6. Ordering and Selection Process

StepDescription
1If you have used encoders from other brands, please provide the brand and model information. Our engineers will advise you on a high cost-performance equivalent replacement.
2Choose your encoder type: Incremental Encoder, Absolute Encoder, Draw Wire Sensor, or Manual Pulse Generator.
3Select the output format (for incremental encoders: choose among NPN/PNP/Line Driver/Push Pull) or the interface (Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power Link, Modbus TCP).
4Choose the resolution: Up to 50000 ppr for Gertech Incremental Encoders, up to 29 bits for Gertech Absolute Encoders.
5Select the housing diameter and shaft diameter of the encoder.
