SICK ARS60-ADA32768 Sensor
SICK ARS60-ADA32768 hollow-shaft rotary encoder. 15 mm through bore, 32768 pulses per revolution for direct motor feedback.
Overview
The SICK ARS60-ADA32768 is a rotary encoder with a 15 mm through hollow shaft from the ARS60 family. Mounted directly onto the motor or machine shaft, it converts rotation into high-resolution position feedback, with 32768 pulses per revolution as indicated by the order code.
How It Works
The optical scanning system senses the shaft rotation and produces incremental pulses per revolution. The drive controller counts these pulses and derives speed and relative position. The hollow-shaft design mounts over the motor shaft, eliminating the coupling and its alignment effort.

Installation and Setup Notes
Slide the encoder onto the shaft and fix it with the recommended torque anchor; avoid hammering or axial shock. Verify that the shaft runs within the family's axial and radial runout limits. Configure the drive counter input for the pulse count and check the direction of rotation.
Frequently Asked Questions
What is the advantage of a hollow shaft?
Direct shaft mounting removes the coupling, shortens the axial length and avoids alignment errors.
Does it lose position at power-down?
As an incremental design, position is relative; for absolute values use the AFS/AFM absolute families.
What does ADA32768 mean?
The suffix identifies interface and the 32768 pulses per revolution of this variant.
