Welcome to the world of absolute single-turn rotary encoders, the precision instruments that define exact angular position within one full mechanical revolution (360°). Unlike incremental encoders, these devices output a unique digital code for each distinct shaft angle, meaning the position is known immediately upon power-up without needing a reference run. They typically feature optical or magnetic sensing technologies, with resolutions ranging from 10 to 18 bits (1024 to 262144 steps per revolution). Common electrical interfaces include parallel, SSI (Synchronous Serial Interface), BiSS, and CANopen, with supply voltages usually at 5 VDC or 10-30 VDC. Housings are often robust, rated IP65 or IP67, with solid or hollow shaft options (clamping flange or servo flange) for direct mounting on motors or machinery.
These encoders are the backbone of closed-loop control systems in industrial automation. You will find them in servo drives for CNC machine tools, robotics (articulated arms and gantries), and packaging lines where precise positioning is critical. They are also essential in medical imaging equipment (CT scanners), elevators, and wind turbines for pitch control. Their ability to provide absolute position without homing makes them ideal for applications where downtime must be minimized, such as in printing presses or textile machinery.
Our catalog includes subcategories like SSI absolute encoders, parallel output encoders, and fieldbus-compatible models (PROFINET, EtherCAT). Key article codes follow patterns like DTMEAST-XXXX-XX, where the first digits indicate resolution (e.g., 12 for 12-bit) and the suffix denotes shaft type (S for solid, H for hollow). For example, DTMEAST-12-S is a 12-bit solid shaft encoder. We also stock compact models for tight spaces and heavy-duty versions with shock-resistant housings.
