Safe, easy, flexible: Encoders for safe positioning

The AFS/AFM60S Pro is an absolute encoder for functional safety. It meets the very stringent test criteria according to IEC 61800-5-3 and is a certified safety product up to SIL3/PL e. The absolute encoder supports the safety functions in accordance with IEC 61800-5-2 and impresses in particular with its safe positioning function. Thanks to the high enclosure rating and large temperature range, the AFS/AFM60S Pro can be used in harsh environments. With its SSI and sin/cos interface, it can be easily integrated into a range of different controls. In doing so, singleturn resolution, counting direction and other parameters can be adapted individually. The integrated error memory detects important ambient data which provides support during installation and maintenance.

Certified safety product

The AFS/AFM60S Pro safety encoder stands for functional safety and fulfills very high safety requirements. The encoder is certified for applications up to SIL 3 / PL 3 and supports safety functions that conform to IEC 61800-5-2. The AFS/AFM60S Pro therefore guarantees safe positioning in stationary and mobile applications.

One thing is clear: The AFS/AFM60S Pro is safe.

Certified for applications up to SIL 3 (IEC 61508), SILCL 3 (EN 62061) and PL e (EN ISO 13849)

Simple safety engineering and simple encoder installation at consistently high machine and system availability

Supports the safety functions of drives in accordance with IEC 61800-5-2

Simplify the certification process for your system: The AFS/AFM60S Pro has already been certified by an external testing body and can be integrated quickly into your system.

Programmable and flexible

The AFS/AFM60S Pro allows for flexible integration into various controls with its SSI and Sin/Cos interface. It therefore has the decisive advantage of individualized adjustment of different parameters, e.g. encoder resolution and counting direction. Different mechanical variants and types of connector also increase the flexibility of the encoder.

Designed for different applications

Flexible implementation and adaptation options for new applications

The integrated error memory saves important ambient data and ensures high transparency of ambient and encoder functions

You can count on it: The AFS/AFM60S Pro stands for certified electrical and mechanical safety.

Complete package is easy to integrate

The AFS/AFM60S Pro can be implemented into systems quickly, easily and inexpensively. It makes it possible to realize safety functions for stationary and mobile safety applications in no time, especially in combination with other safety products from SICK. Thanks to the plug and play principle of the encoder, this is all very simple and offers the advantage of aligned safety products, for example for the implementation of complete solutions in the field of Safe Motion Control.

Safety encoders such as the AFS/AFM60S Pro play an important role when integrating innovative safety concepts for safe movement monitoring of machines and systems. For instance, the encoder is ideally aligned to the Flexi Soft safety controller, and the two devices create a powerful safety solution when used together: Safe Motion Control from SICK. It enables a very high level of safety and increases the efficiency of machines and systems at the same time.

How does Safe Motion Control achieve this combination of safety and efficiency? Precise differentiation of dangerous and safe machine movements at all times: The Flexi Soft safety controller monitors sensor signals and makes it possible to assess a dangerous state. If no hazard exists, the operator is permitted to intervene in the machine operation even during the running process – the process is not interrupted. Unnecessary machine stops and downtime are reduced in this way, increasing productivity.

Creating safe productivity – without interruptions

Safe Motion Control – safe productivity for stationary and mobile applications

Safe Motion Control offers a very high level of personal safety and at the same time ensures consistent performance of machines and systems. Safe Motion Control is therefore an innovative and powerful solution - for stationary and mobile applications alike. The operator can insert material into the machine by monitoring and reducing the speed of, for example, a metal press. It it no longer necessary to completely shut off the machine. Thanks to Safe Motion Control, automated guided vehicle systems (AGV systems) adjust their speed when persons are registered in the hazardous area of the system, thereby enabling effective use of the available space.

Productivity for a safe future

Safe Motion Control proves that the safety of machines, systems and persons does not automatically mean machine or system downtime. Thanks to Safe Motion Control, production or logistics processes can be monitored and controlled safety and permanently. The perfect combination, the certified AFS/AFM60S Pro safety encoder and the Drive Monitor FX3-MOC motion control module, ensures complete protection of machine or systems as well as the safety of persons. And all this with consistent machine and system availability and productive operation without interruption. Creating safe productivity. Now.
