Single-turn Absolute Encoder A/345
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
Robotic and miniature applications require precise positioning without the bulk of external electronics. This A/345 Single-Turn Absolute Encoder integrates the encoding logic directly into a compact package, eliminating the need for additional circuitry to obtain reliable position data in demanding environments.
The integrated electronics ensure highly reliable performance despite the small size. It uses an LED light source with a lifespan of >= 100,000 hours and phototransistor optical sensors, guaranteeing continuous readings without the need for mechanical recalibration after each operating cycle.
Constructed with an anodized aluminum base and cover and a stainless steel shaft, it supports maximum radial and axial loads of 0.5 kg. It operates in temperature ranges of 0 to +70 °C and storage from -30 to +85 °C, and is available in guemisa.es.
- It integrates electronics for miniature applications without the need for external circuits.
- LED light source with >= 100,000 hours of guaranteed lifespan.
- Body and cover made of anodized aluminum for corrosion resistance.
- Stainless steel shaft supports radial and axial loads up to 0.5 Kg.
Technical Frequently Asked Questions
How does the standard A/345 model differ from the one with sealed bearings?
The standard model supports a maximum continuous RPM of 6000, while the version with sealed bearings reduces this limit to 3000 RPM for greater protection against contaminants. The low-torque option allows up to 8000 RPM continuous operation, ideal for high-speed applications.
What alignment precautions are required for the A/345 Encoder shaft?
Since it supports a radial/axial load of 0.5 kg and a starting torque of up to 25 gcm, it is crucial to ensure perfect coaxial alignment with the motor or actuator. Excessive misalignment can compromise the bearing life, which is rated at 1.5 × 10⁹ revolutions.
What connectors and output options are available for the A/345?
The encoder offers a standard parallel interface or an NPN open collector (10mA). The maximum resolution is 256 pulses per revolution (8 bits), with a maximum reading frequency of up to 50 kHz, compatible with high-speed data acquisition systems.
