Autonics E40H8-2048-3-N-24 Rotary Encoder

Designed with high-resolution accuracy and robust build quality, the Autonics E40H8-2048-3-N-24 delivers 2048 pulses per revolution (P/R), enabling precise monitoring of shaft rotation in motor drives and control systems. It features a standard Ø8mm shaft inner diameter and can sustain speeds of up to 5000rpm, backed by a maximum response frequency of 300kHz. The encoder provides A, B, and Z output phases through a NPN open collector configuration, ensuring reliable signal transmission to PLCs and automation controllers. The power supply range is 12–24VDC ±5% with ripple tolerance, offering stable and interference-free performance in electronically noisy environments. The radial cable connection type improves installation flexibility, while the compact design—just 120g—makes it ideal for space-limited control panels. Protected with an IP50-rated housing, it operates effectively in industrial conditions, within a wide temperature range of -10°C to 70°C and humidity up to 85% RH. This model is trusted by engineers for its low starting torque (max. 50gf.cm), helping reduce mechanical load during operation.

With its high-resolution sensing and durability, the E40H8-2048-3-N-24 stands out in demanding automation environments. Whether used in conveyor speed regulation or robotics positioning, its consistent feedback accuracy supports optimal control logic execution. The inclusion of a Z-phase allows for accurate home or index positioning—critical for synchronized multi-axis motion applications. Maintenance teams appreciate the hassle-free integration and long operational lifespan with minimal recalibration needs. Engineers and OEMs prefer this Autonics encoder not only for its electrical precision but also for its proven reliability in daily industrial use cases across manufacturing plants, process lines, and assembly automation setups.

Common applications for the Autonics E40H8-2048-3-N-24 include material handling systems, automated packaging equipment, industrial elevators, and indexing machines. In these machines, the encoder plays a vital role in delivering rotational data that drives the timing, speed, and position logic of the system. For junior engineers, it offers a practical understanding of how closed-loop feedback systems maintain accuracy and efficiency. For senior engineers, its stable 2048P/R signal enables precision calibration for motion synchronization and load optimization. The radial output simplifies wiring in compact control enclosures, and its rugged body ensures consistent performance even with frequent starts and stops.
