Single-turn Absolute Encoder A/350E
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
Precise position determination on rotating turrets requires an absolute encoder capable of maintaining the reference without recounting after each cycle. The A/350E model offers absolute encoding from 2 to 8 bits, guaranteeing angular data integrity even in the event of power interruptions or severe vibrations in demanding industrial environments.
The technical solution integrates phototransistors and an LED source with a lifespan exceeding 100,000 hours, ensuring long-term optical stability. The standard parallel output interface allows direct reading of Gray or Excess codes without additional conversion, optimizing response time in control systems operating at up to 6000 Hz continuously.
Constructed with an anodized aluminum base and cover, the device supports radial/axial loads of 2 kg and protects the internal circuitry with an IP65 rating at the output. Its robust construction allows for reliable operation between 0 and +70 °C, making it ideal for applications requiring mechanical durability and impact resistance up to 50 G.
- Integrated absolute encoding from 2 to 8 bits without the need for manning.
- Standard parallel output compatible with open NPN collector or emitter interfaces.
- ball bearing service life greater than 1.5×10^9 revolutions under load.
- IP65 protection at the outlet and resistance to mechanical impacts of 50 G.
Technical Frequently Asked Questions
What alignment precautions does the encoder shaft require during assembly?
The shaft is made of stainless steel and supports a radial/axial load of 2 kg, but it is vital to avoid excessive angular misalignment that could compromise the bearings' lifespan. A certified rigid or flexible coupling is recommended to maintain the integrity of the internal optical system against external vibrations.
What connectors and output options are available for the A/350E?
The device offers standard parallel interfaces as its primary option, with the ability to configure open NPN outputs as collectors (10mA) or emitters (70mA + PTC). Custom Gray or Excess color codes can also be ordered, depending on the required resolution, adapting the number of conductors to the available wiring.
