Sendix M3688 - Kuebler Absolute Encoder

The Kuebler Sendix M3688 is a space-efficient absolute rotary encoder built for dynamic, compact systems requiring reliable feedback in harsh conditions. With a 36 mm housing diameter and a magnetic scanning system, it offers high resilience against dust, shock, and vibration — making it perfect for mobile machinery and robotics. The encoder supports multiple hollow shaft sizes including 6 mm, 8 mm, 10 mm, and 1/4" blind hole variants, ensuring broad compatibility with various shaft designs.

Engineered with a flexible spring element or stator coupling flange, it enables easy mounting in constrained spaces. The encoder delivers resolution up to 14 bits (singleturn) and 18 bits (multiturn), balancing precision and performance for a wide range of industrial applications. Its IP65/IP67 protection level safeguards internal electronics from dust and water ingress, while the robust M12 axial and radial connectors provide versatile wiring options. Powered by a stable 18–30 V DC input, and supporting the modern IO-Link interface, the Sendix M3688 enables plug-and-play digital integration with smart fieldbus systems and condition monitoring platforms.

Weighing only 210 g, the Sendix M3688 Encoder stands out for its light weight and durability, especially in mobile automation, robotics arms, packaging lines, and medical-grade equipment. Its precise magnetic sensing combined with Kuebler’s engineering reliability makes it a top choice for high-speed, low-maintenance, space-critical environments.

The Kuebler Sendix M3688 Encoder is specifically designed for compact automation systems where space is limited but performance cannot be compromised. Its small 36 mm form factor makes it an ideal encoder for embedded robotics, AGVs (automated guided vehicles), and precision medical equipment where size, weight, and efficiency are critical factors.

In packaging machinery and small servo drives, the encoder delivers stable and repeatable position signals, even in environments with frequent vibrations. Its magnetic scanning system ensures accurate feedback without the fragility of optical components, making it suitable for dusty, humid, or shock-prone operations like woodworking machines or automated testing platforms.

Whether you are retrofitting a miniature robotic arm or building a next-generation sensor-driven conveyor system, the Sendix M3688 by Kuebler ensures fast, smart, and stable absolute position feedback with modern IO-Link connectivity — delivering high value in compact automation solutions.
