SSI Absolute Encoders: A Comparison of International Brands and Domestic Alternatives

SSI Absolute Encoder Technology Overview

SSI absolute encoders are industrial sensors that output position information via a synchronized serial interface.
Its communication method is characterized by the master station providing clock signal and the encoder returning absolute position data in fixed time sequence, which has the features of simple structure and strong anti-interference ability.

Typical technical parameter range (engineering direction)

Communication interface: SSI (synchronous serial)
Lap resolution: 12-16 bit (common)
Multi-turn construction: Mechanical
Supply voltage: 10-30 VDC (depending on model)
Output form: pure SSI or SSI + incremental signals

Application Features of International SSI Encoders

International brand SSI encoders are mostly used:
CNC and high-end automation equipment
Continuous operation conditions
Systems with high requirements for long-term stability
The advantages are mainly in terms of long-term engineering validation and standardized interface compatibility.

Feasibility of substituting domestic SSI absolute encoders

In most industrial applications, domestic SSI absolute encoders already fulfill the following needs:
Stabilizes SSI communication timing
Meets medium and high precision positioning requirements
Various mechanical structures and mounting forms
More flexible lead times and local support
