GSA-C Series CANopen Single Turn Bus-based Absolute Encoder

short description:

GSA-C Series Encoder is a single turn CANopen interface absolute encoder, CANopen is a CAN-based communication system. It comprises higher-layer protocols and profile specifications. CANopen has been developed as a standardized embedded network with highly flexible configuration capabilities. It was designed originally for motion-oriented machine control systems, such as handling systems. Today it is used in various application fields, such as medical equipment, off-road vehicles, maritime electronics, railway applications, or building automation.

5. Encoder Selection Guide (Five Steps)

Step	Action	Details
1	Compare with Existing Brands	If you have used encoders from other brands, please provide the relevant details (such as model numbers) so that our engineers can recommend a cost-effective equivalent replacement.
2	Choose the Encoder Type	Options include: incremental encoder, absolute encoder, draw-wire sensor, or manual pulse generator.
3	Choose the Output Format/Interface	For incremental encoders: NPN, PNP, line driver, or push-pull output; for absolute encoders: interfaces such as Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power‑link, and Modbus TCP.
4	Select the Encoder Resolution	For Gertech: up to 50,000 ppr for incremental encoders; up to 29-bit for absolute encoders.
5	Select the Housing and Shaft Diameters	Choose according to your application requirements (for example, this model has a housing diameter of 58 mm and a shaft diameter of 12 mm).
