MOTION CONTROL: Pepperl+Fuchs introduces RVS58S Incremental Rotary Encoders with integrated safety technology. RVS58S encoders with self-diagnostics are specifically 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. They are also suitable as a motor feedback system for safe drives in accordance with IEC 61800-5-2.In response to these needs, Pepperl+Fuchs developed the RVS58S rotary encoder with functional safety that enables economical system integration. This new concept provides easier connection methods to the control system and allows it to be used in high safety category systems. The RVS58S incremental encoders have a sin/cos interface, 1024 or 2048 signal periods, and are thermally stabilized for high resolution interpolation. They operate at 5V dc ±5 percent and deliver a maximum output frequency of 200 kHz in operating temperatures ranging from -20 to 80C (253 K …353 K). They are rated to handle axial shaft loads of 40N at maximum 6,000 RPM or 10N at maximum 12,000 RPM, and radial shaft loads of 60N at maximum 6,000 RPM or 20N at maximum 12,000 RPM.
