Encoder Interface Guides

Compare industrial encoder outputs and communication protocols before selecting a product. Every guide connects technical requirements to relevant product pages and a model-confirmation process.

Choose by engineering question, not by catalog name alone.

These pages are organized around the information industrial buyers and engineers need to make a decision: measurement task, controller interface, mechanical fit, operating environment and documentation.

Encoder interface guide

RS485 Modbus RTU Absolute Encoders

An RS485 Modbus RTU absolute encoder reports a digital position value over a noise-resistant differential bus. It is a practical choice when a PLC or industrial controller needs absolute angle or turn data, configurable addressing and longer cable runs. Final selection must match the controller register map, supply, baud rate and mechanical installation.Open technical guide →02

Encoder interface guide

CANopen Absolute Encoders

A CANopen absolute encoder provides position data through a standardized CAN-based device network. It is suited to machines that already use CANopen and need configurable node addressing, position objects and diagnostic behavior. Selection still depends on resolution, single-turn or multi-turn range, mechanical fit, supply and environmental protection.Open technical guide →03

Encoder interface guide

4–20 mA and Voltage Output Position Sensors

Analog position sensors convert absolute angle or linear travel into a PLC-ready current or voltage signal. A 4–20 mA output is generally preferred for longer industrial cable runs and fault detection, while 0–10 V or 0–5 V can suit shorter runs and compatible analog inputs. Output span, supply and scaling must be confirmed together.Open technical guide →04

Encoder interface guide

SSI and BiSS-C Absolute Encoders

SSI and BiSS-C are synchronous serial interfaces used for deterministic absolute position feedback. The controller supplies a clock and the encoder returns a digital position word. They are not automatically interchangeable: clock rate, frame format, bit length, coding, error fields, electrical level and controller support must all match.Open technical guide →05

Encoder interface guide

Incremental A/B/Z Encoder Outputs

An incremental encoder produces A and B pulse channels with a phase offset so the controller can calculate movement and direction. An optional Z index provides a periodic reference, commonly once per revolution. Correct integration requires matching PPR, maximum pulse frequency, output circuit, supply, voltage level and controller counter input.Open technical guide →
