Single-turn Absolute Encoder A/9115S
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
This A/9115S Single-Turn Absolute Encoder addresses the critical need for precise positioning in harsh industrial environments where conventional sensors fail. Its robust design ensures continuous operation under vibration, shock, and extreme conditions that would halt other standard angular measurement systems.
The technical solution integrates a maximum resolution of 16 bits per revolution with SSI and RS422 interfaces. The LED light source guarantees a lifespan exceeding 100,000 hours, ensuring stable binary data transmission without the need for frequent recalibration during the equipment's lifecycle.
The construction uses stainless steel or aluminum with sealed bearings to support radial and axial loads of up to 12 kg. Available with IP65 connectors, it is ideal for heavy machinery and is available in guemisa.es.
- 16-bit resolution per revolution with ±½ LSB accuracy.
- Stainless steel or aluminum casing for maximum durability.
- IP65 protection on outlet and shaft for dusty environments.
- EMC certified according to EN 61000-6-2 and EN 61000-6-4.
Technical Frequently Asked Questions
What alignment precautions does the A/9115S shaft require?
The 11mm diameter shaft must be perfectly centered to avoid excessive loads on the sealed bearings. A controlled starting torque is recommended, as the bearing life depends on the mechanical load applied during continuous operation and the maximum permissible RPM.
What connectors and output options are available for the A/9115S?
Axial or radial connections with IP65-rated cable are available. An RS422 line controller can be added via an optional code, enabling more robust long-distance transmission. Surge protection options and additional sealed bearings for critical environments are also included.
What are the operating limits of the encoder outdoors?
The device operates between -40 and +85°C with a relative humidity of up to 981% TP3T without condensation. Its EMC certification ensures immunity to electromagnetic interference, and its IP65 protection rating allows for direct installation outdoors or in water-washed areas without risk to the internal optical sensors.
How does the A/9115S integrate with modern control systems?
It uses the standard SSI protocol, transmitting data from the MSB via RS422. The clock frequency can be adjusted between 100 kHz and 800 kHz to synchronize with external controllers. The gray binary output facilitates direct reading by industrial PLCs without the need for additional signal conversion.
What certifications and standards does the A/9115S meet?
The A/9115S is manufactured according to ISO 9001 standards and bears the CE marking and declaration of conformity. It complies with EMC directives according to EN 61000-6-2 and EN 61000-6-4 for electromagnetically demanding environments. Its IP protection rating is certified according to IEC EN 60529, EN 60529, and IEC 529, and it comes with a 2-year warranty from the date of delivery.
