Single-turn Absolute Encoder A/359

Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS

The A/359 Encoder solves the critical need for precise positioning in demanding industrial environments, offering an internal star-type structure with patented coupling to ensure mechanical stability and reliable zeroing without constant external intervention.

Its architecture supports configurable resolutions from 4 to 2048 positions (PPR), integrating high durability phototransistors and allowing multiple output interfaces such as parallel, SSI or analog for direct integration with motion controllers.

Constructed from anodized aluminum with IP65/66 protection, it withstands vibrations and impacts of up to 50G, operating stably between 0 and +70°C. Available through guemisa.es.

Configurable resolution from 2 to 11 bits for specific applications.
Versatile power supply with options of 5V, 15V or wide ranges of 8÷30V.
Robust anodized aluminum housing resistant to 50G impacts.
Bearing life exceeding 1.5×10^9 revolutions under load conditions.

Technical Frequently Asked Questions

What alignment precautions does the A/359 axle require?

The hollow stainless steel shaft requires controlled torque during installation to avoid compromising the bearings, ensuring that the radial and axial load does not exceed the mechanical specifications of the original datasheet.

What connectors and output options are available for the A/359?

26-pin IP65 or 23-pin IP65 connectors are offered, with electronic outputs configurable as open NPN, Push-Pull or analog depending on the interface selected in the manufacturer's order code.

What are the environmental conditions and operating limits of the A/359?

The device operates between 0 and +70°C with storage up to +85°C, resisting standard vibrations and 50G impacts thanks to its sealed housing and certified high-life bearings.

How does the A/359 integrate with existing control systems?

Compatible with standard parallel interfaces, serial SSI or analog current/voltage outputs, allowing direct connection to PLCs, servo controllers or data acquisition systems without complex external adapters.
