SICK (UK) has extended its high-resolution, programmable range of optical encoders with the AFS/AFM60 series for applications such as crank positioning of power presses and winch hoisting.

The encoders are suitable for use in harsh application conditions.

The AFS/AFM60 series includes a full range of solid shaft and hollow shaft absolute encoders.

The inclusion of programmable variants means that the encoders offer maximum flexibility for the system design engineer, and lower spares sticks for the end user.

The 18-bit resolution AFS60 single-turn encoder is ideal for applications such as crank positioning of power presses, turntable and carousel positioning, telescope azimuth and altitude positioning.

The 30-bit resolution AFM60 multi-turn encoder, which positions more than 4,096 turns, is suitable for use in winch hoisting, crane positioning, pitch adjustment on wind turbines, wave machines and tidal generators.

The AFM60 and AFS60 encoders feature a nickel code disk and optimised shaft- bearing arrangement, ensuring greater robustness and temperature resistance than encoders using glass and plastic code disks.

As a result, the range can be applied in ambient temperatures of -20C to +100C.

In addition, the two bearing races of the AFS/AFM are positioned more than 30mm apart, resulting in reduced run-out and smoother operation.

The wide bearing separation also enables higher radial load capabilities and longer bearing life.

There are three variants of the encoders: Eco, Standard and Advanced.

Eco types support resolutions up to 4,096 steps/turn, the Standard variant up to 32,768 steps/turn, and the Advanced model up to 262,144 steps/turn.

SICK said the range is versatile, each unit in the AFM/AFS60 series, encased in industry proven 60mm housings, is available as a servo-flange, face-mounted flange, blind hollow shaft or through hollow shaft.

Each model is mechanically identical to the equivalent SICK DFS60 incremental encoder, including the AFM variants, which feature integral gear-driven multi-turn stages for detecting multiple revolutions.

Both the AFM60 and the AFS60 communicate positional information to a PLC, or motion controller, using the Synchronous Serial Interface (SSI) developed by SICK Stegmann.

It is easily programmed using the same USB programming tool used with the DFS60.
