Rotary encoders with integrated safety technology - Pepperl+Fuchs

The RVS58S incremental rotary encoders, with integrated safety technology, are designed for use in safety-aligned systems up to SIL3 in accordance with IEC 61508, performance Level “E” in accordance with IEC 13849, and Category 4 in accordance with DIN EN 954-1. The encoders, with self-diagnostics, are also suitable as a motor feedback system for safe drives in accordance with IEC 61800-5-2.
The encoders have a sin/cos interface, 1,024 or 2,048 signal periods, and are thermally stabilized for high-resolution interpolation. The encoders operate at 5 Vdc ±5% and 200-kHz maximum output frequency in temperatures ranging from –20 to 80°C. They are rated to handle 40-N axial shaft loads at 6,000 rpm (maximum) or 10 N at 12,000 rpm (maximum), and 60-N radial shaft loads at 6,000 rpm (maximum) or 20 N at 12,000 rpm (maximum).
