Autonics E40HB12-120-3-N-5 is a high-accuracy incremental rotary encoder featuring a shaft inner diameter of Γ12mm and a resolution of 120 pulses per revolution (P/R), ensuring accurate motion tracking in moderate-resolution applications. It supports a maximum allowable revolution of 5000 rpm and is equipped with a NPN open collector output, which is ideal for seamless integration with PLCs and industrial controllers. Operating on a clean 5VDC Β±5% power supply, the encoder ensures stable output with low ripple interference, making it suitable for precise control environments.
This model features a radial cable connection that simplifies installation and maintains signal integrity during continuous operation. Its durable construction and compact size (weighing approximately 120g) allow for easy installation in constrained spaces. With an IP50-rated protection structure, the encoder resists dust intrusion, while its environmental range of -10Β°C to 70Β°C operating temperature and 35β85% RH humidity tolerance ensures performance across diverse industrial settings. A standard mounting bracket is included, adding further flexibility during system assembly.
The E40HB12-120-3-N-5 is commonly used in automated packaging systems, positioning tables, assembly lines, textile machinery, and material handling units. Its 120P/R resolution strikes a balance between speed and feedback precision, making it suitable for synchronized motion tasks and direction detection. Maintenance professionals rely on this model for its dependability and minimal calibration needs, while engineering students value it for practical training in encoder-based feedback systems. Designed to simplify diagnostics and improve accuracy in automation, this model stands out for consistent performance in real-world industrial applications.
