SICK AFM60A-S4NB018X12 Absolute Encoder

Buy online your SICK AFM60A-S4NB018X12 Absolute Encoder from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The SICK AFM60A-S4NB018X12 is a high-performance absolute rotary encoder from the AFM60A series, designed to provide precise position feedback for CNC machines, servo axes and industrial automation systems. Its absolute measurement technology provides position information immediately after power-up, helping eliminate the need for reference runs and supporting reliable closed-loop motion control.

This SICK absolute encoder operates from a 10–30 VDC power supply and uses a PROFINET communication interface for direct integration with compatible motion controllers and industrial networks. It provides a maximum resolution of 18 bit × 12 bit, corresponding to 262,144 positions per revolution and 4,096 revolutions, allowing precise position monitoring for demanding motion applications.

The AFM60A encoder is equipped with M12 connectors for industrial communication and power connections. The configuration includes one 4-pin male M12 connector and two 4-pin female M12 connectors, with axial connector orientation. The robust 60 mm housing is designed for continuous industrial operation in environments subject to vibration, temperature variations and demanding machine cycles.

The complete reference AFM60A-S4NB018X12 is important when replacing an existing encoder. Matching the full SICK code, PROFINET interface, resolution, mechanical configuration and connector arrangement helps maintain compatibility with the original servo system and simplifies installation and commissioning.

This SICK rotary encoder is suitable for CNC machine tools, rotary indexing tables, packaging machinery, gantry systems, material handling equipment and industrial automation. It can be used as a replacement unit, spare part or CNC replacement component when an existing encoder causes position errors, reference faults, unstable feedback or loss of absolute position information.

Keeping a matched replacement encoder in industrial spare inventory can significantly simplify maintenance following an unexpected feedback failure. The AFM60A-S4NB018X12 is also suitable for preventive maintenance, machine rebuilds and retrofit projects where reliable absolute position feedback is required.

Each unit supplied by Cnc-shopping can be tested on dedicated encoder test benches or motion simulators to verify basic functionality and communication performance before shipment. Units are securely packaged with protective materials around the shaft and connectors and supplied with a commercial warranty, with worldwide shipping and fast dispatch depending on availability.

The SICK AFM60A-S4NB018X12 can also serve as an emergency spare for legacy CNC and automation systems. Cnc-shopping can assist with sourcing obsolete SICK parts and may provide tested or refurbished units, repair services or exchange services when applicable, helping extend the service life of existing industrial equipment.

Frequently asked questions about AFM60A-S4NB018X12:

How do I confirm compatibility with my drive or controller?
Match the complete SICK code on your current encoder to AFM60A-S4NB018X12 and verify the electrical interface, connector style, mechanical mounting and resolution. If these elements align, the unit functions as a practical drop-in replacement.

Is this encoder singleturn or multiturn?
The AFM60 family covers absolute variants commonly used for multi-revolution position capture. Check your machine documentation and the full SICK code to confirm the exact variant required by your application.

Can this replace an incremental encoder on the same axis?
Only if the control hardware supports absolute feedback and the interface, wiring and scaling are compatible. Most replacements should follow the same encoder technology, so verify controller requirements before switching.

What should maintenance teams check during swap-out?
Confirm the nameplate code, interface, mounting fit and coupling condition, then preserve alignment while tightening hardware. After installation, verify position reading and reference status on the controller to validate proper operation.
