Single-turn Absolute Encoder A/958HS
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
In demanding industrial environments, the need for precise positioning without interrupting the process for constant homing is critical. The A/958HS offers a complete solution that eliminates reliance on external signals to determine the initial position, ensuring immediate operational continuity after any stoppage.
The SSI architecture enables external clock-controlled data transmission, sending the angular position value from the MSB. With a standard 16-bit resolution and RS422 compatibility, the system ensures robust communication at clock frequencies between 100 kHz and 800 kHz in high-speed applications.
The robust housing supports mounting via servo-mount clips or front screws, ensuring mechanical stability. The design protects internal components from dust and impacts, enabling reliable operation in extreme conditions from -40 to +85 °C. Available in guemisa.es.
- High resolution of 16 bits per revolution with custom configuration option.
- Surge protection and SMD technology for greater durability in the field.
- Service life exceeding 10^5 hours of continuous operation at 1000 rpm.
- EMC certification according to EN 61000-6-2 and EN 61000-6-4 for electromagnetically noisy environments.
Technical Frequently Asked Questions
How does the standard SSI output differ from the preset model?
The (SL) variant uses only the SSI protocol for position reading. The (S1) option adds a preset command, allowing the angular position to be reset to zero via an external signal without physically stopping the axis or performing mechanical homing.
What alignment precautions are required for the A/958HS shaft during assembly?
The shaft must be perfectly centered and free of axial play to prevent premature wear of the sealed bearings. A controlled coupling torque is recommended, as the maximum permissible load is 40/110 N radial/axial; exceeding this limit could compromise the encoder's integrity.
What connectors and output options are available for the A/958HS?
IP65-rated axial or radial 12-pin connectors with 1-meter cables are available. Additionally, there are variants with stainless steel housings (code Q) and sealed bearings (code W), as well as surge protection (code X) for critical applications.
What are the permissible operating limits for temperature and humidity?
The device operates stably between -40 °C and +85 °C both during operation and in storage. The maximum permissible relative humidity is 98% without liquid condensation, allowing for installation outdoors or in areas with high industrial climate variability.
How is the SSI signal integrated with external control systems?
The transmission follows the RS422 standard, allowing an adjustable clock frequency between 100 kHz and 800 kHz. The position value is stored internally before being sent from the MSB, facilitating integration with PLCs or controllers that require high-speed reading without saturating the line.
