt (-AB), and 24 volt (-AC) windings are available with each gear ratio to match a wide range of application needs. The 0.63-in. OD by 0.63-in. long planetary gearboxes are integrated with the DC motor to create a gear motor package. A 30:1 gear ratio is used with the HG 16-030 model; a 60:1 gear ratio with the HG 16-060 model; and 120:1 and 240:1 gear ratios with the HG 16-120 and HG 16-240 models, respectively.A total of 12 models are available depending on the input voltages and gearbox ratios. Nidec-Copal can supply all models with a 0.06-in. OD (1.5-mm) rear shaft for encoders.
