Safety Encoders and Input Modules maximize machine safety.

Press Release Summary:

Model RVS58S Safety Encoders operate at 5 Vdc ±5% and deliver maximum output frequency of 200 kHz in operating temperatures from -20 to +80°C. Units handle axial shaft loads of 40 N at maximum 6,000 rpm or 10 N at 12,000 rpm, and radial shaft loads of 60 N or 20 N. Featuring 22.5 mm wide housing, VBA-2E-KE4-ENC-S AS-Interface safety modules snap on to 35 mm mounting rail, and provide 2 inputs for encoders. Both detect zero-speed, over-speed, and motion direction to ensure safe machine access.

Original Press Release:

Improve Productivity, Simplify Maintenance and Protect Workers with Safety Encoder-Based Safe Motion Solution from Pepperl+Fuchs

Solution enables operators and maintenance personnel to safely enter a guarded zone to setup and maintain a machine

TWINSBURG, OH – Pepperl+Fuchs introduces RVS58S Safety Encoders and VBA-2E-KE4-ENC-S AS-Interface Encoder Input Modules. This safe motion solution improves machine productivity and enhances worker safety by detecting zero-speed, over-speed and motion direction to ensure safe machine access during setup and maintenance. The system easily integrates into new machines or existing equipment, and is ideal in applications that demand SIL3, PL e and Category 4 certification.

"Using certified safety products to protect machine operators and maintenance personnel not only enhances overall machine safety, it also reduces engineering complexity and makes it easier to keep machines up and running through regular and proactive maintenance," says Helge Hornis, Ph.D., manager intelligent systems group. "As an example, using this solution in a rolling press application would enable the press to roll at creep-speeds in a safe 'expel-only' direction so that maintenance personnel could clean each roll far more efficiently than is possible with conventional machine safety options that completely disable motion."

RVS58S incremental encoders have a sin/cos interface, 1024 or 2048 signal periods and are thermally stabilized for high resolution interpolation. They operate at 5 VDC ±5% and deliver a maximum output frequency of 200 kHz in operating temperatures ranging from -20°C …80°C (253 K …353 K). They are rated to handle axial shaft loads of 40 N at maximum 6,000 RPM or 10 N at maximum 12,000 RPM, and radial shaft loads of 60 N at maximum 6,000 RPM or 20 N at maximum 12,000 RPM.

VBA-2E-KE4-ENC-S AS-Interface safety modules feature a compact 22.5 mm wide housing to minimize cabinet space requirements, and quickly snap into place on a standard 35 mm mounting rail. Each module provides two safe inputs for incremental encoders that monitor the standstill, rotational speed and direction of rotation on up to two axes of motion, and sends a safe signal via the AS-Interface network when a value falls below a set threshold.

Pepperl+Fuchs is a world leader in the design, manufacture and application of high quality factory and process automation products and services. Pepperl+Fuchs pioneered the development of proximity sensors 50 years ago, and has set the standard for innovation and quality ever since.
