Single-Turn Absolute Encoder A/390CBB
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
In demanding industrial environments, conventional position sensors fail quickly in the presence of oil, dust, and moisture, causing unplanned downtime in heavy machinery that requires absolute reliability to maintain production without costly interruptions for preventive maintenance.
This encoder offers a maximum resolution of 8192 positions with an extremely robust housing designed for heavy and durable loads in critical motion control applications, ensuring the integrity of positional data even under severe operating conditions.
Constructed from anodized aluminum and phototransistors, it withstands shocks of 40 G and vibrations up to 50 kHz. The unit is available in guemisa.es.
- The extremely robust housing resists oil, dust and moisture to ensure long-term reliability in demanding industrial environments without the need for frequent maintenance.
- The insulated through shaft with plastic bushing ensures the electrical integrity of the system against interference in heavy motor control applications.
- The LED light source with an average lifespan exceeding 100,000 hours ensures stable optical operation throughout the equipment's life cycle.
- It supports multiple output codes such as Gray, Binary, and BCD to facilitate integration with various existing industrial control architectures in the plant.
Technical Frequently Asked Questions
What alignment precautions does the A/390CBB shaft require?
The insulated through-shaft requires precise alignment to prevent optical reading errors. It is recommended to keep the radial load below 5 kg during startup to protect the ball bearings and ensure the encoder disc's lifespan by preventing mechanical displacement.
What connectors and output options are available?
It is available with 10, 23, or 26-pin connectors, such as the PT02A16-26P for IP65 protection, or the MS310A18-1P for compact applications. Electronic options allow you to choose between a standard parallel interface or an SSI serial interface, depending on the controlling PLC.
What are the environmental operating limits?
It operates reliably between 0 and +70°C in active operation, allowing storage from -30 to +85°C. For extreme environments, special options such as High Temperature (A) or Low Temperature (L) can be ordered to extend the standard operating limits.
How does it integrate with existing control systems?
It provides absolute position data upon power-up, eliminating the need for homing routines typical of incremental sensors. Its output stages support NPN configurations up to 12 bits for direct connection to industrial control inputs.
