Single-turn Absolute Encoder A/3115R
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
Harsh industrial environments with oil, dust, and moisture demand robust sensors that are essential in critical applications. The A/3115R Encoder is specifically designed to withstand these adverse conditions without compromising the angular accuracy required in heavy machinery.
The extremely robust double housing and long-life optical sensors ensure reliable operation. With an impact resistance of 50 G (11 ms) and ball bearings designed to withstand a radial/axial load of 18 kg, it guarantees mechanical stability under severe vibrations.
Constructed with an anodized aluminum base and stainless steel shaft, it withstands operating temperatures from 0 to +70°C. For more information on availability and specific configurations for your industrial project, please consult guemisa.es.
- Extremely robust double casing for harsh industrial conditions.
- Oil, dust and moisture resistance guaranteed by encapsulation design.
- Lifespan of ball bearings greater than 1.5×10^9 revolutions.
- Output compatible with resolutions from 1 to 12 bits.
Technical Frequently Asked Questions
What precautions should be taken during axle assembly?
It is essential to ensure that the mating surface is flat and free of contaminants to prevent damage to the bearings. The stainless steel shaft has a standard diameter of 8 mm, but custom variants with different diameters can be ordered upon request.
What connectors and output options are available for the interface?
The model supports multiple interfaces, including parallel, SSI, and analog. For robust connections, IP65-rated connectors such as the PT02A16-26P or MS310A18-1P are available. Electronic options include output (70mA+PTC) for resolutions from 1 to 12 bits, in addition to standard open NPN.
What are the environmental operating and storage limits?
Optimal operation is guaranteed between 0°C and +70°C, while storage can withstand extreme temperatures from -30°C to +85°C. The housing protects against moisture and dust with an IP65 rating for the cable and IP66 for the connector connection, ensuring durability outdoors.
