Single-turn Absolute Encoder A/350
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
The A/350 Single-Turn Absolute Encoder addresses the critical need to know the exact angular position in a single rotation without having to count pulses from zero. In environments with rotating turrets or systems where mechanical return to the origin is complex, this device guarantees an immediate and reliable reading of the positional state.
The technical solution is based on a highly stable optical sensor consisting of an LED light source with a lifespan exceeding 100,000 hours and sensitive phototransistors. It offers a standard 8-bit resolution (256 positions) with a parallel output interface, allowing direct integration into digital controllers without the need for additional conversion.
The construction combines an anodized aluminum base for heat dissipation with an anodized aluminum cover, ensuring durability in demanding industrial conditions. IP65 protection allows for installation in environments with moderate dust or humidity. Available in guemisa.es.
- LED optical sensor with phototransistors for precise position detection.
- Standard resolution of 8 bits (256 positions) per full revolution.
- IP65 protection on the shaft side and industrial mechanical robustness.
- Lifespan of ball bearings at 1.5×10^9 revolutions.
Technical Frequently Asked Questions
How does the resolution of the A/350 model differ from other encoders?
The A/350 model offers a standard resolution of 8 bits (256 positions), although the manufacturer allows customization of the code and resolution upon customer request, ranging from 2 to 8 bits according to the specific requirements of the control system.
What mounting precautions are required for the A/350 Encoder shaft?
The stainless steel shaft supports a radial/axial load of 2 kg and a starting torque of 18/30/8 gcm. Maintaining proper mechanical alignment is crucial to prevent damage to the bearings, which are certified for a lifespan of 1.5 × 10⁹ revolutions under normal operating conditions.
What output options and connectors are available?
The standard configuration includes a parallel interface with a 10 mA open-collector NPN output. Variants with a 70 mA open-emitter NPN output and PTC are also available, allowing the signal to be adapted to different types of controllers and connectors depending on the system design.
