Rotary encoder series for motion control systems
Posital’s Ixarc absolute rotary encoders include models designed for use in safety-critical motion control systems. The encoders feature redundant measurement elements and are certified to Safety Integrity Level 2 (SIL 2) and Performance Level d (PL d). They feature a Profinet communications interface and support the Profisafe protocol. Profisafe-based control systems are used for critical applications such as industrial robots or material handling equipment, where loss of control could result in hazardous situations. The encoder transmits a safety position and/or safety velocity value.
At the heart of the SIL 2-certified encoder is the magnetic measurement technology. The sensing elements in these devices are designed to be resistant to the presence of condensation and dust. Moreover, with no direct contact between sensing elements, Ixarc magnetic encoders will retain their accuracy and reliability over long lifetimes. Ethernet bridging functionality is built into the communications interface, which makes it possible to make use of a variety of network topologies. System troubleshooting is simplified by the presence of LEDs that indicate the device’s operating status and help to isolate faults. Saltwater-resistant aluminum housings make these devices suitable for use in harsh marine environments.
