The EM20B4014000 is a 20 mm incremental rotary encoder designed for use in electronic equipment such as AV devices, home appliances, office machines, and communications gear. The document provides full electrical, mechanical, and environmental specifications, along with test procedures and safety cautions for manufacturers.
Key sections cover electrical characteristics (rated voltage, current consumption, output signal), mechanical properties (resolution, detent torque, shaft wobble), endurance testing (rotational life), and environmental limits (operating and storage temperature, humidity, vibration, and soldering conditions).
| Current consumption (typical) | 10 mA |
|---|---|
| Minimum input voltage | 4.0 V |
| Resolution | 40 pulses per 360° rotation |
| Operating temperature range | -10 °C to +70 °C |
| Insulation resistance (minimum) | 100 MΩ |
| Shaft wobble (max) | 1.4 mm p‑p |
| Rotational life (no‑load) | 500,000 rotations |
It provides 40 pulses for each 360° rotation.
The device operates from –10 °C up to +70 °C.
