Available. The Heidenhain 823901-52 is an absolute rotary encoder from the EQN 1325 series, designed for precise position and speed control in industrial automation applications. This encoder features a tapered shaft with a functional diameter of 9.25 mm and back-off threads M10 and M6, ensuring a secure and stable connection. It operates within a voltage range of 3.6 to 14 V and provides a binary output signal of approximately 1 V peak-to-peak. The encoder offers a line count of 2048 and a cutoff frequency of 400 kHz, facilitating high-resolution measurements. With an operating temperature range of -40°C to +115°C and a protection rating of IP40, it is built to withstand challenging industrial environments. The electrical connection is a straight, double-row, 12-pin plug connector with a locking mechanism, suitable for both axial and radial cable outlets. A mounting kit, including spacer plates and a central screw, is included for easy installation. This encoder is a suitable replacement for models 538234-01 and 515385-01.
