AD37 with DQ Interface: Purpose‑Built for Siemens Servo Drives

Unlike resolvers paired with a protocol converter module (which adds ~$200 in cost, extra cabling, and proven reliability issues in outdoor/long-cable applications), the AD37DQ connects natively via DRIVE-CLiQ, eliminating the converter entirely and reducing both cost and failure points.

With the leading competitor discontinuing their small-diameter DQ encoder, the AD37DQ is the only compact (≤38mm) drop-in alternative on the market; competing replacement encoders are simply too large to fit the tight mounting constraints found in medical imaging equipment and compact linear actuators.

Why DRIVE‑CLiQ Matters in Siemens Drive Systems

DRIVE‑CLiQ is Siemens’ digital, Ethernet‑based interface for motion feedback devices. It enables fast commissioning, automatic device recognition, and reliable real‑time data exchange between motors, encoders, and drives. DRIVE-CLiQ is a native digital communication protocol that allows encoders to connect directly to compatible drives and controllers without any intermediate hardware. This enables for cleaner, faster, and more reliable position feedback across the entire system.

It is the standard interface across a wide range of medical imaging equipment and industrial servo motor applications, making protocol compatibility a non-negotiable requirement for suppliers entering this ecosystem. The AD37 with DQ interface is designed to plug directly into this ecosystem. No gateways. No configuration workarounds.
