Industrial SS21-85 Separated Type Speed Controller

Sesame SS21-85 Separated Type Speed Controller is a compact 110V AC speed-control unit from Sesame Motor Corp, part of the SS Series Separated Type line. In this separated-type design, the controller houses the control circuitry, including the capacitor and a variable resistor, and connects to a Sesame motor via an extended cable using an 8-pin interface. The SS21-85 designation identifies this 8-pin, 110V variant within the SS Series family, compatible with Sesame's separated-type motors and gear motors as a modular speed-control package. The separated-type approach means the controller and motor are connected but physically distinct, allowing straightforward substitution or upgrade of either component while maintaining the same control interface. This model is intended for use with standard 110V AC systems in industrial automation environments that employ Sesame's SS-series drive modules.
