HEIDENHAIN ERN 1387.020 incremental rotary encoder

The HEIDENHAIN ERN 1387.020 is an incremental rotary encoder designed for high-precision position feedback applications. Here is a detailed introduction:

Technical Parameters

Resolution: It has 2048 lines, which means it can divide a full rotation into 2048 equal parts, providing high - precision measurement of rotational position and speed.

Output Signal: The output is a sine - wave analog signal with an amplitude of ~ 1.05Vpp, which can be processed and converted by subsequent electronic devices to meet the needs of different control systems.

Power Supply: It requires a 5V (± 5%) DC power supply to operate.

Shaft Type: It features a tapered shaft with a 1:10 taper, a functional diameter of 9.25 mm, and back - off threads M10 and M6, facilitating installation on different devices.

Electrical Connection: The encoder uses a plug - in connector, which is straight, double - row, and 14 - pin, with a locking mechanism and walls. It offers both axial and radial cable outlets.

Protection Level: With an IP40 protection rating, it is dust - protected and can withstand certain mechanical impacts, suitable for a variety of industrial environments.

Operating Temperature: It can operate in the temperature range of - 40 °C to + 120 °C, demonstrating good temperature stability.

Features

High Precision: It adopts advanced photoelectric scanning technology, which can detect very fine lines, usually no more than a few microns wide, ensuring high - precision measurement results.

Good Stability: It has strong anti - interference ability and good temperature stability, enabling it to maintain stable performance in harsh industrial environments.

Easy Installation: With a built - in bearing and a stator coupling, the encoder can be easily installed on the measured shaft, featuring a short overall length and good dynamic performance.
