Single-turn Absolute Encoder A/342
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
The A/342 Single-Turn Absolute Encoder addresses the need for precise positioning in rotating turrets and industrial applications where space is limited. Its compact design allows for easy integration into control systems without requiring complex external circuitry, ensuring mechanical stability in environments with moderate vibrations.
The technical solution is based on an unbreakable disk with a long-life LED light source and phototransistor sensors. It offers a standard 8-bit resolution (256 pulses) with a 5V ±5% Vcc power supply, consuming between 200 and 400 mA depending on the configuration, thus ensuring a low impact on the electrical system.
The construction utilizes an anodized aluminum base and cover for maximum durability. Sealed ball bearings ensure a service life of 1.5 × 10⁹ revolutions under radial load, supporting operating temperatures between 0 and +70°C. Available in guemisa.es.
- 8-bit resolution with standard parallel output for direct interface.
- LED light source with a lifespan exceeding 100,000 hours of operation.
- Anodized aluminum base and corrosion-resistant stainless steel cover.
- Service life of sealed ball bearings of 1.5×10^9 revolutions.
Technical Frequently Asked Questions
How does the A/342 model differ from the I/E6?
The A/342 is a single-turn encoder with a maximum resolution of 8 bits, while the I/E6 offers higher resolutions and more advanced output formats such as SSI or Bi-SSI. The A/342 prioritizes miniaturization for rotary turrets.
What alignment precautions does the A/342 shaft require?
The shaft must be perfectly centered and free of axial play to prevent premature wear of the sealed bearings. It is recommended to use a rigid coupling adapter that can withstand radial loads without exceeding the 50G impact limit.
What connectors and output options are available for the A/342?
It is available with a standard parallel interface or an NPN open-emitting KP option. One-meter cables with IP65 protection can be ordered, as well as high-temperature or shatterproof versions depending on project requirements.
