Baumer is a trusted global manufacturer known for high-quality sensors and automation components. Their rotary encoders convert rotational motion into digital or analog signals to measure angular position, speed, or direction.
Baumer offers both:
🔁 Incremental Encoders
🔄 Absolute Encoders (Single-turn & Multi-turn)
🔍 Types of Baumer Rotary Encoders
1. ✅ Incremental Rotary Encoders
Output: Pulses per revolution (PPR)
Reference point: Requires homing on startup
Use: Speed, direction, relative positioning
Example Models Output Types PPR Range
ITD 21, ITD 50 TTL, HTL, RS422 Up to 65, 536 PPR
EIL580 Series Push-pull, Sin/Cos Wide PPR selection
Applications: Conveyors, servo motors, robotics, textile machinery
2. ✅ Absolute Rotary Encoders
Output: Unique code for every shaft position
No homing needed after power loss
Use: Precise positioning in automation and robotics
🔹 Single-turn Encoders
Measure within one revolution (360°)
🔸 Multi-turn Encoders
Count multiple revolutions and position
Example Models Interface Resolution
MAGRES EAM580 SSI, CANopen, EtherCAT Up to 18-bit single-turn / 30-bit multi-turn
HOG 10 SSI, PROFIBUS, Modbus High-resolution, rugged use
Applications: CNC machines, wind turbines, elevators, factory automation
