GSM Series: Motorized goniometers with Auto Detect
40 mm and 60 mm centre of rotation options allow for two axes of motion about a common centre of rotation
30 N load capacity
Low profile, small footprint
Designed for use with an X-MCC Series stepper motor controller or any 2-phase stepper motor controller
With Auto Detect, the X-MCC controller configures its settings automatically for the connected peripheral
Zaber's GSM Series devices are motorized goniometers with high thrust and speed capabilities in a compact package. They are stepper motor driven positioning goniometers designed to interface with our X-MCC controllers, offering high resolution daisy-chainable operation.
Set up is easy with Auto Detect. Once connected, the X-MCC controller will automatically detect and configure the GSM. These stages are excellent for applications where a small profile is required. They can mount to a flat surface or stack together to share a common centre of rotation for two axes of angular motion.
