Single-turn Absolute Encoder A/758H
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
The A/758H Single-Turn Absolute Encoder meets the precise positioning needs of demanding industrial machinery. Its robust design allows for direct integration into control systems without additional mechanical complications, ensuring continuous operational reliability under heavy and variable working conditions, and guaranteeing stable operation.
The technical solution integrates a programmable SSI interface with a maximum physical resolution of 65,536 positions (16 bits). This allows for the management of multiple revolutions up to 4,096 rpm without data loss, ideal for applications requiring high accuracy in absolute position transmission and synchronization.
Constructed with an anodized aluminum housing (Ø58 mm) and a stainless steel shaft, it withstands vibrations of 12 G and temperatures between -20 and +85 °C. Available in guemisa.es for immediate implementation in industrial automation projects, guaranteeing impact resistance and durability in harsh environments.
- Programmable resolution up to 65536 positions (16 bits) for high absolute precision.
- Anodized metal housing Ø58 mm with IP65/66 protection against dust and splashes.
- Wide operating temperature range from -20 to +85 °C in industrial applications.
- Superior mechanical resistance to 12 G vibrations and 50 G impacts without failure.
Technical Frequently Asked Questions
How does the A/758H model differ from standard incremental encoders?
The A/758H offers programmable absolute resolution up to 65536, unlike incremental systems that require homing. It supports SSI and RS422 for synchronous transmission without loss of position during power outages.
What alignment precautions are required for the A/758H axle?
The Ø10 mm stainless steel shaft supports a radial/axial load of 2 Kg, but must be installed with precise alignment to avoid misalignments that affect the service life of the sealed bearings and the integrity of the optical sensors.
What programming and interface options are available for the A/758H?
It can be programmed via USB with PC software or via RS422 interface which allows data exchange in ASCII code without additional cables, offering flexibility in SSI or incremental Sin/Cos output configuration.
What are the operational and environmental limits of the A/758H?
It operates between -20 and +85 °C with storage up to +85 °C. It withstands vibrations of 12 G (10 ÷ 2000 Hz) and impacts of 50 G, guaranteeing stability in harsh industrial environments without degradation of electronic performance.
How does the A/758H integrate with existing control systems?
It uses SSI inputs (Clock, DIR, PRESET) for synchronous position transmission. The interface allows configuration of maximum physical resolution and counting direction, facilitating direct connection to PLCs or motion controllers compatible with SSI protocols.
