Overview
Standard-housing analog absolute encoders (SAS-M58) with current output are designed to provide reliable absolute position feedback in industrial automation systems. The 4–20 mA or 0–20 mA output ensures compatibility with standard industrial controllers, PLCs, and data acquisition systems, enabling deterministic position monitoring even over long cable distances.
The 58 mm standard housing balances compactness, mechanical robustness, and ease of integration, making it suitable for both new machinery and retrofit projects.
Key Functional Features
- Analog Current Output: 4–20 mA or 0–20 mA for absolute position feedback
- Single-turn resolution: high-resolution encoding up to 16–21 bits (application dependent)
- Multi-turn capability: up to 14 bits (where applicable)
- Stable analog signal in electrically noisy industrial environments
- Environmental protection: IP65 / IP67
- Shock and vibration resistance suitable for industrial operation
These features provide reliable feedback for motion control, positioning, and monitoring systems in industrial automation.
Mechanical Design and Mounting
SAS-M58 analog current encoders are offered in standard housing, supporting:
- Clamp flange – for repeatable and flexible installation
- Blind hollow shaft flange – for integration onto existing shafts
The mechanical design ensures stable operation while allowing easy integration into a wide range of motion systems.
Shaft Interface Options
- Solid Shaft – ideal when shaft alignment is controllable, providing a stable mechanical reference
- Blind Hollow Shaft – suitable for retrofits or space-constrained layouts
Proper selection of the shaft interface ensures accurate signal transmission and long-term reliability.
Environmental Suitability
- Intended for indoor industrial environments
- Moderate temperature operation
- Controlled exposure to dust and moisture
Proper cable management and grounding are recommended to maintain stable current signal transmission.
Typical Applications
- Servo drives and rotary axes
- Conveyor and material handling systems
- Packaging machinery and assembly lines
- Retrofit replacements for legacy analog feedback devices
The standard housing allows mechanical flexibility for diverse machine layouts.
