Part #: AD37/1220GZ.0W4W9

Safe things come in small packages… The AD37 encoder series for your functional safety servomotor system. Safety. It is ever on our minds. In particular, systems which use servo motors to autonomously move tools and work represent a real hazard to the worker’s personal safety. Increasingly, customers build systems with documented safety levels to ensure greater safety and reliability for these applications. By using standardized SIL levels, the level of safety can be independently gauged. It’s for these applications that the AD37 absolute encoder series, using ACURO secure interface, was created. The Hengstler ACURO secure interface was especially designed to provide high levels of functional safety in servo motor control systems. The interface protocol meets SIL3 requirements, while the AD37S encoder itself meets SIL2 and the AD37E encoder meets SIL3. With an operating temperature range up to +115°C and a 12,000 rpm maximum speed, the 28 mm mounting depth of the AD37 series makes it the most compact, absolute multiturn encoder in its class! The encoder contains both an encoder temperature sensor and an input to allow connection of the motor’s winding temperature sensor, putting that information directly into the encoder’s data. An internal “Electronic Data Sheet” in the encoder stores motor and encoder data, and can be recalled at any time. Safety. When you need a functional safety rating for your servo motor system, rely on the Hengstler AD37 encoder series and the ACURO secure interface!
