1. General Description

 

The TR-Electronic CEV65M-00444 is a robust, programmable absolute multi-turn encoder. It is designed to provide precise position feedback for both the angle (single-turn) and the number of rotations (multi-turn).

Its key feature is its programmability via the “TR-WinProg” software, allowing users to set the resolution, counting direction, and preset values. It communicates using the industry-standard Synchronous Serial Interface (SSI) with a noise-immune RS 422 output level, making it ideal for a wide range of industrial automation and motion control applications.

 

Key Features 🎯

 

• Absolute Multi-Turn: Provides unique position data for every shaft position, even after a loss of power.
• Fully Programmable: Resolution (steps per revolution) and the number of revolutions are programmable.
• SSI Interface: Uses the reliable Synchronous Serial Interface for data transmission.
• RS 422 Output: Provides a high-speed, differential (RS 422) signal for excellent noise immunity.
• Wide Voltage Range: Operates on a flexible 11…27 VDC supply.
• Robust Housing: Standard 65 mm industrial housing for high durability.
