Alpha Grey is Alpha's new economy product aimed specifically at the roller shutter market, and designed to compete at a price point that the normal premium Alpha product can’t reach. This is a standard mechanical limits motor, available either with or without a molex connector. Although the normal Alpha motors punch well above their weight in terms of performance, the Alpha Grey motors are not as over-engineered as the premium product but absolutely meet their specifications and are a great reliable motor. The warranty has been reduced to the normal industry standard of 5 years and in the cheaper version of the 2 Alpha Grey motors, the Molex connector has also been removed. This motor simply has a 3m tail without a connector.
All Alpha motors come with a 60mm octagonal drive and crown wheel as standard. See our drive wheel page for others.
