Overview
Standard-housing CANopen absolute encoders (SAS-M58) are designed to deliver precise absolute position feedback in industrial automation systems. With the CANopen interface, these encoders provide deterministic communication suitable for servo drives, conveyor systems, and general automation equipment.
The 58mm housing series offers a balance of compactness, mechanical flexibility, and high-resolution performance, making it ideal for both new machine designs and retrofit applications.
Key Functional Features
- CANopen Interface: CiA 301 & CiA 406 compliant for deterministic absolute position transmission
- Single-turn resolution: up to 21 bits
- Multi-turn resolution: up to 14 bits
- Optional incremental signals for hybrid control applications
- Robust signal integrity in electrically noisy environments
- Environmental protection: IP65 / IP67
- Mechanical durability: resistant to shock and vibration
These characteristics ensure reliable position feedback under typical industrial conditions.
Mechanical Design and Mounting
SAS-M58 encoders are offered in standard housing, supporting:
- Clamp flange – allows repeatable and flexible mounting
- Blind hollow shaft flange – facilitates integration onto an existing shaft
The design provides mechanical stability and ease of installation, supporting a wide range of motion systems.
Shaft Interface Options
- Solid Shaft – used when shaft alignment can be controlled; ensures clear mechanical reference
- Blind Hollow Shaft – allows mounting directly onto the machine shaft; suitable for space-constrained or retrofit applications
Proper shaft selection and alignment are critical to ensure long-term operational reliability.
Environmental Suitability
- Intended for indoor industrial environments
- Suitable for moderate temperature ranges
- Controlled exposure to dust and moisture
Proper cable management and grounding enhance signal stability, particularly in electrically noisy environments.
Typical Applications
- Servo drive systems and machine axes
- Conveyor and material handling equipment
- Packaging and assembly machinery
- Retrofit projects replacing legacy absolute or incremental encoders
Standard housing provides mechanical adaptability for diverse machine layouts.
Engineering Selection Summary
SAS-M58 standard-housing CANopen absolute encoders provide a reliable solution for industrial automation. Their combination of mechanical flexibility, high-resolution SSI feedback, and standardized CANopen communication makes them ideal for both new and existing machine installations. Careful attention to mounting, shaft interface, and environmental conditions ensures long-term performance.
