Single-turn Absolute Encoder A/390
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
The A/390 Single-Turn Absolute Encoder addresses the need for precise positioning in harsh industrial environments where conventional sensors fail due to vibration or dirt. Its robust metal housing ensures continuous operation under adverse conditions, eliminating the need for frequent maintenance on heavy-duty production lines.
The technical solution integrates robust circuitry within a hermetically sealed enclosure. It supports resolutions from 8 to 16,384 divisions per revolution, offering grayscale, binary, or BCD codes. The LED light source guarantees a lifespan exceeding 100,000 hours, ensuring stable mechanical angle readings without drift.
Built with stainless steel ball bearings and IP65 protection on the output side, this encoder supports a radial/axial load of 5 kg. Ideal for heavy machinery and automotive applications requiring extreme reliability. Available in guemisa.es.
- Extremely durable metal casing, oil, dust and moisture resistant.
- Configurable resolution between 2 and 14 bits for high-precision applications.
- Lifespan of ball bearings greater than 1.5×10^9 revolutions under load.
- Maximum electrical operating frequency of up to 25 kHz without distortion.
Technical Frequently Asked Questions
What alignment precautions does the IA020 shaft require?
The standard shaft has a diameter of 8 mm and must be perfectly aligned with the coupling to avoid unwanted axial loads. Low-friction bearings (option B) are recommended if the application involves extreme vibration, ensuring a long service life for the internal optical sensor.
What connectors and output options are available for the IA020?
The datasheet specifies multiple interfaces: standard parallel, serial SSI, or analog (current/voltage). Electrical outputs include open collector NPN (10mA or 70mA with PTC) for resolutions from 1 to 12 bits. Available connectors range from MS310A to DB25P, all with IP65 or IP66 protection.
What are the environmental conditions and operating limits of the IA020?
The encoder operates in a continuous temperature range of 0 to +70 °C, with storage between -30 and +85 °C. IP65 protection on the output side makes it resistant to water jets and dust, while the metal housing offers superior mechanical strength compared to standard plastic models.
How does this encoder integrate with modern control systems?
It supports direct integration via SSI serial interface (RS422) or proportional analog output (0-10V / 4-20mA). The Parity option allows automatic error checking during data transmission, and the Latch function freezes the outputs for stable readings under dynamic conditions.
